Windows 8.1 update,black screen, fans on, power and reset buttons unresponsive.

[MutatedPixel]

I am trying to update to windows 8.1. I have tried this before and it has always failed and had to revert to windows 8. This time it got to setting up and then said restarting. Then the screen went black but the fans and lights are still on, the lights on my keyboard and mouse turned off though. After a good 15-20 minutes i tried to press the reset button. Nothing. Then the power button. Nothing. So im wondering if i should force power off or do something else, all help is appreciated.

did the pc fall over to the onboard video?? before you did the updates were they any bios updates for the mb to make it run better under windows 8.1

I didnt check bios updates ill go check now.
How would i check if it went to onboard?
BTW im using an evga gtx 750 ti

I cant check bios because i dont know the version before srry.

if there a gpu and a video port on the mb...move the video cable to the mb see if anything comes on.

it read your mb info and bios rev if you get back into windows. if there video hitting key to go into the bios will on the main screen give you the modle of the mb and it bios rev.

Still nothing on integrated, fans still spinning. Should I hold power to force off?

 

[smorizio]

yes then pull power from the wall and clear the cmos (jumper on the mb).

Ok did that and im starting now

 

[MutatedPixel]

Annnnnnd nothing. Any other ideas?

 

[smorizio]

pull the gpu and one ram stick...see if the system will post wiith onboard video. if it an asus or asrock mb look at the fault led. see if any are on hard. or the de debug has stop at a post code. the last issue can be power supply or mb failure with out another power supply to test or volt meter to read the outputs.

Power supply is very new so probably not it, gpu is new but ill try pulling it anyway, i only have one stick of ram and no spares so i cant do that i did put an optical drive in earlier today so ill pull that.

 

[MutatedPixel]

Nothing, pulled the graphics and optical any other ideas?

 

[MutatedPixel]

Put the gpu back any other things to do?

 

[smorizio]

what your hardware set up now...any fault led on??? I would as a last step pull the mb and with onboard ram and power supply see if it posts outside the case. if after clearing the cmos again nothing happens you down to the mb/cpu or ram failure.

I have a hp pavillion p7 1410 with a evga 750 ti superclocked and a nzxt source 530 other than that its the same as the pavillion. Can you explain why to clear cmos? Im going to bed soon though so im not going to try now. Ill answer tomorrrow if you have any questions.
