CMOS Problem

[enfrcr3115]

I am having a problem with a new computer that I have built. All of the components that I used were brand new. This is not the first computer that I have built, but it is the first time having problems.

** When the system begins POST, I get a CMOS CheckSum error loading defaults.
I know that the most common cause of this is a dead CMOS battery, so I replaced it. I am still getting the same error.

** I can get the computer to boot by just accepting the CMOS error, but if I try to make any changes in BIOS, and save the changes the computer will not POST after the restart, I just get a black screen. The motherboard seems to be working ok, and all of the fans are running. The only way I get it to POST again, is to clear the CMOS settings.

** Once I get to the OS, and I want to shut down or restart, It won't POST again, unless I clear the CMOS. (re-occurring problem).

I have contacted the motherboard tech-support, but have had no reply.

---Intel Pentium Dual Core E2180 2 GHz CPU

Thanks in advance to anyone that can help

Looks like an RMA is in order ... your CMOS/BIOS chip looks to be the culprit.


Try pushing it down, with quite a reasonable force, into the motherboard.

When you removed the battery did you leave it out for a few minutes?
