Hey guys, I'm having file corruption issues. I originally posted in the software thread thinking that it was a virus issue, but I've wiped and rewiped my drives and still seem to be having the problem. My original post is here: http://www.techspot.com/vb/topic100472.html So basically, every time I reinstall windows, I end up getting corrupted system files and/or registry. Chkdsk runs and deletes a bunch of information and restores a bunch of orphaned files (even files that I deleted get restored). This has happened to me on two separate Hard drives...one of them brand new. The OS seems to run OK, with some lagging, but every time I reboot chkdsk runs and does the same thing, and I get a registry message "One of the files containing the system registry had to be recovered by use of a log or alternate copy. The recovery was successful" My question is that if it was a virus, it should have been toast from the kill disks and reinstalls, but my problem keeps coming back. I've done a memtest and all three of my RAM chips checked out OK. Could it be my motherboard or CPU that is corrupting files due to errors in data processing/transfers? I always thought that hardware failures would be obviously spectacular. It is a little expensive to randomly start replacing components (its a home built system, been running just fine for 3 yrs up to this point).
