I have a Toshiba Satellite Laptop running Windows Vista, and I have been experiencing alot of random bluescreen errors and restarts lately.

I ran an AVG virus scan and it came back with a "broken digital signature error" citing an Intel Chipset Software Installation Utility.

I further ran WhoCrashed and came up with this report:

Conclusion
________________________________________

14 crash dumps have been found and analyzed. Note that it's not always possible to state with certainty whether a reported driver is really responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.


Can you tell me where the error truly lies and how I may fix it?

Please, explain this:

I ran an AVG virus scan and it came back with a "broken digital signature error" citing an Intel Chipset Software Installation Utility.

AVG refused to run with the above error, or....

[bingdaddy]

AVG completed the scan normally and the log showed one detection, which is the broken digital signature.

I have attached a PDF file that has the list of "WhoCrashed?" errors and on the last page (scroll way down) is a screenshot of the AVG log identifying the broken digital signature.

Could this faulty signature be causing the bluescreen dumps?

Could this faulty signature be causing the bluescreen dumps?

Possible. At first, seeing your errors, I was thinking, RAM issue, but it'd be a good idea to reinstall chipset driver and see, if AVG will report same thing, or not.
Go to Toshiba site, download and install chipset driver (Intel Chipset Software Installation Utility).

[bingdaddy]

I downloaded the Chipset software and installed, and still am having the same issue.

I ran the AVG scan and WhatCrashed analysis, and they came up with the same error.

I few days ago I ran a Toshiba system diagnostics that came with the laptop and the RAM checked out ok. Do you trust this or is there another test you would like me to try?

[Broni]

What kind of RAM test did you run?
If you have more than one RAM stick installed, I'd try to start and run the laptop for a while on one RAM stick at a time and see, if same errors happen.
I'm not sure about that Toshiba test...

A. If you have more than one RAM module installed, try starting computer with one RAM stick at a time.

NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option A

B. If you have only one RAM stick installed...
...run memtest...

1. Download - Pre-Compiled Bootable ISO (.zip)
2. Unzip downloaded memtest86+-....iso.zip file.
3. Inside, you'll find memtest86+-....iso file.
4. Download, and install ImgBurn: http://www.imgburn.com/
5. Insert blank CD into your CD drive.
6. Open ImgBurn, and click on Write image file to disc
7. Click on Browse for a file... icon:



8. Locate memtest86+-....iso file, and click Open button.
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:



10. Once the CD is created, boot from it, and memtest will automatically start to run.

The running program will look something like this depending on the size and number of ram modules installed:




It's recommended to run 5-6 passes. Each pass contains very same 8 tests.

This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.



The following image is the test results area:



The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.

I do have two sticks of RAM. I pulled one early yesterday and have run it for 24 hours without error. I have swapped them and I am now running to see if this stick fails. (I have a feeling that it will)

The two sticks that I have are 1gb each. Would it be ok just to pickup a 2gb stick and replace the bad 1gb? (I don't have the budget right now for two new 2gb sticks) Or, do they both need to be replaced at the same time?

[Broni]

Let's see, what will happen with 2nd stick.
2GB of RAM is perfectly enough for Vista.
...and, as you can see, from troubleshooting point of view, it's always better to have 2x1GB sticks, than just one 2GB stick.

[bingdaddy]

Actually, I was thinking about just picking up one 2GB stick and adding it to the one good 1GB stick for a total of 3GB. Will that work?

I have not had a chance to run this 2nd stick through the paces, just yet. I'll get you an update soon.

[Broni]

I was thinking about just picking up one 2GB stick and adding it to the one good 1GB stick for a total of 3GB. Will that work?

Sure thing. As long, as you have 2 sticks, that's good for troubleshooting.

[bingdaddy]

I have run the system with just one stick of RAM at a time with no errors. Then I tried running each stick, separately in different slots, with no errors.

So, I put both sticks back in and the machine ran just fine for 48 hours! I thought it was back to normal, but this morning it has failed on me three times already!

Any other thoughts or ideas?
