I bought a nice PC (a used one) few days ago. The guy who sold me the pc told me to install Windows 7 Ultimate 64bit because the current one was installed a long time ago. Before I did so, I played NFS Most Wanted 2012 for an hour or so and had no problems. After I installed the win 7, I installed CoD4. I played the Multiplayer for few hours and crashed for the first time. After that I couldn't open MP, it said codmw stoped working, but I could open SP. Then I realised I had no GPU driver (shame on me) so I downloaded the newest from their site (I made sure that I download the 9 series). After I did that, I installed Bioshock Infinite, played and finished the game on medium graphic options without crashes (with a few lags occasionally but nothing special), that's around 6-7 hours of gaming. So I installed Bioshock 1 and 2 and there the crashes continued. 1st time bioshock 1 crased I couldn't open it anymore (just like cod4mp) so I deleted it, and now I play bioshock 2 and it crashes in mid game or sometimes only few seconds after I load my saved game. After every crash I am forced to restart becuse, you know, the screen freezes and sound gets weird. And here I am now, desperately asking you guys for help

I downloaded CPUID HWMonitor to watch over my CPU and GPU temps.

How to speed up your game, make a gaming user do 1 screen and run nothing no tags, no Intel(R) Turbo Boost Technology Monitor, just maybe no icons, close every window before running the game and run the prersonalization in >High Contrast White<

i hope this helps
