I can get into the boot option menu via F12 I believe, but if I select CDROM, nothing happens and it goes straight to loading operating system.
I have never done a full BIOS reset since this is the first time I have run into any problems with a build.
I should have a USB drive around here so if I find it I will give it a try.
Sorry,your right, F12 which was meant
Full bios reset.......these next word are taken from the mystro himself, "Dark Mantis" (Moderator) with due credits....
follow these instructions exactly.
Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.
Once done remove the motherboard battery for at least one hour before replacing it.
Next plug back into the mains supply and boot.
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.
Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.
Back again!.......report back if you have a win........if not you may have a crook .........something.
