Dead PC - Help!

[[email protected]]

Hi

I'm looking to upgrade my old spare PC and bring it up to date - but when I try to turn it on at the mo it's dead. I want to upgrade it sensibly as I only built it 2 years ago and many parts should be still fine - case, PSU, drives etc, - but I don't know what parts are fried. Your thoughts please... symptoms are:

Power supply connected, all internal connections appear fine, it hasn't been tampered with since I last turned it on about 6 months ago. It has the Standby LED light on on the NForce 4 mobo, so the mobo is getting juice, but when I press the power switch nothing happens. At all. There is also an on-mobo power switch and that's not working either, so it's not the case switch that is faulty. There are POST diag lights onboard but they don't even flicker. Nothing at all happens.

So what do you think is likely wrong? Is it mobo/cpu, or could it be PSU - could the PSU be giving a base level of juice to light the mobo LED, but not firing up when switched?

TIA
Bert

PS - PSU is Antec True Power 440W.

firstly what repalcement parts can you borrow from other moachines, this will cut down on cost of buying random parts. secondly, have you tried clearing your cmos (refer to your manual or remove the battery on your mobo for a few hours then replace the battery and try turning on again (this may remove all saved bios settings)).

if you are wanting to upgrade your pc, i suggest posting the current specs and budget up as well since it will help the forum in tellign you what to buy.

Hi

Can't really get any parts to play with unfortunately. Current spec is:

DFI LANParty NForce 4 Ultra
Athlon 3500+
BFG 7800GT OC
1GB DDR400
Antec TruPower 440W
250GB SATA Hitachi Deskstar

Spec I think I'm looking at:

Giga GA P35 DQ6
Intel E6750
(Brand?) 8800 GTS 320GB
2GB DDR (what speed?)
Corsair HX 620W
Stick with current HDD

After reading up a bit, I have concerns that my old 440W could handle this new system anyway, so I think I'm just gonna have to do the lot...

Any thoughts on my current planned new spec?

Thx

any brand gts is fine
5300 ballistix ram
the corsair is overkill on that rig

are you going to be overclocking your new pc?

Corsair 620 is overkill I know, 550 or so would be fine, but for the sake of £20 or so it gives me some future-proofing...

Overclocking - yes probably.

I'm still curious as to what the issue is with the existing set-up - any ideas?

have you tried resetting the cmos as i suggested? if so have you tried a new bios battery (this can be obtained in most hardware or computer stores) or from another machine. a dead battery may or may not be your problem
