I'm running Microsoft Windows XP Professional. A couple of weeks ago I was hit with a lot of spyware/malware/junk, and I thought I had cleaned most of it up using HijackThis, Ad-Aware, Ewido, VundoFix, and maybe some others. Since then, however, my computer has started rebooting itself, seemingly at random. Although I had some overheating problems in the past (a year ago or so), my PC has never rebooted itself before--it always only gave me warning beeps.
Now, it reboots itself and I can't figure out why or what triggers it. Sometimes, when the computer has been off all night, I turn it on to try to check my email, etc., and it reboots within a minute after startup (so it doesn't seem to be a heating issue). Other times it has rebooted while surfing the net, while playing a game, while I'm using MS Word, while just sitting there with the screensaver on, etc. Sometimes it will reboot itself 3-4 times in a 20 minute period, and at other times I can use it for hours without a problem.
Once, the computer rebooted itself immediately after I unplugged my modem (I was online at the time) to run some spyware scans. Since then, I have noticed that every time I unplug the power to my cable modem while online Windows pops up with a message saying: "Local Area Network cable unplugged". About 10 seconds later, the computer reboots.
I think this is related to the spyware/viruses I got a couple of weeks ago, because the problem appeared that same day (or the next), and I had never had it before, although I've had this computer for almost 2 years. Any help will be greatly appreciated,
