When starting my computer it powers down after the beep. the longer I try andthe power supply runs the farther I get into the startup. Finally it starts up Windows 7.
When on line when I swich functions it shuts down. Laely it shuts down every night over night.
I'm using a Biostar 870-U3 MB, AMD Phenom II X4 955 CPU, Crucial 2 GB DDR 3 1333 Ram- 4 sticks.
I had problems with the OS when starting and had to register it by phone. Could that be a problem?
