Random BSOD while surfing, gaming or idling

No worries - I'll keep an eye out for your reply :)

Yes, it appears to be faulty RAM or a faulty motherboard RAM slot.

Proceed to test each RAM stick individually for 8 passes in motherboard slot #1 and report back.

Those errors mean that one or more RAM DiMM's require replacing.

Re-run 8 passes on each DiMM individually (it will be reasonably quick). Any DiMM that generates those errors must be replaced - they cannot be fixed.

So the 4th DiMM passes 8 MemTest86+ passes?

You need to replace those DiMM's with new ones - all of them must be the same as the last working DiMM, before we can troubleshoot further.

hi Golden, bad news. i have 3 of 4 DiMM pieces which gave errors.

of the last one which i did 8passes twice, i'm still encountering BSoD. attached dumps again. ((

Now follow the "Part 3: If You Have Errors:" of How to Test and Diagnose RAM Issues with Memtest86+

Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:

No code has to be inserted here.

It is a RAM, a bad RAM.

But if you have got a result like that:

No code has to be inserted here.

It is a motherboard issue. The particular slot is bad.

So do the test and let us know the result accordingly. It will consume a lot of time, but worth doing it.

No need to upload anymore crash dump before the memory issue is fixed.
