|I was playing Witcher 3 yesterday and suddenly the screen turned black. Then, it restarted and stuck in EFI Shell. |
My PC's spec
CPU: Intel i7 4770
Motherboard: MSI H87-G43
RAM: Kingston (forgot the model)
GPU: Sapphire Vapor-x 7970
PSU: Antec HCG-620M
with one SSD, one HDD and one optical drive
I guess why I stuck in EFI Shell because all the SSD, HDD and optical drive cannot be detected. I can go into bios and use the the BOARD EXPLORER to view the hardware. I found all six SATA ports show empty but others can be shown in the EXPLORER. What happens to the drives? I have tried
1. clear CMOS
2. unplug the SATA cables and plug into different ports
but no luck. And I have tried to plug the SSD into another PC and can boot into my windows 7 so I think the SSD has no problem.
Also, I want to ask a question about the optical drive. Do the optical drive need to be detected to eject the tray? I have plugged power cable into the optical drive and it has no response totally. Is problem about the PSU? However, the motherboard, GPU, CPU fan and chassis fan can turn on.
Can someone tell me how to fix?
