Was on my pc last night and was about to get off for the night when i accidentally put my pc on sleep. I turned it back on to shut it off, and the computer would freeze at the BIOS screen. I am using two sticks of g. Skill ripjaw 4gb. I started pulling sticks of RAM out and restarting, and after pulling one stick out I was able to get past the BIOS screen. However, I was able to get past the BIOS screen with either stick, just not both at the same time. Now, all of a sudden my keyboard turns on but pressing any key appears to do nothing. Any ideas as to what the issue could be?
