BIOS 317 04/26/13
Core i5 4570
Be quite L8 400W
MSI GTX 760 (latest driver) at the time removed
Issue
At the time no grafic is shown and no access to BIOS is possible!
With no grafic card installed and security jumper removed bios entry screen shown but F2 has no effect.
Afterwards the clearing requst is shown (can be responded by key board) - system request shutdown and reinstallation jumper.
After power down the second boot up no bios entry window is shown; 4 lower beeps - with blank screen are to be heard.
Battery was already removed for 10 h no effect and power unpluged this did not show any effect.
What can be done to bring the system operational again?
