Odd computer freezing/overheat issue

By Sudoka ·
Well, here is the strange thing, My computer has plenty of fans. Ten inch fan in the side, a fan on the mobo itself, a fan on teh back and a fan on the front. The issue is it's still overheating (I guess). It happens a lot more while I use Windows than when I use Ubuntu.
The other odd thing is that I don't see anything that would cause this. The case is an Enermax uber-chakra case. Now I'm not very familiar with cases but I assume the more holes the better?

Now what is your suggestion on this? Should I get a new case or is there something horribly wrong with ym computer?

I am not overclocking, and my heatsink is the default intel heatsink.
if you need specs I will be happy to provide some.

So long as

by Jacky Howe In reply to Yes

the modules are from the same maufacturer and it is the same type, all is good. Use the link that I provided to test the memory with. If it tests out OK try swapping slots. Also run the System with the side off so that you can see the CPU fan. Check it when it freezes to see if the fan is working.

Think it's the PSU?

Well it's a 750 watt PSU. The exhaust is about as warm as the exhaust from my graphics card. I can't really remember what the PSU make and model is though.

Well, you may need to find out.

Thing is, a quality PSU will work better. Also, that is the peak wattage, so if you can find out what the normal operating supply is, so much the better.

Then, you need to find out the wattage required by all your components. You should have a good margin between what is required, and what can be supplied.

Is there any way I can find out the power supplied and the power needed with a program?
And if it were the issue with the PSU being lower end, the computer should not turn on at all since it doesn't have the needed power. Right?

Not exactly

by Slayer_ In reply to How?

If for example, your video card switches to 3D mode, it will require more power. If you ran Vista on a pre low power 3D mode card, it would switch to performance 3D and use the maximum amount of power all the time (ouch).

Also, some PSU's, when they get warmer, like under load, they start to falter.

You could try running your System with only one Video card and see if the problem persists.

Prior to my upgrades, I was running a 9600 GSO with 786M of ram in the card. Recently I got a suped up 260 gtx (The maxcore one form BFG with 896M of video ram). Even before I got the card it would do the same full system freeze.
When it freezes, the fans are still running,but there is no HDD activity.
My PSU, well, I can't really remember too much about it, but I'm pretty sure it's not exactly a high performance one, but it has 750W. That wattage calc told me I need a little bit less than 500W, but I'd still like to have overhead. I could consider getting a new PSU, since the exhaust temp is probably the same as my 260's.

Is your 750 rated to produce high voltage for a long time?

by Slayer_ In reply to Did that before.

Some cheap PSU's can only spike up to high voltages for short times, but will overheat if it stays high for too long. What brand is your PSU (In case you said it, can you repeat it, thanks)
