Not sure if this is the correct sub forum, but oh well. ..

We just had a quick power blip that cut power for a few seconds. As soon as power came back on my computer went through the bios display screen fine,but displayed no input detected as soon as it would try and load windows 10

I can access the bios fine, I've have tested two monitors and diffident cables. The computer loads fine as I get the audio feedback when I try and change my dpi or profile on my Roccat mouse.

I've reset the cmos in case it was something weird there, but no result.

Try Startup Repair:  http://www.tenforums.com/tutorials/2294-advanced-startup-options-boot-windows-10-a.html

 

Other options:

here's some repair/recovery/restore options (in this order):

1 - Startup Repair.  Run it 3 times, rebooting in between tries.

2 - System Restore to a point before this started happening.

3 - DISM/SFC repair (DISM doesn't work with W7, although SFC does) - doesn't work if you're not able to boot to Windows (let me know and I'll post a way to do it from Startup Repair)
    

Then please run the following DISM commands to see if there's any problems with the system (from an elevated (Run as administrator) Command Prompt).  Press Enter after each one:
   
Dism /Online /Cleanup-Image /ScanHealth
   
Dism /Online /Cleanup-Image /CheckHealth
   
Dism /Online /Cleanup-Image /RestoreHealth

    FYI - I have repaired systems using the last command even though problems weren't found with the first 2 - so I suggest running them all.

    From this article: http://technet.microsoft.com/en-us/library/hh824869.aspx

    You can also run sfc.exe /scannow from an elevated (Run as administrator) Command Prompt to check for further corruption.


4 - RESET using the "Keep My Files" option (W8 calls this a REFRESH; W7 and earlier doesn't have this function)

5 - Repair install of the OS (Thanks to FreeBooter!):

6 - RESET using the "Remove Everything" option (W8 calls this a RESET; W7 and earlier doesn't have this function)

If using W7 or earlier, this can be accomplished by resetting the system by use of the recovery partition/recovery disks/recovery drive.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

7 - Wipe and reinstall from the Recovery Partition (if so equipped)

8 - Wipe and reinstall from Recovery Media - to include deleting all partitions.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )
