Computer restarts suddenly sometimes. Please help.?
Hi, I am running windows xp professional service pack 2 x64 edition and when i first installed it everything was working great. Then after a while, my computer began to restart suddenly when it reaches the logon screen or when it is logging on and even sometimes when I am restarting it. It doesn't happen that often but it does happen and I want to know why. No blue screen shows up. The monitor and windows just resets by itself. This never happens when I am using the computer, meaning when I successfully log on. It only happens either when I am logging in, logging out or rebooting the computer. The error report stated that it might be a virus but I am doubtful. i ran avast on my computer more than once and no infection was detected. I used some online scanners like e-set and bitdefender and still, no virus was detected. I have always had my antivirus and firewall up-to-date and besides, the computer seems to be working fine when I get to the desktop. It is not slow, does not get stuck and it shows no unusual behavior. In the report, Microsoft also said that it might be a problem with my drivers. I think that they are all correct but I can never be sure. Please, can you suggest what this might be, from your own personal experience perhaps, and can you explain to me how to fix it. If it is a problem with the drivers, can you tell me a good program that will check my drivers and make sure that they are all correct and up to date.
Thanks a lot-Any help would be immensely appreciated :)
