alright, one of them was inconclusive and the other had svhost (another windows file). Which games are you playing when it crashes. I had all my blue screens fixed.
I had a couple of virus on there because I noticed some weird drivers and went threw a virus scan on this forum. You can click on my name to find that thread post.
What I would suggest is that you get HWMonitor so you can monitor your cpu tempatures. I though i might be overheating so I was monitoring my temps and cleaned out my cpu and videocard. Alot of dust came out, but all in all my tempatures were the same after the fix.
The fix for me end up being reinstalling nba 2k12. That was the only game causing my BSODs and after being declared clean from virus I reinstalled it. No more BSODs. So I guess the install got corrupted somehow. Before you do that though check your game files on steam.
Right click on the game thats crashing you, goto properties, local files, and verify integrity of game cache.
Since you did a fresh install of Win7 all of your system files should be clean.
If you still get crashes after all this you might want to start checking out some of your hardware. Have you ran through a memory scanner to see if any of your ram sticks are going bad? A couple months ago I was getting a bunch of BSODs (not just from gaming) because I had a bad ram stick. Wouldnt even get through 1 Pass on memory scanner.
