Hello,

I am having a problem with my desktop running WIndows Vista Home Premium. There are a variety of problems that occurred while I was trying to fix it, let me start from the beginning as it may help in identifying the problem.

So I left my desktop on when I left for work. It was working fine, no problems. I came home to find it powered off, I didnt think anything of it, assuming that my wife had turned it off to save energy. I turn it on and it starts waaaayyy slow. Then it gets to a black screen that says it can't boot from my Hard Drive and for me to enter my Boot Disk. I do so and it sends me to the VIsta Installer. I go to the Repair option and when it comes up, it says no Hard Drive detected. I turn it off and go to BIOS to see if BIOS can help. I change the boot order to Hard Drive first, since it was set to floppy (I don't even have a floppy), then to CD second. I then save and restarted. Same problem with the black screen and boot disk. I go to BIOS and restored the Defaults, saved and exited. Same problems after restart. I then proceeded to change the video input from its default to PCI-E since I'm using a PCI-E Video card. Now it won't even send any signals to my monitor. I've tried plugging the monitor to different ports, the original port, the S-Video to my TV, and the PCI-E monitor slot on my Video card. Nothing works. Now it won't even send signals to my mouse or keyboard. I think I really messed it up. I've been reading on the forums about people with similar problems, but nothing exact. I've tried to unplug the power from the PSU for 30, 40, 60 seconds and plugging it back in, but nothing worked. I'm pretty stumped and kind of frustrated. I've also read that it might be an IDE or SATA cable thats malfunctioned, or it could be that my hard drive decided to croak, or maybe even a bad Mother board.

I haven't checked to see if it was the mother board or the cables, since I'm tight on cash. Is there a way to maybe set the BIOS back to default without a screen? Is that even the problem?

Any help would be very much appreciated.a
