I built my PC a little over a year ago, and the only problem I've ever had is being unable to get into the BIOS. If I hit the delete key during post (or try any of the other options other than letting Windows boot) I just get a black screen. I heard that resetting the cmos battery could solve this problem, so I took it out for about a minute and put it back in. Now, it seems like my motherboard doesn't know to boot from the SSD I have windows on, so I just get a black screen if I try to enter the BIOS or load windows. Can anyone help me with this problem?
