No beeps = RAM problem.

Thanks for replies
No light at monitor, I have connected my laptop to monitor and it works fine.
Have now disconnected all drives so motherboard, video card and power supply are only items live.
No output and no beeps, reconnected HDD same result.

Have you done anything with regard to memory? Memtest86?

Remove all but one module, re-boot, repeat, one module at a time.

If you can get acess to a pci video card try to, and install it as a test.From what you say your monitor lite doec not show., thi means no signal from card to monitor.Also check the cable from card to monitor.

Hi
Thanks for all your help
After exhaustive tests, lots of substitution and sleepless nights, it turned out to be a faulty power supply!

How did you determine that it was the psu - substitution?

Terrific that you tracked down the problem, best of luck!
