CMOS setting distrubed for mercury PVM7 ver 1 board

Probably a memory problem.

That usually indicates a bad CMOS battery. The CMOS battery can be replaced.

Hi there,

When starting your PC, the following error message is displayed:

CMOS wrong
CMOS MEMORY size WRONG
CMOS Checksum Bad
CMOS checksum error defaults loaded
Warning! CPU has been changed please re-enter cpu settings in the cmos setup and remember to save before quit!
You are prompted to:

Press F1 to resume
Press F2 to load default values and continue


This is due to the fact that the CMOS, which contain data related to the BIOS, has been reinitialized and that your PC has been reset to factory settings.

Solutions:

Reinitializing the BIOS

• • Before making any costly maintenance try to reinitialized the BIOS.
• Change BIOS battery
  • If the problem persist this may be due to the fact that the battery powering the CMOS (when the computer is shut down allows the CMOS to store information), is depleted.
  • The CMOS battery is a small pin found on the mother board, you can refer to the manual provided with your motherboard to change it or have the nearby computer technician change it for you if you don't want to risk any damage.
  • More information with: Replacing the battery of your motherboard (CMOS battery)

Post back if it is not working we will be happy to help you.
Hope this helps.
Cheers!!!!

This normally means the CMOS backup battery on the motherboard needs to be replaced. Most boards use a commonly-available 3-volt coin cell. It just pops into a holder on the board. Change the battery and that message should quit bugging you.

[CHANGE YOUR CMOS BATTER WHICH IS INSIDE YOUR CPU CASE]
I do not think you fixed the CMOS battery - (backup battery = CMOS battery)
According to the error codes, you have a dead backup battery and the time is not set. Makes sense?
161
(Dead battery.) 1. Go to Checking the Backup Battery
2. Backup battery.
3. System board.
163
(Time and date were not set.) 1. Set time and date.
2. System board.


Go to www.ibm.com Find and download the user manual, and the "hardware maintenance manual."
Do you know how to get into bios/setup?

Start with the machine OFF. HOLD DOWN and CONTINUE TO HOLD THE "F1" key.
WHILE STILL HOLDING "F1", turn the power on, and CONTINUE TO HOLD "F1"
This will get you into the bios "setup." You should check the date, bootup order, etc, and reset.
I would check the "wire" you think you reconnected---you may just not have actually reconnected it.
The "hardware maintenance manual" shows you how to maintain this machine, and it explains the meaning of the error codes.

This will get you started on looking for the manual:

You need to press F1 and go into the BIOS to setup and detect everything. You will need to set the date, verify it detects your hard drive and memory, and enable/disable items as you need for your system.

Once it looks good, do a Save and Exit.

I would replace the battery as the 1st thing, however I would also change your cpu fan for a new one and reseat the processor. Also get some decent cpu paste and make sure this is applied properly, and dont forget to wipe the old stuff off!

Does your case have anywhere were you can place some fans? It sound slike you have two problems to me, the battery being one and the overheating the second

Whether it shows your cmos checksum error press F1 to continue or f2 to load default.? If this is the problem than kindly switch off the system check for the cmos battery and change the cmos battery and set the date and time properly in the bios and save it by pressing F10.This will resolve your problem.and if not than check the jumper setting on the motherboard is it set to clear cmos and if so kindly remove and set it properly to adjacent jumper ok. Have a nice time.

Load fail safe defaults from CMOS/ deseabled the CMOS.
OR press F5 when booting & continue.

It will probably be your cmos battery that is flat and losing the saved settings, this can be located on the motherboard, it is a flat disc shape (CR2032)
