**Note: Right as I was posting this I noticed the typo in the thread title...apologies.

Hello all, I just discovered this helpful-looking site while Googling around for help ending my laptop's habit of crashing with BSODs. I am running Windows Vista Home Premium with SP1, on a Toshiba Satellite A305 laptop if that makes any difference.

So far I can't find any definite link between my actions and the causes of the crashes. They occur when I'm doing fairly unremarkable things on my computer like browsing the internet and listening to music, things that ordinarily don't cause any problems. As soon as I reboot, I can repeat whatever I was doing exactly without causing a crash. I can't think of anything major I did shortly before the crashes started, besides installing Skype and Ventrilo, which I uninstalled to see if it would help. (It didn't) I don't have any system restore points from before the crashes started (though I recently changed system restore to make backups every 5 days instead of 1 so I can go back farther).

Anyway, using a tutorial on this site I finally figured out how to crack open my crash logs. Oddly, the dumps from my latest several crashes seem to be missing; I think I may have rebooted too early after the crash for them to be saved or something, and will correct this in the future. The following is the debugger's translation of the log from the first recorded crash. (If more logs would be helpful I can post them; there are a total of 7 saved)

* Bugcheck Analysis *

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arg1: 000009850000007e, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80001e79463, address which referenced memory

I can't figure out much from this dump; the tutorial said that posting the log here was the next step. One thing I did notice from analyzing a few dumps is that the process name is different, so this isn't being caused by one bad application (I think). Any insights into the possible nature/cause of my BSOD problem are greatly appreciated.

Hi -

The bugcheck = 0xa = a driver accessed paged memory at a time it should not have (IRQL too high)

Update your Intel wifi driver - http://downloadcenter.intel.com/SearchResu...llation+Utility

Interesting. For the update utility, how do I check which chipset I have?

I followed this tutorial to try and figure out which chipset I have. It says to look for something like a 'memory controller hub', but I don't see that and am not sure which one it could be. I'm posting a screenshot of my list of system devices in case someone here has a better idea.

From what I can figure out from the Driver that is referenced in the Bugcheck Analysis you are running a 64Bit version of Windows Vista.

Your Wireless Drivers can be found here.

According to Toshiba that laptop series came with an Intel 3945ABG Wireless adapter installed in it. The link I gave you will put you right on the page for download. Download the first file referenced as it is executable and will automatically update your wireless drivers.

To answer your question as to which Chipset you have installed in your laptop, according to both Toshiba and your Device Manager you have a Mobile Intel® GM965 Express Chipset.

Hope this helps,

Thanks--I guess I'll know if it worked if the crashes stop.
