Maximum PC

I used to have my games randomly minimizing before and they stopped for about a month and they just started again yesterday. I was playing Portal 2 and it minimized about twice in the 10+ hours I played it (beat the entire game). Then today I have played Skyrim about 2 hours and it started crashing randomly. crashed then was fine for about a half hour then it started crashing about 5 times at least every ten minutes then stopped then started again and I tried saving but that crashed the game... I had saved a few times before that. It never ever ever ever ever etc. crashed at all before I reinstalled windows on a new SSD. Is it maybe a driver or software I forgot to install? As far as I know everything is roughly the same as before I reinstalled windows on a new SSD. Please help! Thanks!

I have done EVERYTHING!!! You name it! But... I didn't realize Kaspersky can minimize your games if its not set for game mode... so that has fixed it! BTW My max CPU Temp under Extreme load is 55C (Water cooled) and my GPU max temp was 75C (fan cooled) under Extreme load. Thanks for the suggestions!

I have been having crashing problems with random games, I'm pretty sure it has to do with the games requiring too much power or heateding your CPU or maybe your graphics card?

It rarely happens now. I still get it every once in a while but rare. Could it be the game I am playing? None of my temps pass 50C.
