hi
i did some throughout testing to my pc which stopped working few days ago. it gives no picture at all in screen at startup and OS wont load. fans and stuff spin.
to find the problem i removed all devices then i changed CPU , Mobo, PSU , GPU and monitor. but since none of those helped i thought it was the Mobo that was broken but when i put old mobo with its own stuff (mem, CPU and third PSU) it didnt work either! same problem. which i dont understand why both of my computers malfunction the same way. so only thing i could think at this point was that the computer case is somehow bad and causing this problem.. could it be? i think this is very strange , seems like both my mobos are broke.

CPU: Athlon II X4 630/AM3 2.80GHz 2MB-L2 95W
PSU: ANTEC PSU 650W 12CM ATX12V2.2 80+
RAM: 1GB 1333MHZ DDR3 NON-ECC CL9 DIMM
Mobo: MSI 770-C45 (AM3 AMD DDR3 SATA GLAN ATX)
GPU: sapphire HD 4850 512mb

Reassemble the PCs outside of the case. The case could be shorting the system. Hit up the Basic Troubleshooting Guide for more info.
 
thx Danny. what kind of platform should i assemble it? could i run it on the padding that came with the motherboard box?
im just not sure if its safe on top of painted wood table...

Assemble it on either that wood table or the motherboard box. Definitely not the padding.
 
Did you swap out graphics cards? I noticed your mobo doesn't have onboard video.
Edit: you didn't list the exact model of the MSI mobo, some have video onboard and some don't
