Brain Ache - BSOD problems, 2 gfx cards one new + totaly new rig

Will you tell everybody if your problem only occurs when playing the original game mentioned - pleeze.

There are cases where duff wiring in the case can cause problems.
Was the case new - which model/serial?

Ok i just completed 2:30 running memtest. It completeled two cycles in which it passed both with no errors. I am unable to leave it running over night as the computer is in the bedroom and GF dosent want it on haha.

Supose this rules out memory errors then?

It is very highly advisable to run Memory Tests for no less than 6 Hours.
You can not get an accurate testing by running a couple of passes.
Even some seasoned techs don't realize this. They should.

With 8G of ram, you should be running Memory Tests for at minimum 6 to 8 hours.
If you (and you should) run the extended tests. There are long tests that run in the background that will show other errors only in a long term testing run. These will be intermittent errors that may be missed by short tests.

The only time you can really get away with a 1 or 2 pass run, is when you get errors.
If you get errors right away, then you definately have bad ram, and you can start testing individual stick in individual slots to test both sticks and slots on the motherboard. You will find the bad stick or slot within a pass or 2.

You should also test with all memory installed first. Let that go for as long as needed to do a full thorough test. At minimum 6 hours. If one pass takes 1 hour, then this is 6 passes, you really want to get in about 7 to 10+ passes.

There is a caveat, Some testers, if you let a Memory Test run too long, it can give false errors.
Memtest86+ can do this, not always, but sometimes. How do you determine a false error?
Run the tests again with a different tester, then test again with the other.
If one is giving errors and the other isn't, then either, you have bad ram, or are getting false errors.
I know this sounds confusing, but it's really not. On really tricky RAM or Slot problems, there is a bit of art and guessing involved.
But usually it is a straight forward "Am I getting errors on either test?" Yes? "More than likely I have bad memory or a bad slot."
False errors do occur more often than they should. But they are not a rampant issue.

I have come to rely more on Windows Memory Diags, but it is not a bad idea to run full extended tests using both.

Once you have thoroughly tested with 2 testers and for long periods of time, can you actually say, your RAM is good.

Which is why it is always safest to pick only RAM that is listed on the motherboard manufacturer's compatibility list.

Windows Memory Diagnostic

Which is also a part of Windows and can be run following this Tutorial

Also,, as stated in my earlier post. This is a quote from the first link in this post from Microsoft...

If you want to test your RAM more completely, you can run the extended test suite by pressing T while Windows Memory Diagnostic is running. You should then let Windows Memory Diagnostic run overnight. If you change the test suite or any of Windows Memory Diagnostic settings, the test pass will restart from the beginning.

And yes, compatibility is always something to consider when building a new system.
