I keep getting random BSODs. I have not been able to get the debugger to work in order to narrow down the error. So, I've tried to follow the instructions on the info required (files are attached) and any help gratefully received.
thanks!

System Spec:-
- Win 7 home Premium x64 ?
- it is a home built PC with an OEM version of windows
- Build from new this July
There are 9 suspected causes. It is one of three things.
The OS:
Run system file check
Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then
SFC /SCANNOW
It may need to be run up to three times before sucessful
Read here for more information SFC /SCANNOW Command - System File Checker
Let us know the results from the report at the end.
RAM or a driver. Please run these
1-Memtest.
RAM - Test with Memtest86+*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.
2-Driver verifier
Driver Verifier - Enable and DisableI'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.
First off, thanks for the very detailed response. I've been travelling, so have only been able to run SCANNOW and MEMTEST so far.
SCANNOW - no errors found (screen copy attached)
MEMTEST - ran for 8 passes and no errors found (photo of screen attached).
I am now going to run the driver stress tests and will update later.
I've now run the driver verifier. First I couldn't even get into Windows as vsdatant.sys caused crashes. It didn't save any data to Minidump, but I took a photo of the screen, which is attached. I then used "safe mode" to get into windows and disabled driver verifier for now...
thanks!
