BSOD occurring at random times, very frequently

[StellarStar]

Hi all, just joined the forum today to try and solve my BSOD problem, hope you can help me. I read the Posting Instructions so I hope I get this right..

My first bluescreen was sometime between August 8th-20th. It's been happening more and more frequently now. 3 times yesterday. I checked all updates for the hardware but found none that I hadn't already downloaded (everything was older than 2010).
Not sure if this is relevant or not, but while using Skype yesterday my call was dropped and then my laptop immediately bluescreened right after the call ended. It happened once before like that as well, but for the most part it seems very random.


Win 7 Home Premium x64. Original OS was Vista. OEM.
2009 Laptop. 2009 Win 7 upgrade has been installed twice, the reinstall being in Dec 2010.

These were caused by a memory exception. Please run these two tests to verify your memory and find which driver is causing the problem.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.
