Ok, I've seen a few threads like this with my problem, and I've tried all the solutions I've seen for the problem, none I have tried worked for me, here's my problem:
I recently installed a Geforce GTX 260 in my computer. I loaded the proper drivers and everything seemed to work fine. Whenever I try to play any slightly graphic intensive games like Left 4 Dead 2 for example, a few minutes into the game my monitor screen goes black and the audio loops then the system shuts down. I've tried everything, writing over drivers, completely uninstalling drivers, changing out my power supply. My computer won't shut down any other time though, like if I'm playing a non-graphic intensive game like Terraria, it plays on just fine, or if I'm just browsing the internet. Here are my current specs:
ASUS M4A785-M Motherboard
Windows 7 Home Prem.(x64)
AMD Phenom II X4 955 3.20 GHz processor
8 gigabytes of ram
D-Link DFE-530TX Network card
Cooler master 550 watt power supply
And the Geforce GTX 260
The current drivers I have installed for my video card are the NVIDIA grapics driver 295.73 for the GTX 260.
I had a similar problem when I had my GTX260 in my old PC. I didn't realise for a long time that the power supply I had did not have sufficient amp requirements to power the graphics card. It was okay for the first couple of months, but once the efficiency degraded it would not power everything properly. (Crashing, artifacts) I ended up getting a decent power supply instead.
FYI: The GTX260 requires a power supply capable of 36amp on the 12v line for the whole system (I realise that they sometimes overstate this figure, but it is still a good guide to go by)
Ok swifty, I've just finished setting up your solution. I've also installed the EVGA precision program and set my fan speed to 100% in case it is an overheating issue, I'll test it out and get back to you guys, thanks!
I do not believe that solved my issue. I did a test run playing some Left 4 dead 2. I was able to completely one chapter, I then exited the game and checked the status using EVGA precision, the GPU was up to 110 degrees Celsius while I was playing, WAY to hot I think. So how else should I cool down the GPU besides setting the fan to whirl at 100%?
i never had my fans at 100%........ if it's getting that hot the fan isn't spinning or you need to pull the heatsink and reapply thermal past and clean the dust from the cooling fins or all three. how's the airflow through the case ?
Yup, me and my dad took it apart and cleaned it, it was pretty dusty and the thermal paste was dry and cracked, so we cleaned that off then reapplied new thermal paste, now it runs super cool. Thanks for your help guys!
