Entomber :
It's not possible to help you with just this amount of limited information.
- what game are you playing?
- what is your system specs?
- what BSOD error codes are you getting (download something like BlueScreenView to see that)?
- how frequently do these occur?
Apologies, it is really just any game that i play: Garrys Mod, Mount and Blade, Smite, etc.
System specs:
Processor: AMD Turion X2 Dual-Core Mobile RM-74 2.20 GHz
RAM: 4GB
GPU: AMD Turion HD 3200
The bug check code( I think that is what you need) is 0x00000124
The BSOD happens anywhere from 5 minutes of playing to a few hours.
If you need anymore info I am happy to oblige
