MSI HD 7850 Twin Frozr III random game crashes need help.

[Bobybobp]

Hello, i have had my PC for about 9 months now and i have has this problem for quite a long time and i am getting fed up of it now. When playing a game i get these random crashes on my pc where the screen goes to a 'no signal screen', but the pc will continue running as if nothing has happened. This crash could happen 30 seconds into running a game or it could happen 2 hours into a game.

i have no idea what is going on and im not even sure if its the graphics card but that seemed the most likely case to me. Here is my specs if it helps:

It is hard to know...
can be a lot of things.

do you have any overclock? if you have.. just reset to default..
do you have any program to monitor your GPU and CPU temperatures?
do a fresh windows instalation...

is you still have problems... you can try with another graphics card (or onboard) OR ou can start removing any hardware from your computer that is not essential for it to work, like extra HDD, cd/dvd drives, extra fans,.
