BOOT falilure after RAM installation

HISTORY: Every time when the computer was powered up, there was a message "CMOS battery low" and F1/F2 selection for proceeding. ACCIDENT: I replaced a memory chip (power cord out, static e checked) and started a computer. The computer didn't load (no bios messages, no "beep"0 - black monitor), but the fan was working, CD drive was working. ATTEMPTS: - put back an old memory chip - same story. - replaced existing CMOS battery (tablet 3V CR 2032 lithium battery) with a new one - same story - removed memory chips - same story - reset CMOS jumper - same story HARDWARE: Motherboard type - AMD M810D v 7.5 with nothing on it,except for the graphic card and RAM. Memory type - DDR

    THis is M810D v.7.5 and it holds DDR type of ram.

    I tried it first on my other machine and the chip worked just fine (even it is not exclude what you just said).

    But then even with the old chip it didn't start.

    I had the same problem. I received the low batery message.I didn´t change the memory. One friend asked me to just install a fresh copy and then give it back to him. When he tested it on his house it didn´t turn on. Now only the CD an fan are "working". There is no beep and no image on the screen. Could it be a problem with the CMOS? Have you solved this problem?

    I have the same problem, Only Tried to just flash the cmos and it clear it instead. I found a manual for the board and it said you need the motherboard installation disk. And I cannot find it anywhere

If your battery finally died then most likely your motherboard was cleared. you need to find the motherboard setup disk to set it up for use again. I have the same problem but the cmos clear jumper on the board was moved purposely in my case.I never thought i would erase the board just reset it. OOPS.

Did you make sure that the new RAM was compatible with the motherboard? ...?

Some RAM manufacturers are not compatible with certain motherboard manufacturers....

Dell Inspiron 530. At start up gives CMOS checksum error defaults loaded. Options press F1, F2 or F12 computer does not react. Has new CMOS battery. RAM OK. Did CMOS clear and password reset. What else can...


When a Power Supply is plugged into power, there is a constant 5 Volts present. The 5 Volt Standby Power.

You press the Power On button.
This in turn presses against the Power On switch, located inside it's plastic assembly.

The Power On switch is a Momentary Contact Switch.
Temporary closing it activates the Soft Power On circuit.
A 5 Volt circuit that utilizes the 5 Volt Standby Power.

The Soft Power On circuit 'excites' the Power Supply, and turns it on.
(Sounds like a seedy novel)

The first chipset (Integrated Circuit) to receive power is the BIOS chipset.
The Basic Input/Output System program is initialized.

BIOS looks to see what devices are connected, does a Ram Memory count, turns the Processor on, and hands the computer over to the Operating System.

A checksum is computed as an error-detecting code, to protect the BIOS settings stored in CMOS.
Each time the computer is turned on, this number is re-computed; and checked against stored values.

If they do not match an error message is generated, to tell you the CMOS memory contents may have been corrupted; and therefore some settings may be wrong.
Your BIOS assumed the settings were incorrect, and loaded BIOS default settings; stored in BIOS.

(Default = factory settings)

CMOS Checksum Error Defaults - Loaded

New battery? Nope didn't help.
Clear CMOS, and password reset? Nope didn't help.

Leaves Virus as the problem, or hardware component/s on motherboard; are bad.

My thoughts?
Bad motherboard.

("BAD motherboard. NO,...........you know you have been bad,....don't give me that look. You're a bad motherboard."

Lol!)

That's my diagnosis.


(Unless you put the CMOS battery in upside down.
+ goes UP)

My motherboard will boot but CMOS will not hold the settings


Hi,
This problem is usually caused by a dead or damaged CMOS battery which is a flat, chrome battery about 2 thirds of an inch in diameter and located on the motherboard.
The battery powers the memory which stores your CMOS settings and devices installed such as hard drives.
Replacing this battery should solve your problem.

Best wishes,
Graeme

I do have a ASUS P5GC-MX/1333 REV. 3.05G Motherboard. Whenever I boot my computer it displays "Chasis Intruded" or "CMOS settings"..............and computer won't boot. after this when...


there are two jumpers side by side. one has 3 pins with same distance between them (for cmos)
and
the other one that has also 3 pings but 1 of them a little bit far from the other 2 (Chasis Intruded)

For cmos,
pin 1 pin2 conected is normal operation
pin 2 pin3 conected is for resetting the bios
if reset caried on jumper must be taken back to normal operation positing


Chasis Intruded worning is shown when chasis jumper removed or put on the pin1 so the jumper can not contact the pin2 and pin3.

You must connect pin2 and pin3 by a jumper and restart your computer. That is al.

Bios rom checksum error.. system halted


This error comes when there is low cmos voltage so motherboard flash memory forgot the bios settings.
For that open cpu and then pull cmos cell from mother board buy new cmos cell and replaced it.
Then when you power up the computer press F1 or F2 or "del" key to enter in bios and set time and date and boot option in bios then save settings.
Then it works again if it not works then you need to update firmware for your bios .
Let me know if you need further assistance.
Thanks for using FixYa.

P5RD1-V BOOT PROBLEM


The CMOS, which stands for complementary metal-oxide semiconductor, is the hardware component of a computer that supports the BIOS, or basic input output system. The two terms are often used interchangeably, and the two technologies work together to perform the same basic function. They maintain the low-level settings on a computer, letting the computer know, even before the computer's operating system starts, what kinds of hardware the computer has available, such as hard drives and video display adapters. A special battery located on the computer's motherboard powers the CMOS. To reset the CMOS on a Dell computer, briefly remove and then replace the battery
  1. Turn off the computer. Disconnect all cables and detach all devices, including USB devices, from the computer. Press and hold the computer's power button for 10 seconds after it has been unplugged. This grounds the system board.
  2. Step 2 Remove the computer cover. All Dell systems have a cover panel on the chassis that you can remove so that you can access the system's motherboard and internal components. For some Dell computer lines, such as OptiPlex, the computer cover is held in place by a release latch located on the back of the computer. Pull the latch to release the cover and then slide the over up and away. Other lines, such as Dimension, have large, slotted thumbscrews. Turn the screws counter-clockwise until they disengage from the chassis, the slide the cover off the computer. Dell computers often ship with the computer's user guide in CD form or with the guide pre-loaded on the system's hard drive. You can locate the instructions for removing the cover from your particular system in the user guide.
  3. Step 3 Locate the CMOS battery on the system's motherboard. CMOS batteries range in size from size and thickness from about the size of a nickel to about the size of a quarter. The CMOS battery will generally be labeled CMOS on the motherboard and will be the only battery openly exposed on the motherboard.
  4. Step 4 Remove the CMOS battery by prying it gently up out of its socket. The sockets are specifically designed to allow the battery to be replaced.
  5. Step 5 Wait 30 seconds, and then replace the battery in its socket. This will reset the CMOS. Replace the computer cover to complete the process.

You need to replace the small battery on your motherboard, You can get them at Radio Shack. The battery number is CR2032 it looks about like a quarter. With your computer off, open your computer case find the battery in its holder pop it out and replace it with the new one. Now when you power the system back on go into setup usually by pressing either the "del" key or "F2" key after you go to setup exit the screen by pressing either "esc" or "F10" your system will finish booting and you should be back up and running.

I hope this helps, if so please rate my solution.
