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

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!

glad to hear you fixed it
