Hi, guys!

For some reason, my (custom) computer doesn't always boot up correctly. I press the power button and the fans and stuff come on but the screen doesn't...

It does not boot up past the fans. And I sometimes have to try several times make it to boot up.And sometimes it starts the first time.

I took it to a repair shop but they couldn't figure it out. I think the guy wasn't so good nd he wasn't able to give me any hint...

Anyway, any suggestions?

Hi, Bob!

I can think of a few possible reasons.

First, do you see the BIOS loading up? If you do, high chance: the mobo is allright. If you don't even see thie BIOS, it means the mobo is screwed and it's time to get a new one, my friend...

Otherwise, it could be that the CPU is fried or damaged or not connected properly. You can check for that.

Other possibility: did you check all the card connections? A lost PCI connection could easily cause such unstable behaviour.

It would help if you could describe exactly when it hangs and what is seen before.

Hope this helps.

I'm also fixing a computer for a guy who has the same exact problem. Although, his will rarely start correctly.

The first peculiar part is that as soon as the computer is plugged into the wall, it turns on without pressing the power button. But, aside from that, there is no HDD access - the access light only comes on for a split second when the computer turns on. The DVD-ROM lights up and seems to be accessable. All the fans run at what seems to be "full speed," very loudly. No video at all.

I've only gotten it to start normally a couple times... seemingly randomly. I've reset the CMOS a few times. Checked all connections. I don't understand why it will start normally occasionally.

This issue sounds almost EXACTLY like the problem I'm having with my wife's HP laptop currently. I can't seem to find any particular reason for the times that it does and doesn't restart. Once it's up and running, it will stay running until it is either restarted in any way, or goes into sleep/hibernation. Then it's a crap shoot as to whether or not it will boot again next time. I have noticed that the unit does seem to be awfully warm and I'm considering opening it up to check the fans and CPU heatsink.

Did you have any luck in finding your solution?

I saw your post about the computer not starting up. I'm running a 3 year old Power Spec desk top on XP, and yesterday my computer now won't start up at all. When I hit the power button, it starts to power up for about 2 seconds, and then shuts itself off. I also have to recycle the on/off switch for the power button to work. I've cleaned everything out, all fans appear to be running (except the graphics card, but it doesn't even get far enough to display the BIOS on the screen), and all connections are in tact. All new and frustrating behavior.

Do you have any other ideas for me? Thanks

Your first step should be to try a new power supply. If that doesn't work, then, unfortunately, you've got a bad motherboard. That's what happened with the PC I was working on. The new power supply made no difference. It was actually the motherboard that was at fault.

Just check to make sure all of your cards and memory are seated properly, and the power button connection is OK. Some people have had problems with a faulty power button.

I have an older ASUS P4VP-MX w/ 2.8 Intel CPU that is doing about the same thing. I have an expensive capacitor tester at work and found some caps that needed changing and now it starts, but it"s weird. In the beginning it hesitated to start. I could continually push the start button and that would get it going. Then after that nothing. I changed the caps and it started right up. Now, it's the same thing. Also now when it is started, it will run for a while and then die. It almost seems like something is overheating. I have ordered another motherboard. I will use the old CPU and see if it does the same thing or not. Any suggestions would be greatly appreciated. I'll post what I find out.
Thanks Clay

When I turn on my computer mouse is not functioning properly like if I click a icon it is not opening even right clicked the small window is not opening, then I press the start button on the keyboard then the mouse works correctly.

Please provide me a solution to rectify this problem.

I'm having this problem also.

It is a brand new computer. This has happened from the start.

Sometimes it starts. Sometimes it starts, you see it all starting like normal. then it reboots and the screen doesn't come on. The speakers make the power off and on sound so it's not just a screen issue.

To answer the previous person here is a solution I have found ages ago, which still seems to solve some problems.

