Recently my computer started displaying just a black screen randomly and the gpu fans would go to 100% this would sometimes happen as soon as the PC started after the beep or just after half an hour or sometimes not at all, however soon it started doing it as soon as it was turned on and/or the beep would be 1 long and 2 short beeps so I thought my GPU was broken and so I borrowed a radeon hd 6770 from my friend (my GPU is a radeon hd 6870) and his GPU works perfectly on my pc so I was certain my GPU was broken until he borrowed mine just to be sure and it worked perfectly on his pc and I have no idea what is wrong or what to do since the 6870 does this problem as soon as the pc is turned on but the 6770 works like a charm for hours on end. my computer is about 1 year and 3 months old which I built myself if that means anything
My pc:
gigabyte ga-970a-ds3 motherboard
msi radeon hd 6870 OC edition
amd phenom ii x4 965 black edition
3 x corsair vengence 4GB (1600)
Corsair cx600w psu
1 x pci wlan card
1 x cd/dvd rw drive
1 x 2tb seagate hard drive (7200 rpm I think)
4 x 120mm fans
Any help would be greatly appreciated.
Thanks in advance.
