So I've been trying to boot my computer over and over again for the last hour. I've tried changing some settings in the BIOS (it does POST) but to no avail. I keep getting this after it POSTs, and then the colors move a little bit but it just stays there (and sometimes then restarts on its own). I have no idea what's going on. This has actually happened before, but usually I can just restart the computer once and it'll work the next time. Any help would be appreciated.
