Hello,

I have recently upgraded my home PC with new motherboard, CPU and RAM. Since then i have a weird bug that i cant seem to get my head around to fix.

Basically whenever i am in the metro UI start screen, at random times when i left or right click it will hang my system with NO BSOD. My monitors go  to sleep my PC is still on and the fans are still on as well as the LEDS andmy keyboard and mouse but they are frozen.

I cant remote onto it from my logmein account to see what is going on.

I have tried the following:

• change power options to disable sleep timeout
• re installed fresh windows 8 then update to 8.1
• changed my main HDD and re installed windows 8 then updated to 8.1
• installed and updated all of my hardware (mouse, keyboard, motherboard chipset)

It is very random and frustrating as i am an IT engineer and i cannot figure out what is going on. I have estimated that my system at peak load pulls around 590W of power and i have a 750W Modular Gaming PSU.

I also have a NVIDIA GTX 295 Pre watercooled.

I really cannot think what this could be and would really appreciate some guidance/assistance with this. In my opinion I do not think it is to do with my PSU or GPU as it is ONLY doing this in WINDOWS 8.1 METRO Screen and nowhere elese not even the metro screen in windows 8 before I update to 8.1

Many thanks in advance for this.

Go to Nvidia control panel>Adjust Desktop size and position>2. APPLY THE FOLLOWING>Scaling>NO SCALING

You should consider using a bigger PSU this made a difference in my sli Rig

many thanks for the quick reply and i will try this but do you mind me asking wouldnt a graphics issue be PC wide not just metro

You would think, but we are dealing with a finicky metro

Edit: I don't think it is the problem but ruling out things do help

Aye, did you plug and unplug a usb device to see if it wakes up.

If that fails then goto Device manager, USB controllers, Properties>Power Management>uncheck ALLOW THE COMPUTER TO TURN OFF THIS DEVICE TO SAVE POWER. Do this for all usb hubs. If you could use a hot key to view the power at the time this happens in usb power, it will show what is going on at the time of blackout ruling out power.

again thanks for the reply - im not sure what you mean by hot key to view the power? also the scaling thing didnt work and turning off Cool n Quiet didnt work either

however when it did it this time i had music playing and the music was still playing when the monitors went off.

Hi,

Please check Event Viewer, it should have the error message recording when this problem occurs.

In addition, In my opinion, this should be a driver problem, please check and upgrade all your hardware driver to be latest for test.

i have looked at the system event logs and these are the messages im getting:

• The previous system shutdown at 19:55:07 on 23/01/2014 was unexpected.

• The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

• The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
  {C2F03A33-21F5-47FA-B4BB-156362A2F239}
   and APPID
  {316CDED5-E4AE-4B15-9113-7055D84DCC97}

This security permission can be modified using the Component Services administrative tool.

• Crash dump initialization failed!

I have also updated the drivers for my graphics card, mouse and keyboard they are the only pieces of hardware connected. I have told windows to boot to the desktop as to avoid this happening.

Any further assistance would be greatly appreciated
