Nearly always when I first power up my PC the boot fails. It displays the motherboard logo , even sometimes passes by the windows 8 logo , then a blank screen & I have to reset my computer , which solves the problem.
Why does the first time boot always fail ?
Probably because Fast Startup fails. Info is written to the Hiberfile to speed up the boot process, and in some cases the info is corrupt. When you reset the Fast Startup is not employed and you are able to boot.
Try Windows Diagnostics to fix the problem...
First try System File Checker
Windows key plus 'X'
Choose Command Prompt (Admin)
Type
sfc /scannow then
Enter
It finds and fixes errors in Windows, but doesn't always report them. Run it and see if the fault disappears after re-booting your system
If corrupt files are found that can’t be fixed, try
Dism /Online /Cleanup-Image /RestoreHealth (Observe spaces before
/)
Re-run SFC
To view CBS Log
findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt
Search C drive for sfcdetails.txt or navigate to C:\Windows\System32 and scroll down.
If the problem persists turn off Fast Startup from CMD Prompt as above, type
powercfg -h off then
Enter
