What is causing restart of computer overheated card or driver??

[Mk1980]

Could be restart of computer caused by extreme overclocked core of my Ti4200 128Mb from Gainward?? 310 core 570memory,, only in some games like MotoGP and Warcraft3 it have happened, not on Serious Sam after 4 hours of play?? Are these games extreme overheating my card, especially using vertex and pixel shaders on MotoGP??? or its only incompatibility little bit,, Whql drivers 29.42 before now 30.82whql,, thanks for your advice.

What exactly is it doing? Does it just shut down right out of the blue?
Does it shut down after a certain amount of time?

When I put in my Ti 4200 my PSU (Aopen 250w) started being a hair dryer on me. Then after about 5-6 hours of being on the video would die, along with the K/B and modem. The sound card would not.

Nothing would respond. No mouse movement, not reset button, I even held my finger on the Power button for well over 15 seconds. I had to completely remove it's life source entirely.

So I upgraded to a 300w PSU and it's all good now.

So really, there are a number of things that could be causing the reboot. Each of those things may also have a number of contributing factors. If you think it's the verclock, so then just set the settings back to the normal speed and test it.

I would say your problem is most likely heat. Older/poorer case designs and poor ventilation often contribute consdierably when you try sticking modern gfx cards and CPUs in there, and rebooting is a VERY big sign of too much heat. There are plenty of other things to consider though. It could be a sign of faulty hw, faulty drivers, corrupt files, heat probs, or of course just a sign of M$ incompetence .

First I would set all of your components back to their defaults (no o/c), including running safer BIOS settings (slower RAM timings like higher CL etc). Keep it like this and see what happens. That should help to rule out o/c as the cause and also heat (never fully trust o/b sensors) providing your case cooling and PSU are up to the job.

Playing around with different driver versions can help. Never use beta versions (esp when trouble shooting) and try both chip and card manus' websites (eg nVidia & Creative). Use the most recent non-beta driver unless told otherwise on the manus' website and rem to check for any incompatibility info. Ensure you removed all traces of previous component drivers when you upgrade hw.

Re-installing the OS should be enough to eliminate corrupt files but I'd also rec a low-level scan of your harddisk inc surface scan. A fresh install is more likely to work happily (use a different source CD if poss) but means you have to reinstall eveything!

That leaves M$ incompetence which nobody can solve ... and of course faulty hw. Take out all unecessary components, NICs, sound, modem etc. Just leaving your PSU, CPU, mobo, RAM, gfx card and boot HD (yes unplug both IDE and power cables from all non-essential IDE). If you still get BSOD/instability then you'll have to swap each of these essential components with ones you know work (friend's or friendly local shop). Bear in mind there's a high probability that you damaged a component if you o/c, just because it's stable doesn't mean you aren't shortening its life or stressing components in a way they weren't designed or tested to cope with. I always prefer to be generous and back off a few steps when I find the limit, and I never up the voltage. Either way you'll find o/c means your warranty is voided.

Absolutely and the easiest way to check is to put your card back back to stock speeds and see if the problem persists. Spontaneous reboots are a classic symptom of a video card core that is clocked too high.

I would say your problem is most likely heat

True but remember that this problem can occur even without excessive heat.

I had the same problem...computer rebooted itself out of the blue while I was playing warcraft 3 and other 3d games. I thought that it was a heat issue so I tried many things...got my temps to a very respectable level. it still rebooted... then i played around with bios settings, turning some things off and setting everything to default settings or lower...still rebooted randomly... Now by this time I'm getting super pissed.... I checked my motherboard monitor settings and found that my 5v rail was pretty low...4.78v at idle. I don't know why I never checked earlier...anyways to make a long story short.. I put in my power supply from my other computer and now my 5v rail is at 4.88 at idle and my system does not reboot itself anymore at least as far as I can see.

Sorry if that was wordy or confusing...but check your power supply...you'd be surprised how a crappy ps can effect your system. And I thought I had a good PS..it came with my antec case. I've also overclocked my 1.33 Tbird to 1.51 and set most of the bios settings tweaks on and it seems to be running stable.

On a side note, up until recently I had a Thermalright Sk6+60mm y's tech fan and my cpu was a rediculous 52c at idle...i swapped it with a 12 dollar volcano 7 hsf and it is now at 42c with the overclock and all the tweaks. Heat definitly played an issue because my computer would hard lock when it overheated. It would reboot itself when the PS couldnt handle things.
hope this helps.

Thanks for advices,, I will try all, but now I havent restart on 5 mhz downclocked my ti4200 to 305\565 which is giving me about the same score in 3dmarks like before, so I think its enough frequency for Geforce4 to get good results

 

[Mk1980]

that 5V thing is on my mobo detecting on 4,68 which is lower like your before, and I dont know what is this detecting and about

 

[shurato]

4.68 is really low at idle...its possibily and a probable reason of your random reboots when your system is stressed...try running 3dmarks and seeing if your system can run it without it rebooting automatically. It might be time for a new quality PS if you plan on overclocking your computer or video card.
