Hello,

I use windows xp sp2 on computer and am unable to boot it up successfully. I am at a loss for what to do.

This is what happened. My computer became infected with a nasty virus so i tried to boot up in safe mode using F8. However I got a blue screen with an error message that said:

"A PROBLEM HAS BEEN DETECTED AND WINDOWS HAS BEEN SUT DOWN TO PREVENT DAMAGE TO YOUR COMPUTER.

IF THIS IS THE FIRST TIME YOU'VE SEEN THIS ERROR SCREEN RESTART YOUR
COMPUTER. IF THIS SCREEN APPEARS AGAIN FOLLOW THESE STEPS:

CHECK FOR VIRUSES ON YOUR COMPUTER. REMOVE ANY NEWLY INSTALLED HARD DRIVES OR HARD DRIVE CONTROLLERS. CHECK YOUR HARD DRIVE TO MAKES SURE IT IS PROPERLY CONFIGURED AND TERMINATED. RUN CHKDISK /F TO CHECK FOR HARDDRIVE CORRUPTION, AND THEN RESTART YOUR COMPUTER.

TECHNICAL INFORMATION:

***STOP: 0x0000007B (0xF7B6D528, 0xC0000034, 0x00000000, 0X00000000) "

Every attempt to boot up in safe mode brought me to this screen. I then tried booting in safe mode through msconfig. I still received the blue screen error message. However now I receive it no matter how I start windows. Specifically when I try to boot up I am brought to a black screen with the message stating:

"We apologize for the inconvenience but Windows did not start successfully. A recent hardware or software change might have caused this.

If your computer stopped responding, restarted unexpectedly or was automatically shut down to protect your files and folders, choose Last Known Good Configuration to revert to the most recent settings that worked.

If a previous startup attempt was interrupted due to power failure or because the power or reset button was pressed, or if you aren't sure what caused the problem, choose Start Windows normally.

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt
Last Known Configuration
Start Windows Normally"

I tried using last known good configuration as well as booting up normally but ever since I tried booting in safe mode with msconfig everything brings me to the blue screen error message. My best guess is that windows is now stuck in trying to boot up in safe mode but thats based solely on the course of events. I don't have a windows disk, only Microsoft Windows Recovery Console installed. I'm in much need of help and any insight would be very appreciated.

Configuration: Windows Me!
Firefox 2.0.0.20

It doesn't seem to be the drive. In fact I thought I had fixed it for a second. My hunch was correct as far as windows being stuck in safe mode and safe mode being rendered inoperable by a virus. I used the recovery console and the bootcfg /rebuild command to rebuild the boot.ini. That made windows boot normally instead of in safe mode and I was able to logon to windows. I immediately scanned for viruses and found a boatload. Seems I got a trojan downloader originally. All signs of anything nasty disappeared (popups, strange running processes) and I could restart my comp normally just fine. But my windows firewall wouldn't function, and safe mode still brought me to a blue screen error.

I should have figured a virus was still present but, frustrated at this point, I tried to fix it directly. I found that msconfig wasn't where it should be (c:\windows\pchealth\helpctr\binaries) but found a backup in another windows folder through file search and moved it. I tried starting in safe mode with f8 again, but again, was met with the blue screen stop error. But this time when I tried to boot normally I received the "A PROBLEM HAS BEEN DETECTED AND WINDOWS HAS BEEN SHUT DOWN TO PREVENT DAMAGE TO YOUR COMPUTER." error screen, so I chose last good configuration that worked. The windows xp logo pops up, the screen goes black and the cursor pops up, then suddenly before reaching the desktop it automatically reboots. It doesn't give me the "A PROBLEM HAS BEEN DETECTED" screen this time and just brings me to the blue screen of death.

It now continues this way, error detected - last good configuration - automatically reboots - blue screen. Or I choose to boot normally and get the blue screen. Rebuilding the boot.ini doesn't work. Neither does checking the disk for errors. I should mention the stop error code is slightly different now from what it was originally. Instead of 0xF7B6D528 that part is now 0xF7AAD528.

I think a virus is infecting my mbr or it's otherwise screwed up, but I'm afraid to mess with it. I read you could end up with an inaccessible drive, especially if it there is a virus. At this point I'm wondering if I can get a virus program that I could run from a bootable cd. Or if a windows installation cd could help somehow, like repairing windows installation or something, and if so, if I can use any since I never got a windows xp cd with my computer.

Again, any help or insight would be appreciated. Thanks for your time.

Seems you get a driver error.
It is the most common windows error.
clean your registry is the most efficient way to fix blue screen.
so you can boot into safe mode.
do a PC clean.

Hi,

I'm also experiencing similar problem. My message reads "irql not less or equal." I can't boot up windows in any modes (safe, regular, last good known configuration, etc). It all brings me back to the Blue Screen.

In Safe Mode I get a different error "page_fault_in_nonpaged_area."

Have no idea what to do. Please help.

Thanks,
Alex

If you are still around vatul, I have the same problem

I think i got a virus/trojan of some kind while in the process of changing antivirus software. The new software wouldnt load properly and wanted to delete certain files in safe mode. I used the boot.ini function in msconfig
and now I get the same blue screen as you, whether I start in safe mode or full mode etc

STOP: 0x0000007B (0xF7B38524, 0xC0000034, etc)

how did you get out of this? what is the recovery console and bootcfg/rebuild command?

can anyone help, please

I have managed to get back on by scouting the internet

1. insert windows xp disk
2. enter bios setup
3. change order of startup to cdrom as first and harddrive as second
4. enter recovery console from the disk
5. at c: windows prompt enter bootcfg /rebuild
6. y
7. Microsoft Windows XP Home Edition
8. /fastdetect
9. exit

restarting should work
