sometimes when i power on my PC it starts but suddenly power off itself and in a few seconds power on by itself again .I have Intel d946gzis board ,Intel dual core 3.2 . Pls help me sort out this problem. do i need to change my psu ? thanks
My Asus board will do the same thing if it fails to post from overclock errors. It then boots with all default settings. Does your intel board have an option like that? If its not holding an OC, might be part of the problem.
If you want to rule out the PSU, try to borrow one from someone and see if it still has the same issue.
