Problem with G72Gx graphics card

Hi there folks,



I have an old G72GX with the 260m graphics card. The problem is that after gaming for a little while the game gets like 4 fps all of a sudden. The idle temperature is 64C. Even after playing minecraft for 5 mins it starts lagging like crazy with very few FPS. I tried a windows reinstall but didn't solve the issue. I also have to restart the computer to get it back to normal, then after gaming for 4 mins it laggs again, and the computer gets slow. is the graphics card most likely broken? Anything I can do to test this?



Thanks

The idle temp doesn't matter as much as your peak temps while gaming. The graphics card will throttle back its clocks when it gets overheated, so that may be the cause.



The G71 and G72 have been known to have a less-than-optimal cooling design.



Are you sure your fan and vent areas are clean? Is your fan spinning at its normal speed and not making any bad grinding sounds?

I tried using compressed air in the fan and the idle temp went from 64C to 62C. I ran furmark extreme edition for 2 minutes and the temps were 95C and rising. The fan started getting louder when the temps reached 82C, and when the temps reached 94C it got a little louder aswell. No weird sounds from the fans.

Yeah I'm not surprised about furmark but what are the temps when you're normally gaming?



Are you out of warranty? You may need to consider reapplying the thermal paste on the GPU (and probably CPU).

I installed Black ops, and with the lowest settings I only got about 13 fps. Temperatures were around 73C. In Minecraft it also plays a bit choppy, every 3 seconds it would freeze for like half a second. And I do not have any warrenty, I did try changing paste on the GPU, but no real change, it also took me 5 hours.



Edit: If I restart the computer I am able to play black ops with good fps, but after some time it just goes down to really low fps, the temperatures don't really go up that high for CPU either.

Try running memtest86+ since it sounds like your temps aren't the problem.

Try this.



Download HWiNFO32



HWiNFO32 Download



Open up the Sensors panel and let it run.



Play a game until the FPS throttle down and then report back with the CPU and GPU temps (All of the GPU temps please.) in the MAX column.



This is a good place to start.



I had a G72GX for a year, had it overclocked within an inch of its life and dealt with all sorts of temperature issues. Maybe I can help.

Running memtest86+ now, it's about 30% done. There are 92 errors and many red colums. Not sure what any of it means.



Here is a picture of it so far

Ouch, you shouldn't have any memory errors. Turn the computer off and try pulling one stick of your RAM out at a time to eliminate the bad one. Run memtest until you get no errors with the remaining RAM. Then replace it with a new one.



I hope that solves it for you.

Thank you so much, never really thought it could be the memory.
