I'm having an issue that I've been working on for a while and its driving me nuts. I caught a virus a few weeks back (I think, couldn't actually find one) that filled up my C drive to capacity. I decided to just reformat and reinstall XP but everytime I try I get a stop error 0x0000007b. I googled it but haven't really gotten anywhere because I don't think its a harddrive or a driver issue and I'm a bit leery of playing around with flashing my BIOS. I know it isn't my harddrive because I removed it and tested it with another and am getting the same error. I also checked my BIOS settings, with only one harddrive I don't use RAID (altho it is an option) so I don't think its a driver issue. I was able to install Linux and now I'm running Vista, although I don't really know what that tells me except that everything physically seems to be working fine. Also, I've twice now gotten a 'boot disk failure, insert system disk...' error prior to Vista starting up and then after I restart it worked fine again. Sorry I don't have the exact specs on my computer. The motherboard is a Gigabyte with a 3ghz Pentium D chip with 1 Gig of ram (1 stick). Both harddrives I tried were western digital (one a 40 gig, the other was a 160, both IDE drives). At this point I don't even know if its a software or hardware problem - not too good with computers, so any help would be appreciated! Thanks!!
