I have a problem. On my secondary PC, I first had a GTS 450 which was running perfectly fine and still is with that PC, but then I bought a used GPU on a local store, it is a Sapphire Radeon HD 6870. I could not use it until recently, when i got a psu to use it, I had an Antec ea-380w, Now I have a Seasonic S12II 520. When I first started up the PC with the 6870, it showed red dots(even on BIOS)but the even weirder thing is that it did not on Windows. When I tried to install the drivers, the screen has gone black: each time I restart it, it goes black at a random time and i can't get the screen back Unless i reboot it

Pc specs:
Q6600 G0 2.4 GHZ
ASUS OEM cooler coming from HP Desktop
6gb DDR2(2x1 gb Samsung)+(2x2 gb memory express)
ASUS p5b-plus
Sapphire Radeon HD 6870
1tb Seagate barracuda 3.5"(2013 edition)
Windows 10 Home 64 bit
Seasonic S12II 520
Antec nsk 4482
Worst cable management ever, that case is not good.
Samsung syncmaster 2233sw 22" monitor

I want to Play GTA V and some csgo on that PC. I need a fix.

Sorry for bad english.
 
Solution
Looks like your used card you got is bad. You can try doing a BIOS update on your system, try the card in another system with a good power supply.

Is There any way to fix it?
