System Fails to POST

order28 · 04-17-2008, 03:53 PM

Hi All

I have a ASUS P5ND2 SE MB, INTEL 6300 DUO, ASUS 1950 PRO, 2GB RAM RUNNING WIN XP, WITH A 550WATT ATRIX PSU.

Today I was playing a game when the screen froze. Tried ctrl alt del but could not get anything so had to switch off power and reboot.

When I rebooted I could not get it to POST. No beeps at all. It is a PHOENIX bios.

I have tried taking the cmos battery out of 15 mins, and rebooted with same problem.

Then tried using just one memory module and nothing.

Tried no memory, and nothing.

Tried disconnecting Graphics card, no change.

Tried disconnecting HDD, no change.

Having read previous posts on similiar problems it sounds like the MB or PSU to me.

Is there anyway I can narrow it down further?

Many thanks.

turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
replace the battery
put the side on
replug in the power lead
boot the computer
the power supply is low quality see if you can borrow aquality psu to try in it

Thanks Dai

Tried the CMOS reset but no change.

Will try the PSU option next.

Many thanks for your assistance
