I'm at work now, so I'm not able to verify a couple of things... but let me mention that last week I resolved a major problem/headache and I'm starting to think this was related.
I'm almost sure that BSOD occured before resolving this problem.
OK, the problem that I had and had learned to live with... Whenever I opened Windows Explorer, it was always give me "Not Responding". It would eventually come back after like 5-10mins. If I attempted to close window I would have to hard reset PC since PC would eventually become non-responsive.
To resolve this problem, I was always looking at startup applications or what software could be causing this problem... this problem always appeared to be random.
Solution: I currently have 2 DVD drives and always had 2 CD's with games Crysis & AOE III inserted. The problem was with game Crysis. After taking this game out of DVD drive... problem resolved (Windows explorer opens fine now). Since I inserted & tested other games on this same drive, something is wrong with Crysis DVD or maybe some type of encrytion with this game and windows explorer does not read properly. I had checked to see if I had latest firware for DVD drives and I had latest firmware. It never really occurred to me that this particular game could be the cause of this... and belive me... This caused me alot of trouble & headache trying to fix this... and eventually gave up and tried to live with... But now, since this is resolved... this had taken a major headache off my back.
Now, back with BSOD. This weekend I played all weekend and did not get any BSOD's when playing COH... but the jury is still out if the Crysis game was the root cause in getting BSOD's. I suppose, that while playing COH (I don't need to have COH game in DVD drive to play COH) game attempts to read DVD drives ? and since PC was unable to read Crysis DVD game... it became unresponsive and I get BSOD... ?? I would get BSOD's like after 20 mins into the game... and it did not occurr in every game. I would like to continue testing/playing before I sign off on another major headache..
BTW, sorry for the long reply
