URGENT HELP PC will not post.

[Steven Villarreal]

This started happening just a week ago but now it won't even post.

I have tried unpluging everything and seeing if that helps but to no avail nothing. I tried booting with just one ram stick in every ram card slot but that doesn't help either. Also I tried putting my graphics card in another PCIE slot and still nothing. My monitor which is on when I turn my pc on does detect when my pc powers on but is blank. My mouse and keyboard are also not turning on when I turn my pc on. What do you think it is? I get no beeps either and no weird lights, literally everything seems fine.

My Specs are..

AMD FX-6300
ASUS M5A99FX PRO R2.0
EVGA GTX 970 ACX 2.0
Corsair Vengeance DDR3 1866 2x4gb
Corsair CX 500

i'd guess power supply. those cx series power supplies are notorious for stuff like this.

maybe try a new one like this:

you could also test it with a psu tester:

keep in mind though, a psu tester isnt always accruate and the psu may still be the problem even if it tests fine.
