Well, in my last thread, Random Rebooting, I was having a problem with my computer randomly restarting in the middle of games. I tried a bunch of different things to fix it and nothing helped. I pulled out various pieces of hardware and swapped them out with different parts to determine the problem, the only things I havnt tried yet were the PSU, motherboard, CPU, and graphics card. I have pretty much quit gaming for now, with school just starting, so I temporarily gave up on the problem.

Today a new issue showed up. I am continually getting popup windows with the nVidia logo on them that say:

Problem Report: The NVIDIA System Sentinel is reporting that the NVIDIA-powered graphics card is not recieving sufficient power.

To protect your hardware from potential damage or causing a potential system lockup, the graphics processor has lowered its performance to a level that allows continued safe operations.

I am not just recieving this popup once, it will pop up 10 times at once, I will click them all off, and then a few more will pop up. I have clicked it off 18 times just turning on my computer long enough to log onto firefox and type this post.

Does this indicate a PSU issue or a graphics card issue? I have an old 450W in the attic I can dig out to test, but the only old AGP video card I have laying around is a GeForce 2 Ti 64mb. I have already opened up my case and made sure all the power connections are tight, unhooking them all and reconnecting them, and that did not fix the problem.

It is a 6600gt. The 6800Ultra can run just fine on 400W though, 500W is really only important if running two cards in SLI, and even then not necessary. My system ran just fine for 6 months before the problems began, so I am beginning to thing one of my parts is failing.

I am running a 6800gt on 230 watts right now. I would say get a good PSU from someone like OCZ, Antec, Zippy, enmax, PC power and cooling or seasonic.

agreed, im running a x800 XL on a 350 w psu. even though x800's take less power and use less heat, its still supprising it runs. what really matters is amperage. 16A runs this card fine, for nVidia 6xxx series i recomend at least 19Amps. this is probally his problem, when i had a 6600 gt i had the same thing, until i upgraded PSU amperage, not a problem with it, still no problem with x800 XL.

The main thing is this is a recent problem though. I havn't changed much in my system in the past 6 months, and until recently, the computer tore through anything I threw at it. So if it is a problem with the amperage, it is due to the PSU going out. Asusprobe only shows voltage, not total amperage, is there any software that I can download to show me the amperage my PSU is putting out?

According to the box, my 450W PSUs rated output is+ +3.3V@26A, +5V@45A, +12V@28A, -5V@0.8A, -12V@1A, +5VSB@2.5A. This should be more than sufficient for my system unless it is not working properly.

my second guess then is that resisters on your motherboard or PSU are starting to sagg. if you start to have grafic corruptions (too abnormal for common artifacts) its definatly your mobo. otherwise i say throw a new PSU in there. no nessasarly a 500 watter either, just a new one. rosewill are about the best brand, antec is a bit overrated and over priced. there is no program you can download for rading your PSU amperage, you would need and actual, physical sensor on your wires or motherboard. if you can splice a few wires you can but a voltage/amperage meter at a hardware store. BE CAREFULL!!

My BFG GeForce FX5500 says right on the box............. "Minimum PSU 250 Watts" That 6600 probably needs more than what you are giving it. I bet my left nut on it.

Bad idea. The box for this card says minimum 300W, I have that beat by 150W.
