Biostar MCP6P M2+
I'm trying to work out a new budget build with a Biostar MCP6P M2+ but it's running into problems. The first board wouldn't post no matter what I did so I RMA'ed it and got a new one. This one wouldn't post either at first but resetting the CMOS jumper solved that. Unfortunately after it posts it gives this error:
""CMOS checksum error - Defaults loaded
Press F8 to enable system configuration
Press F9 to select booting device after post
press F1 to continue, DEL to enter setup"
If I press DEL to enter setup and try to change any BIOS settings they won't save, the computer just restarts and then doesn't post. The fans and hard drive spin but there's a blank screen and no beep. I have to reset the jumper again and then it posts but gives the same error. If I press F1 to continue it tries to boot, but since I'm not gonna try to install an OS on a system with bad BIOS it sees that there's nothing to boot from and just waits for me to put in a bootable CD. Then if I restart the system after that it goes to the black screen with no post and no beep and I have to clear the CMOS again.
I successfully updated the BIOS but it didn't change anything, everything's still the same. Also changing the RAM, power supply, CPU (using either AM2 and AM3 because I thought that maybe the AM3 cpu was the culprit but it wasn't) and taking it out of the case and running it on a piece of cardboard didn't help anything.
Any ideas? I hope I don't have to RMA again because Biostar makes me pay for shipping
