R51 IRQL_NOT_LESS_OR_EQUAL shutting down message

[acc]

I have an R51 that after 3 minutes of starting will shut down to a blue screen with the message "IRQL_NOT_LESS_OR_EQUAL" and tells to check that all hardware is correctly installed. The error report says:

BCCode : 1000000a BCP1 : 00000029 BCP2 : 00000002 BCP3 : 00000000
BCP4 : 804DA6DB OSVer : 5_1_2600 SP : 2_0 Product : 256_1
C:\DOCUME~1\ALEJAN~2\LOCALS~1\Temp\WERfd5c.dir00\Mini102507-03.dmp
C:\DOCUME~1\ALEJAN~2\LOCALS~1\Temp\WERfd5c.dir00\sysdata.xml

It did this sporadically, but now I have a hard time making it work, I have to reboot it 5 - 10 times before it works.

The only new thing I added was a Netgear external wirelss antenna that I need to connect to the wireless network with new encription. The card is working fine, but problems started after that.

I tried removing the Netgear card and the problem persists. Any idea of what to do?

Thanks a lot,

I am not sure what causes this. Maybe someone here does. When this error appeared on an in warranty ThinkPad that I had IBM replaced the motherboard. When I have seen this more recently on an out of warranty ThinkPad I just restart and it works ok.

So I am inconvienienced occasionally. Your problem appears to be more persistant.

What is the model and type of your R51?

I'm pretty sure that's a driver issue. When you said you removed the card, do you mean that you physically removed it, or did you also uninstall it? If not, try that... Or try checking for newer drivers.

I've gotten around this a couple of times by re-installing OS....however, I don't claim I know what the actual problem is.

I've had an R51 once upon a time, with a 1.5 PM processor that kept on giving me this message and bluescreened when I was trying to load the OS. I've sold it as a parts unit on eBay and have gotten a positive feedback for it, but to the best of my knowledge and belief (in the interest of full disclosure: I am NOT a computer tech), that has been a motherboard issue.

Good luck.

Dear all:

Thanks a lot for the advice! I am not very well verse in computers, but I'll give it a try to your suggestions and let you know the outcome. I do not know the model of my R51, it's at home.

Thanks a lot,

Hi acc. I just had a very similar issue with a T23. The problem turned out to be a bad stick of RAM. Try booting your laptop with one stick at a time and see if the issue resolves.

hi goofyGAguy,

Thanks for your email, how can I test the RAM, any suggestion of how / where I can learn how to test individually ram sticks?

Thanks again, sorry for the lack of computer knowledge,

Alejandro

Memtest did not catch the problem for me but removing the bad stick made the computer rock solid again.

Hi all:

Thanks a lot for all the advice. I tried several of the suggestions. I could not figure out how to run memtest, I download the program and apparently run, but I could not get it to do the test, so I gave up on that. A friend suggested that the location of the file indicated spyware, so I run Spyboot and catch and solved two problems (althought I did not find an obvious connection with this problem). The last time I had troubles with the machine, a week ago, I decided to let it run all the time (problems are mostly at starup) and since that I had no problem (it restarted today fine as well). So I don't know whether was the spyware or something else, but it seems fixed now.

I would like to thank you all for your input and hope that this may be usefull for somebody else as well.

Cheers,

Alejandro
