Windows 7: BSOD playing guild wars 2 and other games

Could someone please help me fix this issue? it's blue screened so many times it's causing a bit of frustration, because it's a perfectly good computer i don't want to replace it

sorry my crash files are 25.2 MB because there is alot, if suspicious do scan and things, i am pretty sure it is not video card or logitech drivers, only happens in games , never internet browsing , i've left my cpu on before for 2 days, and no bluescreen
