The other day when I was to use my computer it had locked up, it didn't responde to keyboard so I pressed reset. Instead of restarting it simply shut down. Pressing the power button resulted that the fans sped up just to shut down again immediately. A short beep can be heard but I'm not certain if it's the mobo that produces it. Since then I get the same result every time I press the powerbutton.
These are the things I have tried so far:
- Replacing the power supply, waste of $60.
- Resetting the CMOS by removing the battery
- Removing the connector to the power button from the mobo and carefully shorting the pins on the mobo with a screwdriver. Which felt a bit nevous to do :)
- Removing the connector to the reset button from the mobo and try the power button.
- Remove the power button again and short the pins instead.
Nothing I did gave any change in behaviour. The computer simply spins up for a second, gives a strangled beep and then dies.
Are the any more things I can check to see if it is the mobo or some other components that fails?
My mobo is a Gigabyte GA-MA770-UD3AMD770. Secondary questions is if any one knows a good (though not too expensive) mobo and maybe cpu to buy. My cpu is old, AMD Athlon64 X2 5200+2.7Ghz,2x512Kb,64-bit and the RAM I'm using is Corsair TWIN2X 6400 DDR2, 4096MB CL5.
All advice happily recieved.
