Psu+mobo+cpu/hsf.
Does it power up?
If not your down to 3 parts.
I was playing league of legends and my PC froze with grey vertical lines on both monitors. I shutdown the PC by pressing the button. Immediately after when I turned it on, the hardware would boot up fans and lights, however no display was seen on either monitor. Figuring it might be my graphics card, I unplugged the DVI connectors and plugged them into the Mobo itself, however still nothing. I then unplugged the PC and reset the CMOS by taking the battery out and placing it back in. After that I plugged the PC back in and now it seems to not turn on at all, PSU doesn't seem to work at all, not even the orange light from LAN cable. I'm guessing this problem was the PSU the entire time? The PSU is the EVGA NEX750B
