hi
while playing a game system got hanged and the display was gone
restarted the system but display came up with 2 white lines and as soon as the windows reached the log in it crashed BSOD.
i tried to restart but same thing happened tried to start in safe mode but the display screen was full of white lines.
tried resetting bios and reinstalling gpu also on different slots but nothing

now whenever i start the system there is no display the mobo is showing
Asrock Dr Debug Error b2
cpu fan and gpu fan is running even the gpu fan is blowing hot air but no display.
is the gpu fried?
can i do something to make it work again?

system- cpu-4770k, ram-kingston- 16gb, smps-750tx corsair, gpu-4870 amd

thanks

I have the same problem, I was told that the problem might be the BIOS. Because the computer runs fine when I use the onboard graphics. I have a XFX Radeon HD 7970. I'll try a different card and will see if that fixes the problem. So far 1/10 tries the computer boots up fine with the graphics card, but during the other times, I get error b2 on the graphics card. I'll keep you updated.

@bein and @Fedorp1

I'm also hung on ASRock Dr. Debug code b2 (same problem as the OP, but on a fully new build that has not yet posted), and I'm curious regarding your solutions - an update please?

I took my computer to computer specialised shop for them to do some troubleshooting. when i got it back they said that my cpu and gpu are broken maybe because too high voltages on cpu and gpu or somesort of power spike.
