Asus Z97 deluxe error code 4f

[rlcal]

So when I boot my computer from cold 75% of the time it will hang on error code 4f (DXE IPL is started) I don't know what that means is half the problem.  From looking around on the internet I think it's one of these 3 problems:

CPU is dying 

Ram is dying 

Motherboard is dying 

BIOS is corrupt (as it boots sometimes I don't think it's this)

 

If anyone has any idea what one it's most likely to be or if it's anything else please let me know.  I might try flashing the BIOS tomorrow unless someone advises against it. 

 

Thanks

Did you try resetting the CMOS?

Do you have to pull the battery for that or can you just unplug the PSU? 

[jj9987]

Unplugging the PSU will not reset it, pulling battery is too much work.

 

This motherboard has a CMOS reset button at the bottom, just on the left of the debug LED. It's written in the motherboard manual to be sure.

Sorry I'm just reading this now, so my computer needed cleaned anyway so I pulled the battery while I cleaned it so it was out for about 20 minutes and it hasn't made a difference.  So it must be something else.  Have you any other ideas?

Narrowed it down further, so unless both my sticks of ram are bad it's not them as I tried them individually in each slot with the same result.  Would a clean install of my OS likely help at all do you think?

 

edit:

Or should I try flashing the BIOS first

Bought a new bios chip and that seemed to fix it.
