I have a friend who's computer has just recently misbehaved. It keeps restarting at intervals and rebooting. To me this sounds like the Sasser Virus. I asked another relative of mine who knows computers and told him about it and he said it wasn't the Sasser virus as the virus only affects the Windows XP, 2000 systems. I downloaded the Sasser Virus removal tool from another computer as the friend's computer i was trying to fix had no internet. The internet went as well. The computer has got very slow.
In all this assuption that the problem may or may not be a virus, Seorise did say the machine in question has no internet. Am I right? If I am - No internet - No virus unless hes has downloaded a passed on disc [ floppy or CD]
This sounds more like a a power supply motherboard problem intermitant power supply
