I have just reformatted my computer with Windows XP, everything seemed fine while the computer is running. It won't boot up though unless I enter and exit the bios (I don't do anything in the bios just enter and exit and then it boots up normally). Right now this is more of an inconvenience then anything else, but I'm concerned that this is the beginning of more serious problem.
-My computer is Dell about 6-8 years old
-Windows XP Pro 2002, SP2
-Intel, Pentium 4 CPU 2.40GHz, 512MB
