Startup problem, stuck at EFI screen

Hello,

So I recently put a new computer together that has been doing well the last month or so, until now. When I booted it up this morning everything seemed to be going fine, it went past the initial screen, then past the motherboard screen but after that I get stuck on something talking about my EFI shell version 2.3 or something along those lines.

The top of screen says "EFI Shell version 2.31 [4.651] - Current running mode 1.1.2" followed below by "Device mapping table" which includes what seems to be a bunch of hard disks that it calls fs0, fs1, fs2... and blk0, blk1, blk2...

Finally, the last line says "Press ESC in 1 seconds to skip startup.nsh, or any other key to continue". Nothing happens when I try pressing ESC or any other key though, and I can give commands by typing where "Shell>" is (it's below the "last" line). For example, if I type exit and press enter, I will enter BIOS.

I don't know how to get past this screen and I can't remember doing anything in particular lately that could have caused this problem. Please help.


Thanks,

Joe
