I bought a rebuilt computer a year ago, used it once, shut it off and now it won't boot. I have done a lot of searching and for the last 2 days feel like I am getting somewhere, but now I have hit a dead end. I have made 3 different rescue cds and 2 found nothing, but with the last one, avira antivirus rescue cd, the results came back with 3 alerts.... [unexpected end of file]/media/devices/sda2/windows/system32/catroot2/edb00428.log and 2 others ending 00429.log and 0042A.log My question is how to I get rid of what ever is causing this so i can get into windows. After it wouldn't boot, I contacted the person I had bought it from and he said that there wasn't any virus protection at all on the computer. That would have been nice to know before I shut it off. I feel like a dummy because I didn't know this before. Before I did the rescue cds, I was in the "infinite startup repair loop" and the first time, I got corrupt registry as the root cause, then I did some research on that and used cmd to copy and I think I fixed that cause now I get a baddriver as a root cause. Please, can anyone help?

log files are not infectable, more than likely you have bad sectors on the hard drive but is pure speculation, you don't give much information on what happens when you attempt boot, Operating System, error messages etc. More detail on what exactly you have done. Edit your question and give us much more detail. I don't suppose you got a legal copy of the OS installation disc and product key from the seller? –  Moab Jan 17 '12 at 1:15
    
I have done so much...chkdsk came back no bad sectors. This is what I get when I try to do startup repair. Signature 1 and 2 6.1.7600.6385, sig 3 unknown, sig 4 -1, sig 5 AutoFailure, sig 6 1, sig 7 Bad Driver. Locale ID 1033. Before I got corrupt registry, but i did the copy . to mybackup in the registry. as for the system restore i get error code=0x1f. It's windows 7 32 bit from what I can gather. –  dwilbanks Jan 17 '12 at 1:58
    
And no I don't have the original disk, but I made a recovery disk for windows 7 32 bit and it reads it. i could get to the startup repair options. but ever since I used the cmd cd=\windows\INF <enter> notepad setupapi.app.log <enter> regedit <enter> and loaded a hive and found the bad driver (PCI\VEN_14E4&DEV_1677&SUBSYS...) and typed 4 in the data value, when I boot via the disk, it freezes in the cmd screen. –  dwilbanks Jan 17 '12 at 2:02

I would clean reinstall the OS. Almost all the google hits have almost no solutions for this issue, one suggested to remove all but 1 ram module, see if it starts, if it does, do all your Windows updates before re-installing the other ram modules, but this was for Vista. –  Moab Jan 17 '12 at 2:07
    
Would you happen to know how to burn the hard drive so I can do a clean install? I haven't done that in over 10 years, and I am sure there are easier ways now then there was back then. –  dwilbanks Jan 17 '12 at 2:27
