17 DMP files is going to take some time. I am doing them now.


I only did the five most recent becasue the pattern has already become clear. These were all caused by memory corruption.

To test you ram I would download memtestx86, burn it to cd, and run it for at least 5 passes.

Code:

Thanks for helping zigzag3143.

I have run memtest86x 4.10 for 5 passes and no error. Tomorrow I will try to run test for separate RAM's (2 GB RAM at a time for 5 passes). Maybe test will give different results.
But for now, could be there any other problems, not with hardware?
I have already reinstall Windows twice 2 months before, that didn't helped.

Separate memtest for RAM was ok, no errors. All 3 ram chips passed it for 5 times.

ctoss2k.sys - I haven't found newer driver for my sound card so i removed it at all.
Now i will wait and see if everything is OK. Hope there will be no more blue screen.
It is very optimistic, coz there were some blue screen before i put this sound card.
Any more possible reasons for blue screens ?

One more problem with taskbar:
Sometime after booting windows, taskbar shows uo with stripes and after switching user stripes disapiers.
Also sometimes screen blinks and taskbar become all grey, and after one more blink(around 3-5 minutes)
tasbar comes back to normal. Any ideas about that?

Thanks guys

It's me again.
There was no bluescreens since i removed my soundcard.
But today i've got tree of them. About two first i didn't know nothing,
coz i was at work.
After third one Windows booted to welcome 'sign' and the screens show only black.
with Ctrl+alt+del i could see users selection window, but choosing user it shows only black.
After booting in safe mode, i managed to boot windows normally.

Don't know what to do. Is it windows problems, or is it my PC bad ?
Any recomendations ?

Also i noticed that my mouse became sensitive:
e.g. i click ones, but it somehow clicks twice.
I can't drag windows around, or even select text with it easly.
I'm going to buy new one, but maybe it is sourse or problem or smth?

Hi,

dxgmms1.sys is mentioned, so make sure you check that you have your latest graphics driver.

[nvidia][/nvidia]
However, given that system processes are blamed for the other 2 BSODs, there is still a faulty hardware component in there somewhere.

Does it affect the whole screen? Because a graphics driver is mentioned I think you might have a fault in your Graphics Card - update the driver first, just to see if it helps.

Thanks Reventon.
I have suspicious on my Graphic card too.

Today i'm going to take my PC to the store,
because yesterday i have got this Warning:
"The previous overclocking had failed, and system will restore its default setting."
After this msg Bios starts up, and after exiting it Windows starts up.
But windows works only for 2-5 min and very quick bluescreen (sometimes) and PC goes down.
And then trying to boot up gives no results. Procedure could be repeated olny after 10-15 min.

Will see what would they tell me, and what would they do.
