What are you using for Antivirus and Firewall?
It sounds like you are running with scissors.
Recently a problem began on my PC. The monitor would go black and the HD light stayed on bright and steady. Whatever the cause, it was apparently erasing the OS files. The only way out was to hit the power switch (which I was loath to do with the HD running, but...). After reloading Win98SE twice I decided to go ahead and make the switch to XP-SP2 (which I'd purchased on sale a couple of weeks before) and see what happened. Result: same game - except I was on guard and managed to power down before much damage -AND - XP is better at repairing damage to itself. I'm guessing the problem was malware on the 30 Gb HD. So I backed up my 26Gb worth of files to CD (no OS files) and replaced the HD with a new Maxtor 80G HD. I've slowly reloaded selected files to the new HD and thus far no problems. After all that - THREE questions:
1) Given the symptoms, does anyone have an idea of what problem or malware I'm dealing with here?
2) How do I get rid of it? (as far as I know its still lurking somewhere in the backed up CD files...)
3) I'd like to REuse the (infected?) 30Gb HD as a second drive. Can the whatever-it-is migrate to the new 80Gb drive if I reconnect the 30G drive, boot up and then format it before accessing any files on it?
All hints, comments, suggestions, information welcome!
