nVidia GeForce 7300GT 512MB, machine hang problem

I have recently purchase Inno3D nVidia GeForce 7300GT 512MB for AGP slot. I have remove my old GeForce GTS2 card and installed my new card. After then I installed my new card drivers from manufacturer Cd. I have installed several games including Need for Speed ProStreet, Need for Speed Carbon, Evil Genius, METAL GEAR SOLID2 SUBSTANCE, F.E.A.R. , F.E.A.R. Extraction Point and others.

Now the problem is that when i am playing any games listed above my machine get hang after several minutes or hours. When playing game before getting stuck my display is gone to fuzy, i mean the currept display picture and my machine not working any more. I try to close game by pressing Ctrl+F4, Alt+F4, Ctrl+Alt+Del, Ctrl+Escape, Win Key, but none of them works. So i have restart via restart button :(. I have reinstalled my card drivers two times. Its the latest drivers. I have check GPU temperature and its 50C. My OS is Windows XP Pro with SP3.

Please help me, i can't even play a single game with this new card. My old card is working fine when playing games, but it isn't capable of playing new games.

My Machine Configuration is below,
Processor = P4 2.0Ghz
Motherboard = d850MV with latest BIOS update

Did this card require extra power? 480 watts should be ok but maybe one of your rails is failing. Why not run some severe burn in suite at the card and see if it doesn't do the same thing as it does when playing a game. Everest professional would do it or hot cpu if that is  still around. Finally, is the fan spinning up? Anyway, if it folds under this kind of test then it is time to RMA the card.

Thanks for reply

Well as you said, here is my test result. I notice that the CPU temperature is going high about 67C.

Oh i forget that my AGP need extra power. Its the same as like HDD or CD-DVD power clip.

So the problem did not recur when you stressed the card. How long did you run the test? 67 c is not ridiculously high for this card. But the slowdown threshold for this card is 75 which is not too far away. Is this a version with a fan. You might want to pull the card and make sure the heatsink is not loose. If it has a fan, open the case while stressing the gpu, and make sure the fan spins up nicely. Is there another card immediately adjacent to it? If so, can you move it one slot down. This thread has an extra cooling option described. http://forums.nvidia.com/lofiversion/index.php?t30325.html Also check the amp's output on the cards 12 v rail that gives the extra power. Everest should give you this. if not then you can test with a voltmeter. Maybe your PSU rail is running weak.

the test is about 5 min.
67c is processor heat not grafix card. in whole test the grafix card heat is about 51c-52c (the green).
Yes, this card is with fan picture is below
Yes, there is another card after agp, but it have a gap like ||  ||     ||.first 2 are the usb and tv tuner and the last one agp.

Here are some images that might help you to figure out the problem. One more thing that last time i have play DOOM 3 with Ultra Setting in 1024x768 resolution, and my machine is working fine. The i play Metal Gear Solid 2 for about 1 hour and my machine still working fine. Anyway here are the pictures

1024 by 768 is fairly tame now in terms of vid cards. See if you can get everest to do nothing but run the gpu stressor in loops. Ideally, we need a tests that will crank it continuously all night if need be. http://www.ozone3d.net/gpu_caps_viewer/index.php#intro    http://freestone-group.com/ it is about 4 down or so
Here are a few more. Pick one that cranks it for hours on end. Also did you check and see if the fan is spinning up properly.

I am still not forgetting about the possibility of this being your Ps though.
"Problem: Brownouts, weird errors, or a dead PC since a new device was added.

Solution: A common problem with a premade computer from a major manufacturer is a power supply thats just good enough for the devices that shipped with the PC. Add a new multicore processor or a hot new video card or two, and you might find that the computer works erratically under load, if at all. If your upgraded system dies every time you start up a taxing game such as F.E.A.R., for example, you might need a stronger PSU. And if your PC doesnt work at all after the upgrade, either the new device is defective enough to cause a major electrical problem, or the total wattage your PC now requires to run is more than the PSU can supply.

Also, make sure that your PCs fans provide enough airflow. As mentioned above, a hot power supply doesnt provide as much current as a cooler one, all else being equal.

Note that your power supply may be ready and willing to supply more current to devices that run on 5V or 3.3V power, but that doesnt matter if the 12V devices overwhelm the 12V rails capability. Most power-hungry devices, from the CPU to the graphics card to hard drives and DVD/CD drives, require 12 volts to run. For this reason, many servers start up their hard drives in a staggered sequence so that they dont overtax the PSU. This feature is possible with SATA (Serial ATA) hard drives, but as yet, staggered spin-up isnt commonly supported in desktop PCs."

So, if you happen to have a more powerful PS laying around to swap in it would not hurt once you have eliminated heat as the issue.

I will download and start the tests as soon as possible, and will post the results.

Yes, the fans are working properly. there are PSU fan, Processor fan, AGP fan. I have noted that all the fans sucking air inside PC case, there is no fan that can push the air out side from PC case. So i will add FANs for that purpose.

I have build my machine my self, from a single part to complete machine. The most recent thing is PSU (460Watt). Its a CoolerMaster eXtreme Power Plus.

I will also post my machine pictures as soon  as possible.
Well, in the meantime that is an important point. One of the links or threads I posted made the same point of making sure exhaust fans were in the picture or not accidentally reversed.

Today i open my PC case, mean one side open. Then i play DOOM 3 on Ultra settings about whole day and wola, my machine didnt hang :)

Since here (Pakistan) weather is cold, i noticed that after removing my case side, the temperature is only about 40C. But when i turn on heater for my room, i noticed that the temperature is increasing to about 50C in just 5 minuets.

Also i run 3dmark and other benchmarking utilities for a hour and my machine didn't hang. So i think the problem is HEAT, not GPU or PSU. But i will see for next two day for final decision. Also i will post my benchmark results.
What temp figure is that. Board temp? Ambient temp? In any case, having no fans that push air out should be attended to. My Ps has an exhaust fan. And my cpu has a fan that I added to blow into the stock shroud plus the shrouds fan to give an extra push.
SiteElfAuthor Commented:
The temp that increase form 40c to 50 is GPU temp. For processor temp when running benchmark the processor heat is increase from 50C to 75/80C. But in normal case the processor is not much produce heat.
Ok, those are all reasonable numbers for temperatures. Clearly adding an exhaust fan or two will help when summer comes. So have you tried an all night stress test on the gpu. Also you may want to consider the Omega drivers for nvidia if the porblem recurs
