Hey so as the title suggests my computer keeps freezing whilst playing games such as Arma and battlefield 3 and im trying to figure out why. Here are my specs:

Core i5-3570K 3.4GHz Overclock: 25%
Radeon HD 7950 Sapphire 3GB Boost Edition Overclock: 10%
8 GB DDR3 1600MHz
1TB HDD
Win 7 64
DX11


Here is what i have tried so far to fix this problem:
- Virus scan
- Malware scan
- Registry clean
- Hardware test
- validating game cache on steam
- reset computer to factory settings

If anymore info is needed please ask. Thanks!

Hey well my PSU is a corsair tx 650w and i have tried to remove overclock but the game still crashes. Do you know of anyway to check if hardware is working properly in a more thorough way?
