No luck there. All the files seem to be fine. See the attached screenshot. Anything else I can try, please?

Here's an overnight Memtest screen. I can't see any errors reported but I don't know how to interpret the screen results. Any help?

That snip is basically useless. Corrupt data either from the RAM or from malware.


Can you re-run memtest and download and run malwarebytes?

I have run memtest twice (what I attached was a photo of the screenshot from the second go) and got the same output both times. It looked weird to me but I don't know what it should look like. Can you please give me a steer. What form of final output should I get/make from Memtest, please?

I ran a newer version of MemTest86 (4.20) and it behaved fine. No errors found in over 3 hours. See attached file.

I had done a full scan with F-Secure yesterday, and did one with Norton today. Not problems found.

Any other ideas, please?

PS another BSOD just now while listening to Audible audio book and working in Photoshop CS5. Another memory management. What can I do about this?

The snip shows pass 1. You need to run 6-7 passes to stress the ram enough.

Malwarebytes will find things Norton and F-secure wont. Both F-secure and especially Norton have been known to cause BSOD's on some systems. If it were me I would remove them and replace with Micsrosoft security essentials

If you havent done a system file check please do so

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

Read here for more information SFC /SCANNOW Command - System File Checker

Let us know the results from the report at the end.

solved - I think

Thanks. I gave up trying to track down the fault and re-installed everything. No problems after 16 hours. Thanks for all the help.

Thanks. No BSODs yet but have had a "graphics driver stopped working but recovered" incident. May try a different vga card and driver.
