Windows 7: Randomly occurring BSOD, becoming more frequent

Randomly occurring BSOD, becoming more frequent

This computer's first BSOD was a few months ago, but they have been getting more frequent, along with random freezes.

They usually come in succession, so I will get 2 to 3 BSODs in an hour and then none for a few days.

Thanks.
  • Windows 7 Profession 64 bit, full retail version
  • Windows Vista was originally installed on this computer, and it is partitioned into this operating system and Windows 7 Home Premium 64 bit, both of which have BSODs.
  • The computer is about 3 years old, and I installed the operating system about a year ago.

Hello Rupert Connors & welcome,
Nothing definitive was gleaned from your analysis.

Please run these two tests to verify your memory and find which driver may be causing the problem.

If you are overclocking anything reset to default before running these tests.
In other words STOP!!!



1-Memtest.
Quote:
*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*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.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+



2-Driver verifier

Quote:
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.

Thanks, I will try this soon.

Just another clue I forgot to mention, the computer occasionally randomly instantly restarts; I am using Windows normally, and then suddenly it flashes the Dell boot screen and continues to boot to Windows.
