Very strange. Defect modem,router,hardware in general etc. ?

Bad processor, bad memory, bad motherboard etc.

I would go to minimal conifg and see what happens.

That is only the motherboard, the processor, the least amount of ram you can (meaning one stick only), 1 hard disk and the grahpics card.

Then see what happens.

And yeap try switching out PSU as well.

Still same damn problem? Reflash your BIOS with an older one or a newer one if your not up to date.

Thats all I can think of atm. Still tired from working 14 hours yesterday.
