Hello everyone,
Occasionally my BIOS would not be accesible and i have fixed this several times with a CMOS reset.
Now, even after CMOS reset, system gets stuck on a white dash tickling with the mouse of the BIOS present and usable.
I have tried:
  • Battery off for 8 hours
  • CMOS reset with jumper
  • CMOS reset with metal object
  • Removed all peripherals (Only one memory, removed all HDD, USB3.0, video card, Wifi)

Interesting thing is the system won't power on (literally dead) with the reset CMOS jumper in short.
I AM pressing the correct keys to enter BIOS. Its DEL for Setup, F12 for Boot options (inaccesible) and END for Q-Flash (inaccesible as well).

Current status: System goes directly into that tickling white dash. Can't boot any OS or do anything.

Thanks in advance for taking the time!

My system:
  • Gigabyte GA-Z97-HD3 Rev. 2.1
  • EVGA GTX 980 SC
  • Hyperx 16gb
  • i7 4790s
  • Gigabyte 600W PSU
