Skyrim Legendary Edition crashes

[J20Hawkz]

This isn't the games problem it's a problem on my end.

I recently made a thread asking if I could run Skyrim on my pc. Well I bought the Legendary Edition and it runs absolutely fine on low to medium settings and low to mid resolution. My problem is that 40 - 60 mins of continuous play, my pc crashes and restarts. I get this with other "high performance" games too. This never uses to happen when I first got it, could play all my games in full screen and medium settings. Right now it just seems as If it overheats too quickly.

Does anyone know how to fix this? I've cleaned all the dust inside the pc, checked the fans etc...

Maybe you graphics card or processor is overheating. I had lot of crashing until I installed an Antec Cyclone blower under my graphics card. It sucks hot air and pushes it directly out of case. Now Skyrim is almost rock solid.
