Please take two of the RAM modules out so that you have only 4 and let me know the results.

OK so you still have the crashing from explorer, etc? If that's the case then I guess put back the memory modules and do the following.
Test RAM With Memtest86+
Please ensure you allow 8 passes of the program!
Download Memtest86+ here:
Memtest86+ - Advanced Memory Diagnostic Tool
Which should I download?
You can either download the pre-compiled .ISO that you would burn to a CD and then boot from the CD, or you can download the auto-installer for the USB key. What this will do is format your USB drive, make it a bootable device, and then install the necessary files. Both do the same job, it's just up to you which you choose, or which you have available (whether it's CD or USB).
Do note that some older generation motherboards do not support USB-based booting, therefore your only option is CD (or Floppy if you really wanted to).
How Memtest works (you don't need to read, it's only for those interested in the specifics):
Memtest uses algorithms (specifically two), namely moving inversion & what is deemed Modulo-X. Essentially, the first algorithm fills the memory with a pattern. Starting at the low address, it checks to see if the pattern was changed (it should not have been), writes the patterns complement, increments the address, and repeats. Starting at the highest address (as opposed to the lowest), it follows the same checklist.
The reason for the second algorithm is due to a few limitations, with the first being that not all adjacent cells are being tested for interaction due to modern chips being 4 to 16 bits wide regarding data storage. With that said, patterns are used to go ahead and ensure that all adjacent cells have at least been written with all possible one and zero combinations.
The second is that caching, buffering and out of order execution will interfere with the moving inversions algorithm. However, the second algorithm used is not affected by this. For starting offsets of 0-20, the algorithm will write every 20th location with a pattern, write all other locations with the patterns complement, repeat the previous one (or more) times, and then check every 20th location for the previously mentioned pattern.
Now that you know how Memtest actually works, it's important to know that the tests it goes through all mean something different. It goes from Test 0 through Test 12, many of which use either one or the other algorithm discussed above, among many other things.
Any other questions, they can most likely be answered by reading this great guide here:

Did you run the test with all four memory modules in or just two?

HDD Diagnostics
What I recommend from here is to run some HDD diagnostics. Please follow the steps here for SeaTools HDD Diagnostics. Run a Long test and a Short test, then report back the results to this thread.

Did you happen to read my last post?
Hi Brian
I tried running the latest SeaTools that I burnt to CD, but it just got stuck at 10% of the short test for what seemed like an length of time that meant something wasnt right. So today I took it out, plugged it into a different machine (via SATA not USB) and tested it with a few utils (SeaTools for Windows, SSDUtility (OCZ monitoring util) and SSLife). I also did another thorough Chkdsk. Everything came back saying that there were no issues and that the drive was expected to run till about 2026 (at the rate I have used it thus far). So I dont think there are any errors with the drive.
I still cant figure out how to get the files that are being reported as missing/corrupt. I haev worked out which KB release they are from, but I cant install it (see above posts). Perhaps you could detail how I can extract the required files from a KB package and then I could manually copy them over. Otherwise, is there a way to force the system to reinstall the KB package, hopefully thereby getting good working copies of the files installed?
Thanks
Robyn

If you want to extract the files from the KB that you downloaded you can do something like the following.
c:
cd c:\MSUFolder
expand -F:* Saved_MSU_File_Name.msu c:\MSUFolder
expand -F:* Saved_MSU_File_Name.cab c:\MSUFolder
c:
cd c:\MSUFolder
expand -F:* Saved_MSU_File_Name.msu c:\MSUFolder
expand -F:* Saved_MSU_File_Name.cab c:\MSUFolder
Hi
Sorry for the gap in communication, I have been away from home in the wilderness without signal.
I probably did not ask my question clearly enough. I am able to opeb the MSU and CAB files (using 7zip) but all that gets me is a bunch of CAT and MUM files. I am not sure how I am meant to get those files extracted to access the DLLs that are contained within the update (or perhaps my understanding of win updates is lacking, and the CAT and MUM files contain code on how to modify an existing DLL?? However, that doesn't seem right to me, and that they would more likely distribute a newer version of the DLL)
My questions from above still stand please:
* I have worked out which KB release they are from, but I cant install it (as if I try remove it it fails, and if I try reinstall it says it is already installed). Is there a way to force the system to reinstall the KB package, hopefully thereby getting good working copies of the files installed?
* Is there any info on what SFCFix is telling me when it mentions issues with the registry (see my post above on the 19th)
Thanks

Not really, no. I've done it a couple times but it's very tricky and risky if you don't know what you are doing.
There is no public documented information. There is an acadamy here where we teach interested users how to be a Windows Update specialists. There's really a lot to it. Not something that can be taught over a few posts.

I do think that is the best course of action. Since you have the issues in Safe Mode, I believe the corruption is too much to fix or a the very least not worth it if you have the option to re-install.
