Default Blue Screen Problem

I have a problem with my laptop PC. I need advice on this problem.

Computer: Acer Aspire 5920
OS: Windows Vista Home Premium Service Pack 2

At the time I encountered this problem I was running Windows Update. The message, in full, that has come up on my computer's blue screen is as follows:

"A problem has been detected and Windows has been shut down to prevent damage to your computer.

DRIVER_IRQL_NOT_LESS_OR_EQUAL

If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Technical information:

***STOP: 0x000000D1 (0x00650043, 0x00000002, 0x00000000, 0x 83641129)

*** iastor.sys - Address 83641129 base at 83601000, Datestamp 46ff320c"

This is the first time this blue screen has appeared. I have not installed any new hardware or new software.

It looks like a problem with the Intel chipset driver, download and (re)install them for your Acer here: http://support.acer-euro.com/drivers...k/as_5920.html

Thank you for your response and your advice. Can you please tell me what it is I actually need to download. When I've downloaded it how do I go about installing it?

If you have x86 (32-bit) Vista, from the first dropdown select the Chipset driver Intel, if it downloads as an exe file, it should self-install once double-clicked.

Click the down arrow aside of Driver and Utilities and select Chipset Driver Intel.
If you are running a 64 bit version of Vista, instead of the above, click the down arrow aside of 64 Bit Driver and select the same file.

Or go here
Code:
ftp://ftp.work.acer-euro.com/notebook/aspire_5920/vista/Drivers/
and select Chipset Driver Intel. It might have both in the zipped file; I don't know.

I just downloaded and unzipped. There is an x64 folder though it does not contain an exe file. Look at the Readme and Help text files. Then click setup.exe to run in one of three modes, as explained in Readme.

I have downloaded and attempted to install. However, the install process stalled and said that I had a newer version and asked if I wanted to continue. As I didn't think it appropriate to install an older version I chose to not continue with the install.

iaStor drivers are often unsuited to normal Atapi, PCI, IDE, SATA controllers. Intel RST (Rapid Storage Technology) drivers (iaStor is one) are pretty specific to later Intel chipsets, they will cause issues if incorrectly installed. Please revert to the older drivers you downloaded, at least for testing purposes.

May I be clear about this. Are you recommending that I should install the older driver. When you say "for testing", do you mean just to see if the problem happens again or to do some specific test?

Yes, install the older driver. If you don't get the same BSOD in about 10 days or so, you found the culprit.

If you do get another BSOD, please zip and attach the dump and I'll try to see if there are further clues there.

Thanks!

I've downloaded and installed the older driver from the recommended web site. I shall now keep a watch on whether I get the blue screen again.
