Whenever I start up or restart the PC... it will load to the Login screen... and if I Login to quickly it will open Windows for about 2 sceonds then it will reset it self. If I let it sit at the starup screen for a minute, then login... it works fine. It has been doing this for as few months... no new hardware or software, no virus... auto deleate spyware every couple of days. Any thoughts on why this is happening?
