BSOD and freezing during gameplay 0x7b

[Robodude]

I've recently installed a Galaxy GTS 450.When I play games they crash,freeze,and usually have a BSOD.I don't know if it is a bad GPU,hardware issue,or software issue.Any help would be appreciated.

Sounds like a video card driver issue. I suggest doing the following...

1. Download Driver Sweeper free version to your desktop screen and install.

2. Download the latest diver(s) for your video card but don't install them.

3. Uninstall your video card drivers and reboot your PC into Safe Mode. Run Driver Sweeper and remove ONLY the video card drivers. I had someone use it on their chipset drivers! If it doesn't find any video card drivers that is quite okay; just leave all other drivers alone.

4. Reboot and install new video card drivers.

It didn't help.I tried beta and older drivers.
