How to escape chkdsk at boot when keyboard & graphics fail?

Specs: Windows 7
For awhile now my computer has initiated chkdsk every time I reboot it. I usually skip it no problem. But recently following a power outage, I hit the buttons on my USB keyboard only to discover there was no response and the chkdsk continued. Unfortunately in times prior when I decided to let it run its course it got hung up and then just restarted the computer. This remained true in this case.

Searching around I realized the USB keyboard problem is common. I found a ps/2 keyboard only to realize I don't have the input on my computer. The keyboard works fine during the BIOS screen. unfortunately I don't seem to have a USB Legacy Mode available. I desperately tried to repair holding F8 or selecting F11 for system recovery only to run into another irritation, the graphics card would give out during repair or the chkdsk process. Once I decided to let chkdsk run its course as the monitor showed No Input and the computer rang a couple beeps: one was 2 short 1 long which I believe is Video, and the other what I believe to be 8 quick beeps, which I think is bad/overheated processor. Any help on the matter would be greatly appreciated.

Sounds like one of your ram sticks is bad. Faulty ram can corrupt data on your hard drive and that is why your system would run a chkdsk. I would try swapping the ram around so that you can isolate the defective one.

You can also download a memtest image file and create a bootable cd or flash drive to test the memory:

But your problems may extend beyond bad ram. Post the specs for that machine and if possible check the beep codes for that specific model.

Thanks for responding. I swapped the ram around and indeed had an incident with one stick of ram in particular, whereupon the computer refused to boot and made a long series of beeps. So I'm guessing that would be the one which is provoking the chkdsk to occur. Though currently I have no idea, as every time I get the computer going, the graphics goes out. So at this point I'm of the belief that the biggest problem is the video card (ATI Radeon HD 5700), which I'm guessing needs to be replaced.

Is the inside of your case dusty? You may want to clean the contacts on your video card and ram with rubbing alcohol to clean them up, also make sure that there is no dust inside the memory slots or the pci-e slot. If the rubbing alcohol doesn't seem to be getting the gold contacts bright and shinny, use a soft pencil eraser to polish them up, then go back over them with the alcohol.
