Hi there, im having the next issue with my setup:
P5GCMX1333 (LGA775)
Core2Duo E4500
1gb DDR2
PSU 500w Kelyx

So im having the issue with the onboard video (VGA) sometimes it doesnt work (monitor black - start in power save mode) the %80 at turning on the PC it doesnt work. I have to reset like 20 times to the video work and when it work, the computer works fine.

I tried updating BIOS to the last version of the mobo, didnt work.
Using a GPU, didnt work.
I changed the thermal paste from CPU, Northbridge and Southbridge.
The battery BIOS is new.
I did reset the BIOS by using jumper a lot of times.

Update: • Tried with 4 PSU even with 1 EVGA 500w 80+ bronze certificated.
• I just clean the northbridge and put new thermal paste.
• Tried with a GPU.


Not even appear the pre boot message from bios.

The monitor works fine im using it right now, never had a issue with others PC.

Anyone know a solution? Ty.

 
I found an article stating it was the CMOS battery, however you stated the bios battery is new. The next logical thing to try is replacing the power supply. I've had very similar issues with my computer only when overclocking and messing with the voltage. That being said, it appears your computer is displaying symptoms that would suggest there is a power issue of some kind. I'd go out to a local computer hardware store and purchase a replacement power supply. If it doesn't work out, you can always return it.

Forgot to say, i already try with 4 different PSU, even with 1 EVGA 500w 80+ Certificated, more than enought.
And with different RAM, switching between banks, even without conecting the hdd.
The RAM works fine on other computer its the mother having a failure.
