OK, ive just built a new PC, heres the specs

500W PSU
120GB HDD
40GB HDD
Creative Sound Blaster Live!
AMD Athlon 64 3000+
Sparkle NVidia 6600GT
512Mb RAM

Im having a problem. Games have just started crashing on me, battlefield 2 used to work fine, now i can play it for a minute or two, then it crashes my computer completely (not to desktop, it does a straight restart). This is the same with 3DMark05. Again, it used to work fine. I dont think its an overheating issue, although i have no sure way of finding out. Also, i have recently re-installed directX 9 (these problems seem to have been occouring since installing UT2k4), but reinstalling DX9 doesnt seem to have helped the problem.

Any ideas would be welcome.
 
actually, im getting to think this is a heat issue. The nights here seem to be getting hotter, and it hasnt happened all day.

I cant install the latest BIOS - no floppy drive unfortunately, but i do have latest GFX card drivers

Just tried again, 3D mark 05 crashed again. Seems to be a minute or so in. The screen went all like, blocky, but not like usual pixellation. There were a few pixels in strange colours. Thats really the best way to describe it. Anyway, i will try again tomorrow, and try that motherboard monitor you posted.

Thanks, slug
 
Yah, it really does sound like a heat problem. That pixelation you describe is a good indicator. I'd fix your heat issues asap, or you are going to damage your hardware (if you haven't already).

Good luck!
 
ok, ive come to the conclusion that it is a heating issue. This time, 3dmark05 got onto the 2nd test, then bailed near the end of that, this is in the morning here, when it seems to be a bit cooler than at night.

So then, whats the best cooling method?
 
But the problem is, at this point we don't know WHY you are overheating. (Let alone WHAT is overheating).

It may be just your video card, but your rebooting sounds like your CPU is the guilty one. That pixelation has me confused. We need someone with more experience to give some imput.

Best case scenario, you add more (or more powerful) case fans and that fixes the problem.

But it is possible that your current CPU heatsink fan needs to be re-seated with some new thermal paste. If you have never done this before it can be tricky.

And if you are going to go that route (removing your CPU heatsink), you may as well plop a better heatsink on there while you have the stock one off. A good heatsink on the CPU makes a HUGE difference.

There are many good makers out there these days. Are you using a socket A motherboard? Check out the Zalman fans. They are pretty good.
 
By the way, what bios are you are running? That is another possibility worth looking at.

You mention that your vid drivers are up to date, what about your motherboard drivers?
 
nope, its a new socket 939 one

ive noticed a couple of times when it has crashed, the monitor has gone into standby, but the sounds still work for a bit, then it crashes. Also, after crashing, it seems to take a little longer to go through POST than it does normally. After crashing though, ive looked through my BIOS, and the CPU has been running at around 50-55...
 
Do you mean BIOS version? Im not sure, i'll reboot and find out for you.

As for the VIA 4-in-1 drivers, there doesnt seem a new version for them out...
 
ok, just taken case side off, it feels pretty cool inside there. Also, ran 3dmark with it off, it crashed (again). Felt my graphics card's heatsink. It was warm, not hot or anything. Im starting to wonder if it is actually a cooling problem....
 
I'm starting to agree with you. If your CPU is only getting to 55c, that is nowhere near hot enough to be shutting you down.

There are those in this forum who can help, but they are not a jedi like I am. You must turn to the dark side, as I jedi can not teach you what you need to know...

In the meantime, I would run a diagnostic on your hard drive, and on your memory to rule that out. Go to the Windows OS section of this forum, and have a look at Rick's sticky about getting windows to work. In the first post he describes how to check HDD and memory. I think the best thing to do for now is just start ruling things out, one at a time.

P.S., if you are running an old bios..... it could be as easy at that. :eek:
 
ok, thanks for your help

Ive also posted on the nVidia forums. It seems that the 77.72 drivers can be a bit buggy (or apparantly so anyway) so i waiting from a suggestion from there.

Thanks again, Slug

BTW, approx what temprature would cause a crash in the GPU and CPU?

EDIT: Theres new nvidia drivers out (77.77), im gonna try them now...
 
It depends on your motherboard settings in most cases for when it will auto shut-down, but I think 70c is getting to the danger point. I get worried when my CPU reaches the 60c mark.

For GPUs, I am learning first hand that they burn a lot higher. Depends on your card of course. Mine is a 6800GT, and it runs at 60c idle, 70c at full load. Yeeesh.
 
just been stress testing my CPU with prime 95, its running at about 61-63 - fan running at around 4000RPM. Its been running for about 50 mins now with no errors
 
ok then, just installed rivatuner for debugging purposes (just so i can have stat logging)

Basically, under load, my GPU is running at 66 degrees. Core clock under load is 501.43 and the memory clock is 1002.38. Before i started 3dMark05, the core clock was 300.86 though, and the temp was 49.00
 
well, it seems to have sorted it :)

Just run 3dmark, no problems. Thanks to you two for helping me sort it our

I'll be back if it occours again...

Thanks again, Slug
 
I don't think it was causing overheating. What it does is slow the cpu down a considerable amount when you are doing simple things like browsing the net. When playing a game I think it kicks in sometimes when it thinks there is not much going on, causing the game to crash. In other words, it's not perfect.

If you do use it though it will lower your cpu temps by a considerable amount, maybe five degrees or so. It might not cause a problem while playing games for everybody, but it did for me. I shut it off, no more problems.
 
hmmm, battlefield 2 crashed twice last night. Diagonal bands appeared across the screen once (in like greys), and once, it froze and some pizels were funny colours

Just tried map editing in UT2004, a simple room with a light and playerstart, and UT bailed out after a few seconds, maybe 30secs, if that. Once with the diagonal bands, the other time it just crashed. The second time though, when my PC was booting, it got stuck at the graphics card info (before you see the BIOS screen and it detects drives etc)

i think turning cool n quiet off has helped, but not completely solved the problem :(
 
ok, just run an openGL benchmark. Crashed quite a way in. Just froze, then rebooted. I have already tried this benchmark before turning cool n quiet off, it crashed again, on the same benchmark as what this crashed on. Its just this time, it crashed earlier on the test.

Any other ideas anyone? :(
 
ive run prime95 for a while with no errors

Anyway, ive just installed some modded drivers (xtreme G ones i think) so im going to see if that solves anything

TBH, it seems more stable so far.....
