PC wont boot

[saur0]

Ok so weird situation, I have a PC that was working fine, but then it wouldn't boot. Nothing had changed I used the PC then went to bed and the next morning when I pressed the power button the the motherboard LEDs just glowed red and it did not boot. So I went through the RMA process with the mobo and got a replacement, but the PC still won't boot. When I power it up the mobo lights up and everything looks normal, but the RAM doesn't light up and the PC won't boot. I've attached a speaker and I don't get any beep codes, and i've tried everything I can think of, removing all but one RAM, no GPU 

 

unfortunately I only have one rig so I can't test the CPU in anything, the PSU seems ok as the motherboard powers up but nothing else does. Any suggestions?

 

Motherboard - Asus ROG Maximus XI Formula

CPU - 9900k

PSU - Dark Power Pro 1000W

RAM - G.Skill Trident Z RGB

Could be a power surge,Did you have a lightning storm or something like that?

Nope, and I have have a large UPS on it. But yeah all I can think of is it was some kind of static or power issue. I'm now wondering if the CPU is toast and that's why it won't start. But i don't have anything to test it with.

I have given up, looks like i'm now building a second rig to fault find my main rig!

If it isn't the mobo the next suspect is the PSU so get that first and try it out. 

 

 

Also have you tried without the UPS? 

Those things can make issues as well,  you know that right?
