Trying to boot my PC and it will not. It displays the CPU in the bios, then freezes. Nothing happens. Post Code 50 displays. I think it should be displaying the memory next, but it does not. I unplugged ALL USB devices. Tried that. Took everything apart and put it back. PSU is fine. I had it all running, but then I shut it down (WINDOWS 7 x64), it installed 40 updates, I tried to put in additional HDD, and then it wouldn't boot. It was an IDE drive that I did not have properly set to "cable select" mode like I Should have. 

Anyway, I moved all the RAM around and then I found C1 errors as well when it was is certain spots. It will not do anything when it freezes at "50." It will reset with a button press, but when I get a C1 error - it can only take a manual turn off.

I reset CMOS, did the battery thing as well. I have no idea what else to do. I'm all out of options. I took out all USB headers, etc. I only have MOBO, RAM, and CPU. Everything else is unplugged (it has integrated graphics). I just want to at least get into bios to flash it to the new bios.


With all the memory in, I get F1, C1, and C3.


Now I'm getting 0C, with two memory modules in.

Sorry, I didn't see this earlier.

50- Initialize USB controller.  the next would be 52- test all memory above 1MB

C1 - Memory Presence - Base memory detect
C3 - Turn on extended memory, cache initialization
0C - Reserved - no description
F1 - not listed in manual

These are from the manual. You used to be able to download it(not sure if you still can) it has a lot more info than the one that came with the motherboard.

Right. Now since they won't replace it for me, what can I do?
