Today I upgraded my RAM on my Asus P8Z68-V PRO motherboard from 4GB(Corsair XMS3 2x2GB) to 8GB(Corsair Vengeance 2x4GB). The PC was working perfectly today until I changed the RAM. The PC started up with all fans running, but black screen/no signal. I tried putting the RAM in and out several times to see if that was the problem, but nothing changed. I noticed the red light next to the RAM were light. I then tried switching back to the old RAM, that worked just an hour before, but no... The exact same problem. After reading around the web, I found out clicking on the memOK! button would help. I pushed it down for three second(as advised) until the light stopped, then restart, the red light started flashing, then restart again after some time, but same problem. Everything runs in the case, but no signal on screen(the screen/cables is not the problem...).

Can anyone help?
 
Is the memory installed correctly? All the way into the slots?
Maybe try setting the BIOS to default settings? Or if the memory is compatible, see that its set to default voltage/speed/timing?
 
The screen is black, I can't access the BIOS. I have tried several times to adjust the RAM-modules to fit, I can't for sure say it's completely fit. The RAM is on the "guaranteed" list in being compatible with my motherboard...
 
It's very hard to check, cause there is very little space for me to work on. The CPU and GPU is pretty close to the memory modules, so I can't see from any sides, just from above.
 
Not being seated could be the prob then. Esp since the original doesn't seem to be working either. The GPU should be easy enought to remove, and cpu fan if there's one oof those in the way. Somehow just need to first make sure they are seated correctly and being in the correct channels probly matters.
