BSOD at startup

I have been trying to get it to work with Memtest 5.x (not 100% certain of the version number) burnt to CD but it defaults to the older version included on the CD though it has certainly worked in the past with the newer version but not with any consistency. That was when I tested the initial memory for RMA with Corsair but a screen shot from that should give memory timings and the like anyway. I don't have any photos of that on the phone by the looks of things so what I will do is have a dig about on the NAS drive at home as all the photos on my phone are backed up automatically to that so should be something there.

I will also download the latest USB boot version of memtest and see what that does and update accordingly.

Thanks

Sorry for the delay in getting back to you - been busy with work and other stuff over the last few days. Finally managed to get around to testing with a USB bootable version of 5.01 of memtest 86 - only did a quick run but the memory timings are what they should be as far as I can tell. Photo attached.

Thanks

Back again for another go at resolving this problem. Latest files attached.

A bit of background on this - just ran the tests for the standard 8 passes regardless (I set it going before going to work and let it get on with it). Also had a BIOS failure before running the tests for Stick 2 Slot 4 - I moved the memory and the PC beeped like mad so assumed that this was the memory not seated properly so shut it back down again and reseated it (I checked it prior to this and looked to be seated correctly but that is no guarantee). Restarted and the PC would not boot at all or would spin the fans up but not boot into BIOS and then would shut down again. Eventually got it to boot again and and a screen shot came up stating that the BIOS (B14.0418.1 is the latest version and I had done a BIOS update previously so assume this was the same version) was corrupted and then the board restored from the older version held in backup (B13.0910.1). As a result I have now lost all rpm ratings for the PWM fans installed - they all now read at 0rpm! The plus side (trying desperately to find that silver lining) is that I got a full 8 passes out of the memory without an error for the first time but strictly speaking it was not from a cold boot which may go some way to explaining this. I then re ran the tests for Stick 2 in Slot 3 again and we are back to the same errors again.

Looking at the results I think I have got two different issues here - all the tests for Stick 2 throw a huge amount of errors up until test 4 on pass 1 and then it runs perfectly - no errors at all. Those for Stick 1 will throw random errors across the board. I have had my suspicions about the board being an issue for a while (the RAM has already been RMA'ed once as previously noted) and while I am not stating that the memory is not at fault again I think that the next action would be to RMA the board back to Gigabyte for replacement and then run the tests again to see if we get the same results or just errors on Stick 1 (which is what suspect will happen).

As an aside - Essenbe you mentioned that you had seen the same issue before without managing to resolve this. Did that include a replacement of the motherboard?

Thanks

No problems doing that Essenbe - just force of habit compressing them. Sorry for any inconvenience.

Time to update the thread...

RMA'ed the motherboard and it was sent back with no fault found which I was somewhat sceptical of in all honesty and then had to move house so the issue was put on the back burner for a while.

I finally got round to looking at the issue a couple of days ago and given my scepticism I ordered a different motherboard (Asus H87M-E) to test with as a friend was looking to build a PC on similar lines and so I could sell him the board at a discount if it proved not to be the issue. Dropped the board in last night with just the processor, RAM and CPU heatsink attached and it all looked fairly good and a single pass test in Memtest went OK so I was feeling pretty confident last night that I may have resolved the issue. Decided to do some cable tidying and test it again tonight and it started out all right but has now gone back to the same issues that I was seeing before - errors being thrown up to Test 4 on the initial pass and then nothing (see attached). The only thing that had changed was cable tidying and plugging in the two fans that cool the hard drives which runs off a molex connector through a 3 pin fan speed controller which I have removed again but I am still seeing the issue.

Should add here that there are no drives connected - it is effectively a bare board booting Memtest off a USB key for the purposes of testing to see that everything was OK.

The only three things that remain as common from the outset now are the case, the processor and the PSU. I feel that I can rule the case out as a potential issue here so it points to one of the other two being the issue. My current suspicions lie with the PSU as I can unplug the power and wait for the status LED on the board to fade and then plug it back in and get the issue to repeat itself but this is unlike any PSU issue that I have dealt with in the past so I may well be barking up the wrong tree.

Thanks
