Various and Constant BSOD's.

After three weeks of meticulous testing and replacing parts all to no avail with diagnosing the cause of the BSOD's the culprit of the problems has been determined to be the CPU.

I've recently found out that when I run memtest from a clean startup no errors are shown on the CPU, however after leaving the PC on until it BSOD's and then performing a memtest I get thousands of errors on the CPU. Also if I turn the machine off for 30 minutes and then run a memtest again no errors are shown.

I get a new CPU on Wednesday, and if as assumed that is the cause I'll report back with an update.

Fitted the new PSU and guess what it BSOD'ed at just over 4 hours once again.

Just out of curiosity I decided to run memtest86 again and this time it started failing after about one hour, this is somewhat annoying as the memory was previously tested and passed. I bought a new pair and all passed in each slot even after leaving it on overnight with all four sticks installed and completing 10 passes.

So my memory has become damaged since installed, or they were already near failure when previously tested and managed to pass.

Problem finally solved, it was memory after all.

I initially had 4 sticks, one of the pairs failed from day 1 which was then replaced. Both pairs then passed memtest86 for 10 runs. After that I continued to get BSOD's, then after changing all components with new components and still not finding the cause of the problems, I retested the memory again and one stick of each pair now failed. Which is rather infuriating, just goes to show that just because a test passes the first time it doesn't mean it actually passed. As you can't prove that a pass is actually a pass, but one failure is enough to determine a fail.
