I previously posted something in the audio forum about this issue I've been having because the symptoms were audio at first. Here's that topic: http://en.community.dell.com/support-forums/laptop/f/3517/t/19531424.aspx
Dell XPS L502X
Intel Core i7-2620M CPU @ 2.70 GHz
8 GB RAM
Windows 7 Home Premium 64-Bit OS Service Pack 1
NVIDIA 525m Driver Version 331.65
Basically a problem I've been having, most frequently when attempting to play "Dead Space", is that at random times my computer and the game will freeze, a buzzing sound will loop, and nothing will happen until I manually restart the computer. At first I thought this might be an audio issue, so I reinstalled and updated drivers, which didn't help. Then I thought it might be a heating issue, so I cleared out any dust, which helped my computer heat, but didn't solve the problem.
I discovered that the problem is with my video drivers when I was running Dead Space in a window with task manager open (to see if it was a CPU issue, it wasn't, total usage was between 35-50%, with one random spike at 65% when it froze for a bit, which I assume is the computer trying to restart the drivers), when the freezing happened, but my computer recovered and kept going (which has also happened). When this happened, two subsequent notifications popped up saying something along the lines of my Intel Graphics Accelerator Drivers and my NVIDIA Kernel Mode Drivers had stopped responding, but had recovered. I'm assuming that when the computer stays frozen and requires a restart, they don't recover.
Does anyone know how I can fix this?
Hi Mike, sorry to disappoint you, i don't have solution, but exactly the same problem on the same computer.
So i wonder if you solved it somehow? I was reinstaling and updating drivers in weeks now and don't know what to do anymore.
I can't play any of the games i got, some are not that new even.. and it's really frustrating.
I have witnessed the same issue... for me the problem was upgrading my nvidia beyond the Dell drivers....
The Dell drivers are a year behind the Nvidia reference drivers... What I did is clean install back to the last Dell drivers.. DO not install the 3D experience and just the drivers... and things seem to be stable....
Did you upgrade the drivers from nvidia site or dell (support.dell.com) site?
