I bought a XFX ATI Radeon HD 6770 1024MB GDDR5 PCI-Express Graphics Card for my PC, and after a few hours play all was going fine, then I noticed that my PC would not work, instead I would recveive 1 beep then 8 short beeps, so I'm guessing my grapgics card was not getting any power or something like that, I opened the case and noticed that the cable leading to my rear fan (that connected the PSU to the graphics card) was burnt, so I took it out and then my would work yay
Or so I thought, after an hours play I heard some kind of hissing/sizzling from inside my PC; turned it off for an hours or so and then tried to turn it on again, but then it would not work.
So I bought a new PSU, a Cooler Master RS550-ACAAE3-UK GX-Series 550W Power Supply Unit, and a new fan.
After an hour or so of working, my monitor screen froze, and then after a few seconds I would get a BSOD, with an error about the "Attempting to reset display drivers timed out" or something like that, the display drivers, BIOS and motherboard were all up to date, yet I would still get the BSOD.
So, I took out 6770 and put in my old 5450 and no BSOD, at all.
On saturday I returned the 6770 via post to the company I bought it from, and today I got an email from them saying they could not find a problem with the graphics card.
So I'm wondering, is there something wrong with the motherboard or what?
I uninstalled the 5450, inserted the 6770, installed the drivers from the AMD website, unistalled when the graphics card wouldn't work, re-inserted the 6770 back in again, and installed the drivers again; but it still wouldn't work.
I have a:
ASRock P55/USB3 motherboard
Corsair 2gb DDR3 PC3-10700H 667MHz memory
And the PSU and graphics card from above
