Computer STILL switching off randomly

Prime95 is a stressing program, usually used to check overclock stability but in this case it could tell us if cooling or load is the problem.

Calm down no one will want to help you if with comments like that. PLEASE explain what you're talking about, many times ive said i don't know all the technical jargan since i'm kind of new to this.

Not sure about temps switching it off though it seems most likely, But what.. Graphics card, psu? What should i recheck to try and stop this happening? (And how)

Sorry if it seemed like i was being harsh or something and i entirely did not mean it in any way.

Thermal paste is what is put in between your CPU and the heatsink - or fan used to stop it from overheating. It is used to help transfer the heat off the CPU and onto the heatsink. If its not applied well it can sometimes cause heat problems.

However if your temperatures are correct which you have posted above then i don't think CPU overheating is any trouble.

I dont get it thoguh, when i first got it it didn't switch off, then it started to switch off once i put in my HD 4670, now that ive put in my new PSU its still doing it -.-

What card did you have in before, and did you install the drivers for the 4670 correctly?

Erm, i had a GT9500.

Also, i'm not sure.. Everytime i try to install the drivers 1 thing doesn't install correctly.

Microsoft visuals or something, always fails.

Need help guys, my pc wont even stay on for a few minutes now BUT... ive discoverd something.

If i keep my small room fan fanning into the inside of the pc it doesn't switch off :S How can i fix this...

james.miller · 8 Sep 2009 at 16:03

if that fan is actually keeping it running, and the cpu and gpu temperatures are fine and you've already discounted the psu, then its either the ram or the motherboard itself.

is the ram hot, and i mean too hot to touch? if it isnt, i cant see it being anything but a problem with the motherboard.

if its not the ram, i'd send it straight back. infact, i wouldnt have spent any additional money on it at all.

amkan13 · 8 Sep 2009 at 16:19

could also be the chipset cooling on the motherboard, a crap heat-pipe that isnt up to the job maybe?

tonym · 8 Sep 2009 at 16:22

Not sure if this has been asked before, but...
Whereabouts is the PC? In a bedroom or a study or what? Is it an old house, new house?
What's nearby to where you live?

Are the poweroff's on your PC regular or can they just happen anytime? I noticed you said you were playing Diablo for 5 hours then it went off, can it go off after a couple of minutes? Does it go off around the same time each day, or is it any time at all?

roop128 · 8 Sep 2009 at 16:38

have you checked the wiring between the on switch and the mobo, could be faulty, this happened to my friend once

Soulmagika · 8 Sep 2009 at 20:37

Right now it seems to be going off after a couple of minutes, even when there isnt anything open, but yes ive kept the fan on it all day and it hasent switched off once.

Edit: my pc is in my bedroom but i'm not sure it has anything to do with it. Its in a quite open space.

Are you doing this on purpose? I can't send it back said i've said that, i know i made a stupid buy but i'm not going to do it again. Ill just have to manage with this.

But yeah hmm, ram? Havent touched the ram ever. Also, my pc has only ever started switching off when i replaced my GT9500 with my HD4670.. when i got the pc it wasn't switching off, though im still not sure if thats it because it just might have taken time to break..

sorry for delay in replies mate, i've been very busy, i noticed you were having trouble with drivers installing. You did uninstall the nvidia driver right? Not meaning to be patronising it's just we all make silly mistakes. Let's cover basics first, as i severely doubt it's ram (i could be wrong but never heard of a case of over heating ram) and the temperatures you reported seemed ok when it shut off so probs not cpu or gpu cooling. You have plugged in all the necessary connectors from the PSU? there should be a 24 pin connector and either a smaller 8 or 4 pin connector that should attach to the top left of the board. Check these are in properly and not loose. I don't believe the 4670 requires an extra power connector so we should be fine there (but check anyways to see if there is anywhere to plug a cable in). Check all other cables are in firmly, you never know you may of un-knowingly knocked something loose. Now if it's none of those basic things i'd try perhaps running memtest86 (another program you can download) to test your ram for faults. Perhaps rebuilding it outside of the case if you feel comfortable doing that as it would rule out a short circuit. To be honest mate, this is an awkward one.

Uuurrgghhh... i knew this would happen.

But when i put my fan pointing at the inside of my computer it doesn't switch off, after i take it away in about 10 minutes it switches off.. doesnt that sound like overheating?

im sorry, where did you say that?

stop biting at people. were TRYING to help you. if the pc is faulty then its not fit for purpose. if its still under garantee then of course you can send it back.

He can't send it back as he has tampered with it mate, open up a pre made pc and that's pretty much your warranty over. Could try putting it back to it's original state but i know that's going to be hard as often they'll wire it up so it's impossible for you to rewire it the same without breaking a clip or something so they'd know.

Also he has a point don't snap at the people that are trying to help you or you'll find yourself with no help at all if that's the way you continue. For the most part we're nice bunch of people here and if something looks like a dig at you it's probably not, normally a simple misunderstanding or poorly worded sentence.

Well this is news, does look like something is overheating, however we now have to work out which bit. might want to pull out core temp or something again and check the temps with and without fan, same with GPU using catalyst control centre. Unfortunately with most motherboards that come in pre made pcs they don't allow you to do a lot so checking other temperatures could be a problem. I would say touch your ram to see if it's hot but if it's the ram that came with the pc it wont have a heatsink on it so probably not the best idea.

how long have you had the computer running with the fan on it? has it not turned off once with the fan on it? Perhaps let it run with a fan on it and play a game see if all is stable then remove the fan mid game and see if and how long it takes to crash. Would be good to monitor the temps whilst doing this but this is only really feasable with two screens or running the game in a window which is annoying. I just want to rule this out as not being a "one off" if it's fine with the fan then crashes after you remove it we can safely say it's temperatures causing the issue.

Phage · 9 Sep 2009 at 09:44

Core temp shows reasonable temperatures, so my guess is that the GPU is overheating. (being the other component changed). Something like this.
http://www.tomshardware.co.uk/forum/page-253404_15_0.html

There is a program you can download called GPU-Z which can record how hot it's getting. Ati tool is another. Gpus do run hot but anything over 80c will probably force it to shutdown.

Is the card seated correctly ? Might be worthwhile just giving it a wiggle to ensure it's fully in.

Sorry for snapping, its just so.. arrgghhh xD.

I had the computer on for about 8 hours yesterday, while the fan was on it. I turned off the fan and boom, in 10 minutes it switches off.
