No displays at all

[PSUGuru]

Hello everyone, I've come across an annoying issue. 

I have a five year old HP Pavilion which worked perfectly over the years and I decided to get a new PSU and case.

I put the motherboard in the case and the PSU. Now, everything turns on. LEDs on, fans spinning.

However, when I plug in a known-to-work VGA cable, the known-to-work monitor doesn't detect the VGA at all. My computer and monitor doesn't support HDMI.

The motherboard is the MSI MS-7778.

 

I connected it into my TV as well, again, no display.

Tried that. Tried putting them in all the slots, I even put in RAM in from my NAS system (both systems are DDR3, 1600Mhz)

 

I also tested the mobo outside the case. Nothing. I tried DVI. Nothing. And now, fans spin up and maintain. They don't rev up really high then slow down to idle.

 

I've tried a different hard drive. No dice. I amn't going to do anything with the CPU for the simple fact that I don't have thermal paste.

 

I think I might as well replace the mobo, CPU, and RAM. Get a Pentium, or something

doubt it's that serious. it was working before so... does it beep without the RAM? considering your board has an on board speaker.. if it doesnt beep, board is pretty much gone. if it does, board is probably good, either a faulty cpu or a faulty ram

Motherboard doesn't have an on board speaker.

 

The case came with a speaker. When I plug it in to the only place is makes noise, it beeps 100% of the time, whether there's RAM, no RAM, hard drive, no hard drive. All the time.
