lol what have you done
done
maybe you had problems during installation like you said
Disable sleep/hibernate mode through control panel or try entering these one at a time in command prompt.
c:\windows\system32\powercfg.exe -change -monitor-timeout-ac 0
c:\windows\system32\powercfg.exe -change -monitor-timeout-dc 0
c:\windows\system32\powercfg.exe -change -disk-timeout-ac 0
c:\windows\system32\powercfg.exe -change -disk-timeout-dc 0
c:\windows\system32\powercfg.exe -change -standby-timeout-ac 0
c:\windows\system32\powercfg.exe -change -standby-timeout-dc 0
c:\windows\system32\powercfg.exe -change -hibernate-timeout-ac 0
c:\windows\system32\powercfg.exe -change -hibernate-timeout-dc 0
Having these modes on a desktop are pointless.