My friends computer started but the screen didn't it was like it was in standby mode all the time. I told him:

Unplug the screen, the power cable from it, and leave it 24hrs. Then plug it in and start your computer. Somehow it drains it fully of power and stops the standby situation.

Hope this helps, if anyone can help me then please do.

I had a similar problem and was able to fix it by removing one of my RAM cards. It turns out if one of your RAM cards are going out or are dead it will do nothing but the fans will run and nothing shows up on screen. Take out your ram and switch them around and see what happens. Chances are if its only part of the time your ram is starting to die. and its easy to switch them around try running it with one if the problem persists, try with the other. If there is still a problem switch it around and if there still is you may have to check if your cpu is completely in the computer. Check the motherboard, cpu, but first check the RAM. I did not think RAM would effect bios startup but it did on mine and removing the faulty card fixed all the problems. I hope this helps!!

Problem:
I would switch on my laptop (sony vaio), the lights would turn on, but nothing would happen, the bios didn't start up, it just sat there in black emptiness.

Solution:
I removed 1 of the ram memory cards, and it worked fine after that. A miracle!

Funny you mention the ram fix, cause I had the same problem with an old computer and managed to get it to start after playing with the memory (removing all the cards and playing with them) and resetting the bios.

My new build just did the same thing today. I went to school and came home and it wouldn't show anything. I checked the ram the, the video cards and then it eventually stopped booting up into windows. I saw that someone mentioned to try and check for shorting of the motherboard. Pulled it out and it started right up. I don't see how it could of come lose when I just built it on last Monday. Hopefully this helps your problem or reduced down your list of problems.

Thanks

Kahula, on Nov 20, 2008 4:50:31 am GMT

Along the same lines, I just finished a brand new build (even had to send the MOBO and Vid back for new ones) for a graphics workstation PC running Vista. The PC won't start up unless I manually power down the PSU for at least five seconds, repower, and hit the power button. Otherwise, the computer will boot up but I won't hear the system beep and I'll not get any video. Once I've done my method, I can restart, etc. As long as I don't go into sleep mode, all is well.

Any ideas?

I just finished a new build, but unfortunately it does not work. The fans of the case start running, as well as the CPU fan. The HDD (i thing it starts running) because you can hear it. The VGA card-fan works, so I assume the card works as well. The problem is, there is no display. From what I have read on forums, it could be anything from the CPU being fried, RAM being bad to the VGA display. I tried leaving just one RAM dimm at a time, to check if any of them is bad, but still no display. The power source works just fine since its fan is spinning, and all the other fans that get voltage from it, work.
So what can the problem be? How can I check if it is the CPU ? Or can it be the motherboard?

Hi Radu,

I would suggest that you try each memory stick in the primary location if you haven't. They are normally different colours, and one memory holder on your motherboard is primary. I don't know if that will help but it's worth a try.

Another thing you could do is take working memory out of a working computer and try using that. That way you will eliminate the memory issue.

The next thing you could try is ensuring your monitor works by testing that elsewhere. Sometimes they have a wierd powersaving mode. I have found in the past that if you fully unplug that from the wall for about half hour and try again it sometimes works.

GOod luck buddy

Thanks for the answer.
I found the problem. The wire (which was an extension actually because the one from my PSU was too short) was faulty. So i replaced it, and now it works just fine. The wire I'm talking about is the 4 pin 12V, that powers the CPU and for my mobo, goes up into the mobo, near the CPU. I'm just glad it was only that, very inexpensive fix :D

Hey people!
i'm having almost the same problem as bob666, but mine will make ambulance-sounding noices for about 5-10 minutes while starting up, and its very odd. it just started happening around 2 weeks ago, but until then, everything has been fine. So does anyone know what might be causing those noices? my dad is getting mad because they are loud and high pitched and very annoying, and im only 13, so i dont know much in the matter. well, if anyone knows, please repond. thanks!

