PC quit posting,please help me fix it.

Ok i had picked up a used gaming pc from a pawn shop for $50 ,that would post but not boot into windows,I got past that with some help from here.

 

I have been leaving it running for a couple day installing games to test on it,other than that I did run Heaven Benchmark to get some temps(cpu never went over 68c),and I did also a little bit of an overclock on the GPU.

 

Well this morning i got up and the fans were spinning but no video,I have tried clearing the cmos,I tried different things with the 2 sticks of ram.

 

I even tried changing out the video card for a known working card,and still nothing.

 

 

Now i am guessing it is either the PSU.CPU or Mobo.

 

What does it sound like to you guys? What should I check first?

PSU is the easiest to try, and depending on the CPU socket, it's wavering between testing the Mobo or the CPU first, if it's AM2, AM2+, AM3, AM3+, LGA 775, LGA 1156, or LGA 1155, then it's easier to buy a cheap 10$ cpu off of ebay then to try and replace the motherboard.

Ok the CPU socket is AM3+,i do have a phenom II 925 i could try, i do also have an AM3+ board with one the 2 pcie x16 slots bad,and i have an antec earthwatts 500w psu in another system.

 

So i should be able to test all,i am just not sure which to do first.

Power supply first, then CPU, then the motherboard.

OK so far both power supply and CPU replaced and still nothing going to try motherboard now.
