Cannot Reach POST after changing GPU, not even with old one, possible memory issue
I have recently built a new computer, and everything has been working fine, but just today I installed my new graphics card (Gigabyte Radeon R9 280X OC 3GB). The PC worked fine just prior to me installing the new card.
But now, when I go to boot with new card installed, I get 3 long beeps. I researched the code and it appears to signify "Without memory" even though I didn't even touch the RAM, and I was wearing an anti-static wrist-strap connected to the case through the entire process.
I tried the old GPU in again and it produces the same result, with or without RAM or GPU in.
I tried all 4 dimm slots but none of them make any difference. All of the fans still spin and the LEDs still come on.
So tell me, do I need to buy more RAM, or is there another issue?
specs for reference -- -AMD 8320 8 core CPU -old gpu Radeon 7770 -8gb corsair vengeance RAM - 1 stick -750W power supply -AsRock 990FX Extreme3 motherboard
All parts new except RAM which is about 6 months old

Try completely clearing your CMOS motherboard settings, which will be pulling the wall power, and using the motherboard clear jumper option, your M/B manual has the clearing instructions, and then trying again.
try pulling out your RAM and then put it back into the slot. Remove all your RAM and insert only ONE stick and boot. If it still beeps, try ANOTHER (only one) RAM stick. Make sure CPU fan properly "Hindged". Also try what 4Ryan6 instructed
