Z92T Crashing problem

So does anybody out there have any idea what it means if one has random crashing (computer works fine, but out of nowhere it just freezes randomly, could take 5 hours, could take 10 minutes, just curious as to what would cause that kind of thing)

I have a Z92t if that helps.

Sorry ive been so vague. I have two identical corsair sticks (they were not a mated pair though). If I try to run memtest 86 it just freaks out and restarts the computer (in single or dual channel mode), if I try the windows memtest, it passes all the tests, I will usually get a freeze when the system is under stress.

I am not using any antivirus.

And when I say freeze, I mean freeze, everything freezes, mouse cursor, everything, not just the program.

If I take one of the modules out, the computer doesnt freeze anymore. or to be more specific, when I take it out of the RIGHT slot it doesnt freeze anymore, even when i switch the modules. So my diagnosis tends to point in the direction of memory, I would say the slot, but before I had my laptop RMAd for a bad bios, it did the same thing (although not as often). So I must conclude its the memory, dual channel definately makes it worse.

What im guessing is that I just happened to pick the exact wrong hardware that doesnt to be with eachother (which ive had happen once or twice).

The exact memory im using is this:

I do have the latest bios version, ok, now what its doing is when I have the ram in one slot it freezes less but it still freezes, and now im getting graphical corruption at the top of the screen (tiny colorful dots, looks like dead pixels, but alot of them) but only when it freezes. Ah, I feel like im gonna explode here, usually I can nail down the problem quickly but this is something I am at a loss of words for. And keep in mind it did this before I RMAd it, and they replaced the motherboard, so I seriously have run out of ideas...

Also, id like to mention that the same exact thing happens whether I use my VISTA rc1, or my XP, I think its hardware, but im completely out of ideas.

Also, its never frozen in a game before, it freezes often during videos (divx) and when im playing music in itunes. If i dont do those two things, it takes a long time to freeze, but it still does. I know this is a retarded explanation, but I am completely out of ideas.

I just updated the chipset driver and cpu driver to the latest versions, and I have not had any problems yet, but im not holding my breath, the problem is random, completely random, which is something that really gets under my skin.

Oh, and thank you for trying to help me out ^_^

It takes longer but it still freezes. And again, when it freezes I get graphical corruption at the top of the screen. Does the Z92T have a removable graphics card on the main board, or is it soldered on?

I have seriously run out of ideas, It freezes no matter which piece of memory I use...I have seriously...run out of ideas, and before when I RMA'd it, it did the same thing, I thouight the mobo replacement would fix the problem, obviously I was wrong.

Any other thoughts?

Is there any good CPU diagnostic tools? I have been trying to find one but have been unable to.

Also I have another theory. Is the 7600 on this thing MXM or removable in any way? Because if I had the problem before my motherboard was replaced they might have taken the videocard out and put it in the new motherboard. I dunno, Ive completely run out of ideas like you wouldnt believe hehehe. Also, would a corrupt videocard cause the whole system to freeze? I dont think it would, its been my experience that they just crash when you try to do something stressful but you can still get out of the program.

I dunno, im ripping out my hair here....

Well, I tried all the diagnostics and everything checks out fine. Im just going to sell all the parts seperately and start from scratch, maybe an s96j or something, too bad too, this laptop was perfect for me...

sorry to burst your bubble, but I did upgrade the bios about 2 weeks ago, same problem. Taking the memory out of dual channel helped a little bit for me. Not sure why, but both sticks of memory test fine in other computers. This problem essentially makes no sense whatsoever. Ive had my unit replaced twice and it still does the same thing, and all my parts test fine in other computers, so really ive ran out of ideas, I really am thinking wrong combo of parts...thats all thats left really. Also this bothers me especially because its my job to repair computers for a living (technician).

I repeat, updating the bios doesnt work, I just have a pretty asus logo now, but still crashing heheh. I tried the modified nvidia drivers and then I tried the default ones, with the same result. However, if all the hardware tests out fine, it could be a driver conflict...considering there are about 16 drivers on this thing...and some drivers are poorly made, it could be what it is, but...not certain

Also, I have the vista RC1, does the exact same thing in that. and im having the same problem as in2tactics, it freezes quick during video, takes a long time for web surfing, and doesnt freeze during games (wierd symptoms huh?)

And when I say crash, I mean...MEGACRASH, mouse curser not working and last .2 seconds of audio repeating over and over and over again kinda crash.
