Computer Freezez+Cmos Checksum Error

My computer is freezing after loading up. Not always the same time but shortly after it loads it freezes. I have run Norten Utilites and Scandisk everything comes back normal, nothing seems to be wrong. Still it freezes. It has been going on for about three weeks not every time, now though it just freezes all the time. Have been using MSCONFIG and selective startup. Loaded the System file and freezes once loaded. Uncheck that loaded win file, then static VxD's and startup group. Seems to work fine but after awhile it will freeze but a lot better then the past three days. Should mention it did not freeze with just win and static VxD's or maybe just not long enough. With startup group or eviorment variables it will freeze eventually.  I notice on some of the reboots I get the CMOS checksum error- load defaults. I enter bios setup and everything except time seems to be working at there correct value. Even loaded optimal settings and default settings and finishing loading and it would freeze. Untill I load windows without the sytem file then I had no chance of keeping my computer running. I made it thru this post and my computer is still running. Any help is appreciated. I feel I.m preety knowledgeable but can not figure it out. Before I start going thru the System File one check at a time till I figure it out. anyone have a quick answer.

Running
AMD Athlon  1336 MHZ
Award Modular Bios v6.00PGN
256 Megs  Memory, 32 shared with video
SIS is my video, controler and sound cards
Computer is a Lan Plus 1.5 years old.

One other thing noice in my system info a problem device

 DEVICE: ACPI IRQ Holder for PCI IRQ Steering               PNP Device ID: ACPI\*PNP0C0F\00000001
ERROR CODE: 22


Anybody reconize this and what it is???
           Thanks in Advance Pat

Whenever the "CMOS checksum error" happens the FIRST thing to do is to REPLACE the CMOS battery.  Even though the system is only 1.5 years old, that is old enough for the battery to be low.

Replace the battery, reset the BIOS settings, and see if the problem is solved.

Plus run a memory tester on the system once you have replaced the battery.  See

for a free one.  Search down the page.

If the battery is ok, could be a faulty bios chip,or corrupted CMOS memory.

As a last resort, you could try flashing the BIOS.

oops, just noticed the ACPI error.
Shared IRQs!

Make sure you have the latest motherboard chipset drivers, move PCI cards around to try and stop irq sharing on the Graphics card, in plugNplay settings, set PNP OS to "NO".

At the last option, reinstall windows with ACPI disabled.
(method depends on OS).

Alright Guys,
  Change cmos battery, made sure all wires and cables are tight, ran memory test everything past. Still freezing up once booted up and loads normal. As long as I run in diagnostic mode, not processing sys.inf file. I have a shot of my computer running for more then a minute. I have check cmos everything is as suppose to be, don't think that is corrupt. How do you determine bad BIOS chip other then last option. How do you Flash the Bios, never had to do that. I have tried every trick I know but nothing seems to work and everything seems to be as it should. Can not find anything software or hardware that is not as it should be but obvious something is not. Anymore suggestions appreciated. Also I have a utility that updates the BIOS. Think I should run it giving the state of the computer.

Nope.  Can you guarantee it won't crash while you are updating your BIOS?  You can't.  And if it goes down while you are trying your system is dead.



If the memory tester ran OK, and I presume you ran it for an extended period of time, like a couple of hours, then the problem probably seems to be your software.   Consider a reinstallation as suggested by wyliecoyoteuk.

DON'T FLASH YOUR BIOS!!!  That is NOT the problem here!

You have a HARDWARE problem, most likely BAD RAM but it could be other components also.  First try swapping your RAM and see if that clears things up.

As for the software I have windows and original software on a recovery disk and have reinstaled three times already. Second time I was having a problem with the mouse would not respond the way it should and would not let me change it. Did the recover everything works. Also notice before the thrid recovery that my entire system.inf file got wipe out except boot sequence, but that is back to. Here is another thing once I shut my computer totaly off it will not boot upeven thru BIOS. I put Norton Rescue Disk or Windows Startup Disk it will boot and then I can restart it no problem. I was thinking memory to but I have no problem, usually once in a while I do, when I run in selective startup; do not load sys.inf file or in safe mode. Everything works fine only when fully loaded problems. As for software after three recoveries I would think that it is not software. I used the recover disk a year ago no problem. Will try the memory but my thinking something is wrong on the motherboard. Any more suggestions appreciated or anyone reconizes what is wrong.

In regards to the memory test I ran 30 loops which was about 3hours 32minutes. Every loop passed the burn in test. So I am a little skepitical that the memory is the problem. I would hope it would have showed up then, but will try memory swaping. Even if not that I was looking to add memory any way. Thanks for all the suggestion guys so far.

Thanks guys for all the help. After switching out memory, cpu, ant network card came to the realization had to be the motherboard. Went out got another one put it in and I am back up and running. The answer was the motherboard. Thanks for the help guys.
