It maybe that we are looking at a motherboard problem, however that is I think the more unlikely of the possibilities.

On the evidence that we have, although no really reliable tests have been made on the PSU, we can as you have replaced it discount the PSU.

The same applies basically to the graphics card, as you have replaced that as well.

Memtest passed you reported on both sticks testing ONE stick at a time on all 8 checks of the ONE cycle, and GOOD as Memtest is, it DOES not categorically mean that the ram is perfect.

We have as far as possible eliminated any question regarding the graphics drivers insofar as we have tried an older certified driver and now the most recent offered BETA driver.

NOW we have errors that we did not have before, not only when you are loading that game League of Firends but simply whilst browsing AND more concerning one of those errors is now related to the USB Hub.

Modern PSUs can ONLY be tested using specialist equipment, the old idea of testing with a multimeter, is a non starter.

I would recommend the following BUT ONLY ONE step at a time and testing after each step.




1. Run this please
http://www.geekstogo...er-by-oldtimer/

BE AWARE PLEASE that when the program runs there is a small flashing graphics on the top right of the program window.
The reason I am suggesting this is that according to Pitstop you have 5Gb of temporary files.
It will not solve the problem, but it is certainly of benefit to clean up a little.

2. Run this please using ALL available troubleshooters
http://windows.micro...ting-in-Windows

IF STILL NO SUCCESS Please proceed to the steps below



1. YOU check that all connections to the motherboard including the main 24 pin from the PSU and the 4/6 pin are properly seated and the clip of the connector is in place. That the SATA power connector to the HDD, the DVD (if that is SATA as well) and to any other hardware are also properly in place. You should of course include in your checks all the connections to the various headers - the USB, front panel Power and audio etc. Please also check the SATA data cables.
I am sure you do not need me to remind you but where these connections are on the edges of the board always of course support the edge of the board when disconnecting and re connecting.

Generally it is NOT a good idea to disconnect and reconnect as of course it simply serves to weaken the securing slots into which the ram and the graphics card and many others insert, but in your case, I think it is vital that ALL connections are checked.

2. If you have SPARE SATA data cables I would replace the one to the HDD especially as it WOULD not be unknown for that to be the problem.

3. IF you do not find anything immediately obvious and the problem continues I would then test with just ONE stick of ram. I cannot remember NOW if you have actaully done that.
I am not refering to MEMTEST but to RUNNING the system.
IF that still produces the errors i would test WITH the other ONE stick.
If that still produces errors I would return to both sticks.

4. I would then enter setup and load DEFAULT settings.
You may wish to take the precaution here of SAVING the current BIOS setup to the HDD - see your motherboard manual as to how.
TEST with default settings
IF we have hit the jackpot and I think it is a rather LARGE IF, then of course at least we have identified the posible cause.

5. IF THAT still fails, when you mentioned earlier that you have at one time replaced the thermal compound/paste on the CPU please see THIS
http://www.geekstogo...rface-material/

That is a guide written by Digerati a GeekstoGo Staff Member and one of our experts on PSU isuues and thermal matters.
At this stage, I believe it worthwhile that you consider this, not necessarily JUMPING in to replace it, but to ascertain if your previous method met with these guidelines
The common mistake is TOO much paste.
If you have doubts I would attend to the issue and test again.

6. I would if you have reached this stage with no result consider the suggestion in my post 27
http://windows.micro...de-in-windows-7

This if it configures correctly will go someway towards proving if this is all caused by driver or programs non compatability to windows 7.

7. If it is still NO success please post and I will re consider the position.

Ok, thank you for the steps. Since many of the steps require physically tampering with the computer, I will wait for the weekend to begin those steps.

One thing though, is it possible that it is a video card hardware problem? I replaced my power supplies with the Corsair, but I have not replaced my video card. Is there a test program that tests video cards?

Thanks,

Jon

Firstly may I apologise I read the thread as you had replaced the graphics, I realise this was MY error., as you said you had updated the card and motherboard drivers and replaced the PSU

I DO NOT believe all your errors are caused by a faulty card.

I have very little experience of these utilities and ONLY what I have read. I have NEVER used them.

In my opinion they are very like testing ram, but with more dangers possibly.
There is no more reliable test than trying another card, or trying that card in another computer subject of course to suitability.
Just as we always say that good as Memtest is, there is no test more reliable than the physical test.

YOU MUST CERTAINLY keep a close eye on matters as it is I believe so easy to cause damage if you allow the test to continue when there are signs of CPU and/or GPU being stressed to limits.

Here is just one
http://www.sevenforu...st-furmark.html

Here is another
http://www.sevenforu...-test-occt.html

and here is a link to the Nvidia forums where there is a wealth of information regarding tests and the 200 series cards
http://forums.nvidia...p?showforum=200

YOU can if you wish of course find many other tests just by googling it.

