Random BSODs on a brand-new PC (ntoskrnl.exe)

carwiz said:

Do the bug checks begin right after starting the PC or after the system has run for a while?

Most of them while running for a while. Sometimes when rebooting from a BSOD it crashes again after Windows logon.
Remember having BSOD at the very start only once.

I know you tested the individual modules but have you tried running with just one module? You might also try cleaning the memory module connections and slots.

Did all of that.. Had BSOD also with each stick separately.
Tried cleaning, removing dust...

Verifier itself didn't actually catch anything, but one thing I noticed was the Nvidia 3D control panel item showing up a lot. Do you have a 3D setup? If not, have you considered uninstalling the 3D portion of the Nvidia drivers if possible, or at least disabling them?

Never used it. However, at some of early Windows installs, I left 3D Vision unistalled, and the problems persists.

Other then that, the only other item I see frequently coming up is some Pokemon Tradein application. Unfortunately even the DV crashes aren't showing anything of worth, which kinda leads me to believe that we aren't dealing with a software problem but a hardware problem, which has been my suspicion since the beginning.

I'm believing in hardware problem, also.
Just don't have any ideia of which one.

Took RAM sticks for RMA today.
They asked me a maximum of 2 weeks for a reply after completing the tests.
Trying getting another DDR3 stick with a friend of mine, probably tomorrow.
(If he had just told me earlier that he had a DDR3 to spare..)

May take CPU for RMA at Wednesday.

Running with friend's RAM.
Let's see..

Make sure his RAM modules are compatible with your motherboard, otherwise you'll run into another mess of problems.

Checked before, are compatible.

Still running with no crashes yet.
I'm not confident it will last long, though

I'll let you guys updated :)

Still running with no crashes at all with friend's RAM stick.
However, with my RAMs at RMA, I could run the system stable for more then a week once.

Can a RAM be with "problem" even with memtest86+ not showing anything running for 10 hours?

Diagnostic software can only go so far. Even Memtest - as thorough as it is - can only do so much in testing the RAM. There's perchance a possibility the issue lies not in the RAM itself but the crosstalk between RAM and the CPU or another device using DMA (Direct Memory Access), in which case that would implicate the motherboard more than the RAM. Hardware problems are rather difficult to evaluate through software methods, so often times it ends trying to isolate potential items of cause and then just swapping hardware and hoping for the best, like now. I hope it's the RAM we're dealing with and not the mobo!

I'm back with some news.

Passed 25 days since took RAM kit to RMA, no BSOD at all.
Tested with:
1 x 4gb Markvision 1.5V 1333mhz Single channel for 15 days
and
1 x 4gb Kingston Hyperx 1.65V 2400mhz Single channel (same as mine) for 10 days


Yesterday, the store gave me a NEW RAM kit.
Took it home, placed both at the machine.
ONE HOUR running the system, it crashed, BSOD.

Seriously, what the hell?

Motherboard warranty 10 days left.

Uh oh. I'd take that motherboard out and RMA it asap before that warranty expires skipper, if just for the fact that its warranty is about to run out.

That or of course, the mobo just doesn't like the RAM you're feeding it (either it can't handle the amount you give it of that particular model or the mixed setup), in which case no amount of RMAs will fix it outside of requesting a refund and getting another mobo that will accept the RAM better.
