Problems with Game and PC stability

Hello,

I have been experiencing many crashes and problems with my pc since march. It started with Battlefield 3 where I would always get a crash after about 10-20 mins into the game.

These crashes often different. Sometimes the game just minimised and wouldn't go back, sometimes I would get an "Nvidia kernel mode driver has stopped responding and has recovered" and occasionally I would get a freeze with a sound loop followed by a black screen.

These problems were only in battlefield but now they have to every game, even games like Skyrim. I reinstalled windows but it didn't help. The problem that I have now is that after about 20 mins my wholes system will begin to lag seriously, like at 0.25 fps and my peripherals would start disconnecting and reconnecting (evidenced by the windows sound).

Here are my specs:

Windows 7 64bit (latest updates)
ASROCK Z77 extreme4 motherboard
Mustang 2x4GB RAM (from a friends custom pc off ebay so pretty cheap)
Intel i5 3570k stock clocks and stock cooler
WD Green 1TB HDD
Toshiba x24 Drive
Gigabyte GTX670 OC 2GB VRAM
Antec Trupower 650W semi modular PSU
Creative Tactic3D Sigma Headset

And here are solutions I have tried so far:

Full reinstall of windows 7 64 bit followed by drivers, origin and BF3 only
Lowering GPU memory and core clocks to stock and upping the voltage and fan speed (its definitely not a temp problem)
Updating GPU and Mobo BIOS to the latest versions and set Mobo BIOS to factory settings
Memtest86 on RAM (which showed no errors)
MSI Kombuster (which ran perfectly fine)
Editing registry, specifically setting TdrDelay to 8 (what's interesting is that Battlefield still froze and any sounds playing just echoed away as normal but the game still minimised, it just froze for longer)
Cleaning out dust from system and reseating GPU and RAM
Ran OCCT test for PSU and it showed the same problem as in games

I hope someone can help me out with this problem or at least help diagnose what is causing it. Many Thanks

It sounds to me like your RAM isn't healthy or dirty power from the PSU. Specially if you have lowered the GPU clocks to test that. BF3 is very GPU heavy, Skyrim a bit less so to put that in perspective for you

I was suspecting my PSU because I had the same problem about 7 mins into the OCCT PSU test, I've had it for just over a year now. I tried memtest86+ for the RAM but had only enough time for one pass with no errors. Will try to leave it on for longer.

I will try this. Thanks for the suggestion and thank you to everyone for replying so quickly.

Ok so I went on Intel's website and it turns out the Tcase for an i5 3570k is 67.4C meaning it begins to throttle at temps above that right? I took out the GFX cqrd and my games ran well and OCCT ran stable for 20mins until I stopped it myself however the CPU temps went as high as high as 84 on core 1 and 2 and 79 on core 0 and 3 (on a stock heatsink). I know I said temps were not the problem but maybe they are causing the cpu to throttle and affect the 670?

i have a 2500k but i do not think it throttles so low since your thermal ceiling is 100C. those temps are pretty bad. are you overclocked on the CPU?
on a positive note your cores all seem to be running at close to the same temps(an issue with the 3rd gen chips and is only solved by delidding).
if you want to test CPU temps run prime95

be ready to shut down this tiny program quickly if temps get to 80C, if you hit that temp something has to change.
my rec:
http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
it is $20 and can get you 4.8MHz easily

on another note i have noticed in the past when a powerful graphics card is installed some CPUs will self throttle to only use what power is available

Yeah I was looking at that cooler because it seems great value for money. So I'm guessing its either CPU temps, dying PSU or bad GPU seeing as when I take the GTX670 out my games run fine on the integrated HD4000 (at least the ones that actually can run on it like Skyrim, SC Conviction and DEHR ).



Don't...

at this point I would want to test the graphics card in another known working computer. I would also want to get a new power supply and see if it works in there (where ever you buy it see if they can test to see if it is working while your there). Which ever of these is easier is the one I would go with. See if you can find a place to get a power supply and return it if needed or maybe you have a place that will test those both for you quickly and cheaply around.

everything runs fine without the graphics card in right?
