Computer doesn't boot up, sometimes..

Hi all,

Sometimes my computer doesn't boot up. The fans, lights and hard drives boot up but no POST, beep or anything on the screen.

However, after a few tries at resetting it, or powering it down and starting it again it will boot up just fine. It'll be perfectly stable after this, as well.

I have four sticks of RAM, and I have tried taking some out. I have also tried disconnecting fans to free up some power.

Here is my spec:

Q6600
Asus P5KC motherboard
4GB Crucial RAM
Corsair 520W power supply
ATi Radeon 2600 Pro graphics card

Any ideas what is (or is not) happening?

I was wondering whether or not the board is receiving enough power - but surely a 520W PSU is fine?

Here are my voltages (all default):

Hi,

Thanks very much for the info. How do I know what to increase NB to?

Ok, I am sick of this. I spend half an hour of rebooting, taking out RAM modules / putting them in again just so I can get it started up. Sometimes, if I am lucky it will go past the POST without locking up.

Forget adjusting the voltages, as it forgets everything when it fails to boot.

I'm just going to replace the whole lot. Screw ASUS.
