When i went to turn on my pc this afternoon after school it was bad news. All the fans and the lights on the motherboard turn on. My motherboard is an asrock extreme 4 970. My GPU is a XFX radeon HD 7870. The problem is that it doesnt display on the monitor. Everything worked the day before, but it wont work today. I've unplugged the GPU and tried booting on with only 1 stick of ram inside. I will be try removing all the components then re-install them tomorrow. Please help it would be much appreciated. Also power button will turn on pc, but wont turn off pc now.

GPU not detected should be 3 or 4 longs beeps.

Should do 1 short beep if it's loading without any issues, in which case it's not the motherboard .

You'll need to check the manual for any other beep codes, I think 3 short beeps is RAM or CPU.

Where can i buy one of those speakers for the motherboard?
 
On most modern motherboards, it should be built in. If the fans are just humming at a constant speed and the cpu and HD aren't loading, than there is a problem with the motherboard,

If the system is booting without any issue but the monitor is black, it's probably something stupid, like the cable is unplugged or the monitor is set to the wrong input.

Would do you mean by not loading? Also when i turn the cpu fan speed control on my case that is a nzxt phantom 410. The Leds get brighter when you turn it up, but the fan speeds don't appear to change.

Hopefully its not my gpu thats $200 :( but at least i got some assistance thank you.
 


The Beeps codes will tell you exactly what the issue is. If you pull the GPU it should beep.

If you have an onboard videocard, you can try using that.

What kind of beeps should i expect if the gpu has failed? Also what beeps to expect if the gpu is still working.
