Complete dead computer!

post #1 of 8
Thread Starter 
Just got the following

Intel i5 3750k
Asrock Z77 extreme 4 motherboard
MSI GTX 680
Kingwin 600W power supply

All worked for 3 days then the following happened in this order

I Left the house to go out > dumb sister tried to use the computer > I got home pushed the power button > The computer powers up and dies in 2 seconds after 4 seconds it powers up and dies in 2 seconds repeat forever > replaced the power supply for a newer 80+ silver > same outcome > 3rd power supply > same outcome. Dumb sister says same thing happened to her.. B.S.

I took each component out one by one to test. so it must be the motherboard or the CPU which cannot be tested separately ( PC will not turn on without CPU )

I have to make the trip to MicroCenter to replace both

what would kill my motherboard? besides the obvious dumb sister of course. I noticed that when i plugged in the main power for the motherboard it would flex horridly, but again why would it work for 3 days and then die?..

Have you tried resetting CMOS?

Plus you will learn to love your sister in time. Just wait until your 20 wink.gif

Take everything out of your case and try and try to start it up with the core components installed on an anti-static mat.