HOWEVER I WOULD URGE CAUTION in running any such test, as the extra stress on the components and I am still not convinced it is the graphics card, may well just be too much for them.

Hello,

I have been running my computer with only 1 stick of memory and have not received a crash yet. Of course I need to test multiple different scenarios and then swap out the 1 stick of memory with my other stick, but so far it looks promising that I haven't been able to replicate a crash yet with only 1 stick in. Obviously I do not wish to only have 2 GB of memory on my computer, but is it possible that the crashing is caused by the dual channel memory? Is it more stable to have memory not in the same channel if I still want to use 2 sticks? Since I tested each memory stick with memtest, I would believe that both sticks are good (and Corsair is supposed to be pretty reliable), is it possibly a motherboard issue?

Thanks,

Jon

MEMTEST is generally reliable but as I said there is nothing to beat the actual physical test.
Corsair is good and I use it.
I have 2 x 2 Gb of Corsair in this computer.
Depending on how old the ram is, you will find Corsair helpful.

I would now change the one you have for the other one.
If it crashes, you may very safely presume that the second stick is faulty.

I have worked on a number of threads and have now just forgotten if I have the exact make and model of the computer I will check the thread while you test the other stick and then I will post back

I was just about to sign off so I will check further when I return, but this is the list from Intel for the i5 processor.

http://www.intel.com...-datasheet.html

The ram you have is here
http://www.corsair.c...3m2a1600c9.html

and unless I have missed it and you should check, as I have only glanced, that ram is NOT on the list
1600 latency 9.9.9.24 1.65v

I NOW recommend you email Corsair and Gigabyte support. They will without doubt supply the answer.
AFTER of course trying the other stick and then trying both together.
I have NOT examined the manual, but you want one stick in DDR3 - 1 and the other stick more than likely in DDR3-2
but I am sure you have already checked that - whatever DDR3-1 is ie white or Blue the second stick will be in the SAME coloured slot.
That will be one stick in EACH channel.

If it does crash with the two in channel 0 then -
You could of course try populating the other channel instead, but that is not of course the way it should be run with just two sticks.

I tend to think the answer lies with the Link to the Intel i5 compatability chart

[icee]

I think it is on the memory approved list.

http://www2.corsair....aspx?id=1330346

Also on their forums

http://forum.corsair...ead.php?t=84832

I found another thread that doesn't have the exact same problem but has a very similar config as I do.

http://www.tomshardw...-mermory-issues

I did some tests and while I haven't done as much testing as I wish, it looks like there may be an issue with one of my memory slots. My motherboard has slots DDR3_1, DDR3_3, DDR3_2 & DDR3_4. Slots 1 & 3 are dual channeled, same with 2 & 4. If I only have 2 memory slots, I am supposed to only slots 1 & 3. When I only have 1 stick of memory in slot 1, it works fine even if I switch out both sticks. When I put a memory stick on slot 3 however, I freeze. Right now I am in slots 1 & 2 and haven't experienced a freeze. I need to do more testing, but it looks like I might have a bad slot.

However, if it is a bad memory slot, I would still be curious to why it only freezes on a very specific set of tasks and why it wouldn't cause more issues.

Thanks,

Jon

I do NOT agree

I think it is on the memory approved list.

depending on what you mean by the approved list.

I have checked again and it is NOT on the Intel list.

I have also checked the link your sent
http://www2.corsair....aspx?id=1330346

and it is NOT on the guaranteed list. All memory on the guaranteed list is 1.5v

It is on the compatible list.

Additionally to that I have read many of the posts on the Corsair forums and it is mentioned a number of times that it must be set up to run with the user configured settings and not the default settings in BIOS.

It seems to me from what I read that the answer is this
Specs: CMX4GX3M2A1600C9 1600 MHz 9-9-9-24-2T @ 1.65v <BR itxtNodeId="298">CPU: Intel i5 750 2.66GHz can run 1600 MHz ; it's borderline at 2.66GHz + 1600 MHz RAM

and the solution APPEARS to be the advice offered on the Corsair and the other link you sent.
to configure the special settings in the BIOS. for the XMP disabled and the voltage and dram timing manually configured.

HOWEVER
It is not appropriate for me to advise you on this, as it is not a subject on which I have a great deal of knowledge.
When I build a computer and I have only just completed the one I am using now, with a Gigabyte board I only ever use the standard recommended ram, from the list on the motherboard/processor site.
Therefore I have never had to alter voltages, timings etc from the default settings.

Possibly you could try as above and from the Corsair link you sent. If no success I would as I said contact Gigabyte and Corsair.
