I'm inclined to agree with divine. Thats classic PSU symptoms.

We've got plenty of spare PSUs in work - I could bring one round after work on Monday (or sometime this week) if you want to confirm the problemmo. Lots of RAM as well, although most of it is old.

It does in fact sound like PSU problems, however I have family machines perform exactly like your description when the CPU cooler bracket came loose.

Upon boot up the CPU rockets in temperature instantly, (you'll notice the main fan 'revs' high for a second before settling at it's usual pitch), alot of systems will cut out instantly rather than risk the CPU temp reaching a damaging state.

Best bets are to open up, double check all connections- again, look for any unusual signs before guessing and RMA-ing/replacing

Cheers brigster... if you can get a spare PSU to test out that would be grand. I'll try and find some time to run some visual checks, so expect to hear more over the comming days.

right well if it wasnt the PSU before, its definitely gone now... Woke up this morning and the computer was ticking, it had somehow turned itself on. Then, just got back from work and turned on the mains plug at the wall, and computer whirred to life without me hitting the on button.
I've replaced the PSU with one that Briggykins lent me, which is fine, but is 'only' 300W so I've not plugged everything in to it.

Anyone got any recommendations for power supplies? It needs to run:
Abit AN8 ultra mobo
Geforce 7800 GTX
one case fan
Front panel display
2 optical drives
1 floppy
1 sata drive (I think its sata II... if that matters?)

The unit that is gone is a modular one, Hiper Type R 580W beast. Was a bit noisy all its life and I don't know if I went overboard with the power when I built it or not.

Advice required please

Once PSU is replaced, I'll see if other problems still remain.

I've got a Corsair TX650w and it's been faultless. It's not modular which is one downside, but it's silent (I mean literally, I can't hear a thing from it) and comes from a long line of good reviews. 650w might seem a bit high, and it probably is for now, but you won't need to worry about it supporting SLi or a better CPU/Mobo in 6 months or whatever, it will cope with it easily.

bit pricy tho

iCraig · 20-04-2009, 17:42

Yeah I guess it is, but if there's one component to invest in it's the PSU. I wouldn't want a bog standard £20 unbranded thing powering a decent PC. Some machines have £500-1000 worth of components running off that thing, you just don't want to risk it killing them for the sake of £30-40.

An AMD64 machine will happily run on 450W (decent brand, Corsair are good in their TX and VX range)

That'll sort you nicely.

Was looking at that actually Divine, or the OCZ Stealth Xtream 500W
