Cooler works, but computer won't start/boot

[guilleves]

Hello. Yesterday I tried to turn on my PC, and found out that only the coolers are working. System won't boot, no signal on the display whatsoever. I was able to turn it off only by unplugging the electric source. Components are pretty clean too.

My mobo is a MSI 7302, and the CPU is an AMD Athlon x2.

What could possibly be the issue? Was working fine until yesterday.

Thanks in advance.

Make sure ALL cables are connected properly (including monitor cable). Also confirm video card and DIMM's seated properly.

If issue persists, try using only ONE DIMM and in different slots. And/or try other known working DIMM's (and in different slots). And/or try the original DIMM's in another computer.

If still have issue, remove video card and try it in another computer. And/or try another known working video card (borrow one if necessary).

If issue continues, try another known working PSU (borrow one if necessary).

If issue still persists, then suspect faulty motherboard.
