I'd bet at dislodged memory or pci/e cards.

pull the ram and see if it posts, then poke other stuff in better.

Hmm, even with a fan pointing at it it's still running hot.

Is there any way I can reduce the voltage without destroying stuff, or does it not work like that?

Information:

CPU - Intel Pentium 4 570, 3816 MHz (19 x 201)

kinda-ish, but I wouldn't (less volts often means less stability)

It's an old Prescott, which always ran slightly hotter than the sun, So i'd not worry too much unless your machine is still unstable under gayming.

if you open coretemp, above all the temps, there's a bit called Tjunction, what does that say?

Won't let me run the CoreTemp thing - gibbers something about it not being Intel core architecture.

piss.

Scouring the net yields a review that claims max temp is 72.8C - I think this may be wrong given that I'm currently at 79C

I have the 3.4ghz version of your processor and I've had loads of problems with heat. It throttles at 76C which will lower performance alot so you definately want better cooling in there.

If you decide to get a new CPU cooler, these are supposed to be really good for the price: http://www.ebuyer.com/product/105994 Just make sure you clean off the old thermal grease first. Also, if there's anywhere to mount some case fans then you definately should.

Try putting your machine on its side so it lays motherboard down, if your heatsink isn't fitted well, it might get a bit cooler.

Also maybe worth replacing the heatsink with something new and better (but may not be easy to do if you have an odd machine)

Strangely enough, what everest is telling you isn't really particularly accurate. I think your CPU doesn't have an internal temperature probe.

In short, your CPU temp could be showing a higher or lower than it actually is, depending on where probes are, and how accurate they are.

Run it while you play a game and see if your CPU throttles, if it does it's getting too hot.

is a good idea.

I appear to be being throttled like a gimp on a short leash.

Edit: just tried turning it on it's side and it made a sound like a chainsaw going through wood. Whoops.

Most likely

Heatsink not mounted well - touch the side of it while the machine's running/warm (use an unimportant finger) if the heatsink isn't hot, it probably just needs re-seating. if your finger sticks to it, it's crap and you need a new one (heatsink, that is, your finger will probably heal)

Or

Fucked/clogged up heatsink or fan that's not really doing its job. - Assuming your machine has the standard 4-legged heatsink mount jobbery going on (if you're not sure, post a few photos) buy that heatsink lee linkied, I've heard good things about them.

Heatsink ordered. I've just remembered that I've problems with it previously. Last time my PC and they replaced my hard drive, they said it had overheated due to the ball bearings in the fan wearing down quicker than usual.

Mind you, it was from Evesham

Well I poked everything, still not working. Probably going to have to take it to the PC repair shop on Monday then.

and this is why you should build your own machines

no idea then, could be summat cooked

Well the repair people reckon its the power switch and the motherboard but they want to charge £120 to fix it which is a complete rip off considering a new mobo will only cost £30.

Only problem is I have no idea how to fix the switch myself, as far as I can tell it's all moulded into the case with no easy access, I'll have to have a better look once we get the PC back from them.

For testing, there's a nice easy way to do it.

locate the front panel connectors bit on the motherboard, use a screwdriver to short the power switch connectors on the mobo (only for a second though)

the machine should start as normal.


if that works, the easiest way to fix the problem is using the reset switch wire to the power switch connectors.

Just tried shorting the power things and it does the exact same thing. So that narrows it down to the motherboard then I think.

I'm going to double check the PSU again just to be sure first though, since that can be replaced under warranty. I might try putting the PSU in my own PC to confirm if it works or not, is there any risk in doing that if the PSU is dodgy?