I've have the same problem with my HP tx1000 laptop,
after being on the line with HP services for almost two hours
I had to unscrew the bottom part of the laptop where the hard drive and chips were,
after switching the two chips and pulling out the hard drive and putting it back in my laptop was fine
every now and then it doesnt turn on, but usually after 3 tries it works

*doesnt recommend fixing it my way*

Though now, my laptop occasionally just goes into sleep mode while I'm using it.

I pluged in my dvd player via a usb cable and my pc shut down without notice. Now it won't boot up at all. It will turn on and all the fans run and I can hear the HDD start to run but no video or beeps. I think maybe the dvd player fried something. I've tried removing the ram, unplugging the usb cable from the mb but nothing works. The mb power led lights up so I'm thinking maybe the cpu is toast but I don't know how to check that and I don't want to buy a new one and find out that's not the problem. Any suggestions? I've also tried switching the hard drives but that did nothing.

I have sort of the same problem with my computer. See, I got a new video card that is an ATI RADEON 2400 AGP (4x/8x), and at first, it works, and it still works, to play spore... But, a few weeks later (last year in June), my computer screen would just be blank, have a blinking cursor, or freeze at the windows loading menu. Then, when we took it out and put it back in, it was fixed. For about 1 month. But then it happened again. We then installed an ATI driver, and it was fixed. But the same thing happened again. New driver, and again. Honestly, this is getting annoying. I can't find a cheap motherboard that is like mine. It is a socket 478 with 1 agp slot (8x) and the other 3 are PCI, and there are 4 RAM slots (DDR). If there is a way to fix it, could someone please tell me?

Hi im experiencing similar problems with my custom built computer. It is a AMD Athlon 6000+. It chooses when to start. Sometimes it bleeps, sometimes it has a long bleep with no screen. I have to switch it on and off many times then finally it loads up properly.

The weird thing is that when it loads up, i can restart or turn it off and it will load again, no problem. But when i leave it switched off for a long time, then i have to play this game again.

I changed my ide hdd to sata, still no change. At first i had my 24pin power socket mobo connected with my 20pin psu. I was told that i have to connect it with a 24pin psu. I then purchased an adapter, still no change. The computer shop told me it may be RAM.

Im confused, somebody help....................

I got a simular problem, it looks as if my computer boots as it should but the screen will only start for a couple of seconds an it dies before it shows anything. i read earlier that there where someone who had an amd athlon, i do to mayby there is a cpu problem? some manufacturing fault perhaps. i know sounds unlikely but you never know.

I got a similar problem, when i turn on my PC everything starts running (Fans HD, CD Drives etc.) but no video post, I sent the motherboard to get "fixed" and its a GA-P35-DS3L Gigabyte motherboard, they told me it was a bad chip and they fixed it somehow, as I got it back i rebuilt everything and it still does the same thing then i saw the CPU power cable (4-pin connecter) wasn't plugged so i thought that was the problem so i plugged it back in but the same problem aslo as i try to turn it off, 1 second later it starts back up again, I've tried Diffrent RAM and graphic cards. Could it be that the procceser burnt out or the motherboard is still bad and they just lied to me about fixing it.

Sync issue is with the monitor. In your case when Windows loads up it is doing so at a very high resolution, beyond your monitor's display capability. Simply plug it into some other monitor with better resolution display capability. It will boot up fine. Right click on the desktop and choose 'Properties' >> bring down the resolution to 1024x768, click 'Advanced' button, click 'Monitor' tab at the top and make sure the screen refresh rate is 60 Hertz. OK both windows. Shut down the machine. Put back the original monitor. It should boot up fine this time. Now go back into display properties and choose the maximum capability of this monitor.

Been suffering with the same issue for a while, usually i get the monitor to start by unplugging the vgd chord and (this is gonna sound weird but trust me it works) U know how when your car's battery dies and u tub the wires against it so u get that spark and then start the engine this is exactly what i do, i unplug the chord turn the pc on without the vga chord connected then rub and plug it back, turn the pc off manually ofcourse then back on.
