Can i sell my broken gaming pc?

I have a desktop that always gets a blue screen of death when i try to play games, I don't know what is wrong with it and have tried multiple things to try and get it working, and the company i bought it from really could care less about my issue (cyberpowerpc) so i'm thinking if i can just sell it for parts and buy a new rig i will. How much do you think i could get for it? Specs below.

Cyberpower lan part mid tower case

Gigabyte Am3 Mobo

HIS Radeon HD 6850 Graphics card

500w PSU (not sure of brand)

Seagte 500gb 5400rpm Hard Drive

4 gb of DDR3 corsair ram

Amd Phenom ii 1055t black edition quad core cpu (3.4GHz)

Thanks.

reinstall windows

Thats an okay gaming PC. Should play most things on medium. Don't sell it, just reinstall Windows and you should be fine. If your HDD is going bad like mine was with bad sectors, just get a new one of those. Not worth replacing the whole PC when you don't see much benefit.

Do a fresh Windows install and update all your drivers.

Did you just buy this gaming PC? When did it start acting up?

1. Chkdsk

2. Check your ram

3. if all fails, reinstall windows
