My desktop at home has all kinds of bad shit going on. Curious if you guys have any ideas: I've already formatted the HD the operating system is on and reinstalled the OS (twice), but I still have symptoms, which are: - Firefox crashes constantly, semi-randomly. - any large archives I download, .rar, .zip, or .exe formats will be corrupted (fail CRC checks left and right when I unpack them). However, I seem to be able to download other files with no problems, no matter how large. - the machine has blue screened (not a typical bluescreen, a stop message) a couple of times. - twice since I've reinstalled the OS, I've had drivers start randomly malfunctioning - usually several at once. I'll reboot the machine and the network and video drivers will be broken and need to be reinstalled Now the thing that irritates me the most is that I've already formatted my main drive. That said, I have a second drive which I didn't format and I left connected, so the most obvious thing seems to be that the other drive has some shit on it, and I'm getting it back after I format and reinstall the OS. The other alternative is that I have some more serious issue, with the BIOS or something (which I've considered flashing, but haven't yet). I've scanned both the formatted drive and the other drive with AV software multiple times (I'm using Avira, at the moment), and gotten a clean bill of health. So my next two moves are probably: 1. Flash the BIOS, and if that doesn't resolve anything, 2. disconnect the second HD and format again. Any other ideas?
