Hi everyone!

Here's what happened: I was using my computer as normal with no hardware issues. One day I booted it up and heard a long beep with 3 short beeps and no video. I checked the manual for my Asus P6T motherboard and this code means it doesn't recognize VGA. I have two Nvidia 9800 GTX in my computer, so I took one out and tried it in both PCI-E slots, then did the same with the other, and I get the same beep code. To be safe, I went down from 12 GB of RAM to 4 just in case. Same thing. This happened out of no where. No hardware changes, lots of air flow, no dust clogging anything up. Any suggestions would be greatly appreciated.​

Alright, so I reset the BIOS and tried another video card. Looks like my two 9800 bit the dust at the same time. Not sure what happened. I tired another video card and it works. But now I have a second issue. Since I reset my BIOS, now windows won't load. I have windows 7. It comes up to the starting windows screen then reboots. I've had this before. I think it has something to do with AHCI. Before the BIOS clear it was enabled. I re-enabled it but still getting the same thing. Last time I had to reformat in order to get everything back up and going again. Anyone have any suggestions?

If you have the install disk for the OS, boot to it and do a REPAIR.  It will hunt down the needed drivers and get the OS running again.  It doesn't affect any user files, just the OS and the needed drivers for the hardware found, even if the hardware has changed,  BUT the identification on the install disk and the hard drive have to match.

Tried that. No dice. I even ran bootfix. Same thing... Do I have any options other an reformatting? I can backup my data, but it's just annoying to do it.

I can't see any other options.  I would remove the hard drive and see if it can be accessed using another machine to remove critical files before reformatting.  If you had the install disk, it would onlyNEED a REPAIR, but the numbers on the disk and on the OS that's presently installed have to match, it would boot and find the appropriate drivers (video) for the hardware that is detected.  You'd be up and running in an hour. I always buy the OS so I always have the chance to repair after a hardware failure.  You could build a whole new machine, drop the drive in and it would find the drivers and get the OS going again.

I do have the original install disk. The video is working now, it's just that windows isn't booting. Repair didn't work. Looks like a-way I go backing up and formatting. Thanks everyone.
