ASUS Maximus Extreme Viii will not boot - Code 55 but RAM OK - Sudden problem
Hello - help needed.
I have the ASUS Maximus Extreme Viii motherboard which has work seamlessly for many years. I have made no changes to it aside from ensuring the bios is up to date. Yesterday I came downstairs to find it was switched off. Assumed a power cut or something had happened. However, it will now not boot. I cannot even get to bios. There is power and the LED codes flip and change but seem to rest on 55 which from what I gather means no memory detected. I took the memory out and it is working fine in my works computer. I’m running a full test on it now so clearly that’s not the problem. So what is? I suppose there’s only the chip left to test?
I followed all of the other advice on this forum of reseating RAM and even reseated the CPU - but since the PC has always been stationary, unchanged, and formerly working I don’t think it’s to do with incompatibilities, seating issues, new hardware etc.
Any ideas - it’s a great machine - loathed to change CPU and motherboard without really understanding if it’s a necessary thing to do.
PS sometimes the codes do rest on other numbers like 40
Cheers, Jim*

Really appreciate the quick response - I’ll try that. I also note that if I press the MEM OK button the final resting Q Code is 32 which I think points to the CPU being the problem. Tried reseating it again but no joy. Jim
