Hi topps and welcome to TechSpot :)

all you should have to do is clear CMOS. this will reset your BIOS back to it's default settings.

most motherboards have a CLR CMOS jumper. if your does, then turn your computer off and move the jumper into the CLR position for a few seconds, then move it back into the NRM (normal) position. then turn your PC back on.

if your mobo doesn't have a jumper, than you will have to remove the CMOS battery for a few seconds. both methods will clear the CMOS and reset your BIOS.

cheers :wave:

could you please explain what these componetns are such as..

CMOS battery
jumper into the CLR position
CLR CMOS jumper

its not that im dumb, but im only 15 and i am going in to computers and computer programming + engineering so this would help :) :: by the way ill have a look at my mobo manual to try and find it::

ahh its all gravy now, after looking at my mobo manual i found the cmos battery removed it replaced it and then got it running normal again thanks! :D

glad to hear you fixed it :)
