Today I bought a new hard drive for one of my computers and installed it. After the installation, as I was starting up the computer, I recieved the following error messages: "Floppy disk(s) fail 80" and "CMOS checksum error - Defaults loaded" After recieving this message I restarted the computer but all that happened was the computer powered on and emitted a long beep until it shut itself off. Nothing appeared on my screen. After trying a restart again, and getting the same results, I opened up my computer, set the CMOS jumper to clear, and cleared it. I then powered the computer back on only to recieve the same error messages as before and then after restarts, the same long beep and shutdown. Does anyone know what could possibly be happening with my computer?

--UPDATE--
I replaced the CMOS battery with a new one from Radio Shack, and still no luck. I tried again to enter in the correct values in the BIOS setup. After saving theses settings and restarting the computer, it again emitted one long beep and turned itself off. I had to reset the CMOS with the jumper again before it would power on correctly. Once the computer powered up I again saw the same two errors as listed above. Do you think I am going to have to replace my MoBo? If so do you have any idea where i should look for a model number?

Thanks Again,
Trey

Did you boot into the Bios and check to make sure the drive is recognized?
Is this a sata drive or IDE?
Or you sre you set the OS disc as primary and the jumpers on the new disc as secondary?
I'ld definetly check the bios settings and see whats goin on there.

I checked the BIOS and everything is setup up correctly as it should be. My hard drive is IDE and the OS drive's jumper is set to master and the secondary drive's jumper is set to slave. So far no luck :(

Thanks,

From the way the problem first appeared, and the symptoms, my first thought is a weak CMOS battery.

The errors that appear on POST are consistent with the CMOS settings being wrong for the hardware connected to the motherboard.

Check and or replace the CMOS backup battery.

Enter BIOS setup and adjust the settings as needed for your system.

At a minimum, you need to make sure that all of the drive settings and CPU speed settings are correct.

I thought I had correctly confgiured my CMOS and BIOS, but I'm begining to doubt it. My BIOS version is a "Phoenix Award Bios v6.00pg" Have any pointers on the correct setup? Let me know if anymoe details are needed.

Thanks,

Did you try uninstalling the new drive to see if the original config still works?

by treyb_2009

I restored all of my hardware to the original settings, and still no luck.

Thanks,

1)Check the main board connectors
2)Check the memory modules by taking out and replacing
3)If the CMOS battery does not fix the problem,it may not be good

The long continous beep indicates that CMOS has a problem,to which you are looking at a main board problem that does not look good at all
