Hi everyone!

I'm new to this site, and need your help desparately (me without computer = me without oxygen; it hurts). Here's the problem:

I was surfing the net when a small mechanical "click" came from my computer. Immediately, the monitor stopped receiving signals, and blacked out. The power continued to run, but nothing else happened. When I restarted the computer, there was no POST, no beep, and no display. The optical drives did the usual spin-up, but after that, there was nothing. Any ideas as to what could be wrong?

My system specs are:
Gigabyte 8KNXP motherboard (dual bios, dual power system)
Intel P4 3.0 Ghz 800 fsb
2 x 512MB Kingston DDR PC3200 RAM
ATI Radeon 9600 graphics card
2 x 120 GB Western Digital IDE HDDs
Creative Audigy 2 ZS sound card
420W PSU

So far I have tried:
reseating RAM and booting
removing RAM and booting
reseating all cards and plugs

Thanks in advance!

Hi!

I would say, your motherboard or the powersupply.

Hi, do you have any tips in terms of pinpointing the problem?

Thanks.

Well, if it is the motherboard, it's pretty hard to troubleshoot,
But you could take out all cards, except the video, and see what happends?
This will ease the strain on the PSU. IF it boots o.k.? Then put in another card and boot etc.
Also check your mobo for any leaking capasitators or burnt areas.
Check if the PSU fan(s) are spinning and if you can smell anything burnt from it?
Check all cables from PSU.

Thanks, I'll reply back in a few days when I get a chance to test out all the suggestions.
