Ok so..
I was playing World of Warcraft.
I pressed the home button to display the bottom bar on the monitor, to switch between WoW and another window I had opened.

When I went to click on this window, the screen went black, said No Signal, and the blue light turned yellow.
My mouse and keyboard went offline, and stopped responding, even after unplugging/plugging them back in.

The PC itself never turned off. All of the fans were still on and functioning properly.

I tried restarting the P/C the hard way (unplugging power cord, because holding down the power button did nothing to turn the p/c off).

This also, did not work. Same results.
No Signal, Keyboard/Mouse still offline and not working.

Wireless USB was getting power, but was not making connection to the Router, just a solid blue light unwavering.



Does anybody have any clue as to what the fuck is going on here??

I have taken the Graphic Card out of the new rig, put it in the old rig, and it powered up just fine.
Monitor came on, everything working like normal on the old PC with the New PCS graphic card.


So my last two guesses are...Power Supply slowly going bad, or Motherboard connectors for video card have gone bad.


Any other opinions?
Would be greatly appreciated.

What motherboard do you have?


/e In other words...if your motherboard has a 2nd PCI_E x16 slot...try the vid card in that slot.

/ee Another thing that can happen when you shut down a PC "the hard way" is that it can confuse the BIOS.

Might try turning the computer off, turning the power supply OFF, then pulling the CMOS battery for about 30 seconds. Then put it back in, turn the power supply on, turn the comp on.

It's an Asus M5A78L-MLPLUX MOBO

See my two edits, above.

The power supply doesn't have a separate power-button. That I can see.

It's literally just a plug.

My older 400W PS does have a power button.

Basically what i've done so far is....
Take the graphic card out of the New Rig (Issues) and put it in my older rig, booted up just fine, no issues. So I know it's not the card.
I just took the SSD out of the New Rig (Issues) and put it in my older rig, booted up just fine, no issues.


I'm a little hesitant on doing the Power Supply next. I'm not exactly computer-building savvy if I can not remember where a certain plus / wire goes.




As far as having another Graphic Card slot, the MOBO does not unforunately.

I've been reading up on the issues I'm having, and it ranges from the CPU being bad, to the MOBO being bad, to the PS going bad, to the Graphic Card going bad.

I know it's not the PSU or Graphic Card.

Also, I tried plugging one of my older Graphic Cards into the New Rig (Issues) to see if maybe that would work, nope.

Could the connectors on the MOBO have gone bad if it's not picking up either graphic card?

I would try pulling the CMOS battery first. That will reset the BIOS to defaults.

As for the power supply switch, they are usually on the back of the power supply. The switch will labeled 1 and 0.


What is the make and model of the power supply and of the vid card?

Vid Card = Nvidia GTX 650ti
PS = Insignia 520W PS - Model - NS- PCW52050


What you're talking about removing on the MOBO, is the big circle silver button, that looks similar to a watch battery?
