Yep those drivers can really **** stuff up.
Here's a nice story.
I installed a new CPU. Put my own well third party thermal paste on (you can NOT run any CPU without this.
I started up a game called Dirt 2. Well it ran fine for about 4 minutes of playing and would crash and that was very new.
So I thought "what could cause this--well what did I change: CPU".
So I took it out and reapplied thermal paste.
No change. I kept getting some strange error about "Graphics driver crash" but i'd just updated the video drivers after i'd installed this 775 socket quad core CPU I'd paid $125 for.
I kept reapplying thermal paste five or six times and eventually put too much and killed the CPU. It never did overheat.
I kept thinking it was something I had changed.
Put back in luckily still working dual core CPU and got the SAME ERROR.
Yeah that sucks so it wasn't the cpu. It was that damn buggy new driveri thought I wanted. And lots of people complained about crashing.
Itwas Nvidia famous 320. Something drivers. They were really bad.
Pay close attention to driver updates and don't rule them out. Sometimes they cause major issues that aren't your fault.
I since upgraded CPU + motherboard to support the new processor, to Intel Xeon 1230v3 that idles at 20 watts which is probably close to mobile CPUs. The old one used over 50 watts at idle.
