PC won't POST/boot??

[plasma23]

I have an asus Rampage iii extreme mobo..and in the last few weeks, it was working but it randomy crashed with a blank screen and sometimes didnt boot or even post.

Well few days ago it failed to pos completely with no beep, just blank screen. So i got the motherbaord by itself, with only 1 stick of RAM and CPU, and GPU and tried to boot and still nothing.

Using the BIOS swith on the mobo, on one the red light gets stuck at DRAM (however im sure nothing is wrong with the RAM and i inserted stick properly). The other BIOS setting, the red light passes the CPU and DRAM but gets stuck on the VGA.

I used another working GPU and same result.

what could be wrong?


asus rampage iii exreme
i7 950
corsair h50
corsair dominator GT, 6gb
ati 5850
corsair tx650
coolermaster 690ii

boot it without out any RAM you should get a beep error if not then the Motherboard is not getting to that point of the POST, then only two things can be at fault Motherboard and or PSU.

More likely DIMM if the light is on.....

I had the same problem with my M4A88T-V EVO/USB3. Turns out the DIMM slots had gone and I had to RMA. I strongly believe the problem is the same with yours.
