Now I will describe my problem.... 2 weeks ago first blue screen error apear.
It sad: DRIVER_IRQL_NOT_LESS OR EQUAL and some file has been written ALCXWDM.SYS!
Later i find out that this have some conections with my sound card. I thouth that my driver is too old and I uptade my driver. I installed Realtek AC 97 4.06!
But after couple of days there it was another message- again ALCXWDM.SYS! I was mad and I decided that I can live without my sound soI go in search and find ALCXWDM.SYS and delete it.
My computer was working just fine till 4 days ago when that new blue screen error message apear. It sad: Stack-Based Buffer over flow! I tell myself ok maybe this error cause sound error! I search internet and find out that Stack- Based Buffer error means that I have attacker in my system like spyware!!!!! I emidiately burn all music, pictures, and videos from my computer to cds, dvds. And for past 4 days this 2 blue screen error apears randomly and whatever I do on computer till yesterday morning when appear new mesage: PFN_LIST_CORRUPT.
I search forums for answer and read post from some guy named howard_hopkinso! He says that Ram memory is cause of all errors. There is some conection betwean ram memory cause and my case becouse I upgrade 1 GB ram memory 3 months ago. But I am suspicious about that becouse there are some time space betwean my ram memory upgrade and blue screen errors!!
Anyway my computer is old and it goes to garbage for 6-7 months but I would like to have some fun till then!
And I cant crush my windows becouse I have installed Windows office 2007 ORIGINAL full edition, and instalation cds my dad took back to his firm. And I have some other original full edition programs which I havent anymore!
My computer specifications are:
Intel processor- 2.02 GHz
Graphic card- ATI RADEON 9000 Family (128 Mb)
Mother board- Gigabyte GA-8PE667 Ultra
Ram memory type- DDR 1
Ram size- 1256 Mb (before upgrade 256 Mb)!
And I decided to join this forum becouse I think here are some smart guys who can help me.

Run memtest on your RAM. Read this link and follow the instructions: https://www.techspot.com/vb/topic62524.html
Let it run for a LONG time. The rule is a minimum of 7 Passes; the more Passes after 7 so much the better.. There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.
If you have errors you have corrupted memory and it needs to be replaced.
Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
* Get back to us with the results.

Ok, I run memtest, it was runing 2 days and 21 pass(2000 percent) and nothing, not a single one error. Then I go search net again and I find out that system problem can couse blue scrren error. Then I install registry easy 5.6 (full edition) and there was 1600 problems and I fix them all, and blue screen again appears. Then I install DriverScanner 2009 and scan my drivers and I find out 5 of mine drivers have been not up to date. Then I updated all my drivers. But blue screen appears again. HELP!!!!
I know that I am boring with this problem, but I read something from that guy from other forum. He saya that these errors could be caused by some programme in my system. Is it possible that this is not hardware issue? I am confused. In event viewer errors are there but some stupid NtpClient and number 0x80072751..... But that error is related with internet connection as it sad in description. But in fact, internet connection is only thing on my computer which work properly...

Do the following:
How to find your Minidump Files:

It is these files that we need (not the folder). Attach to your next post the five most recent dumps. Notice the Manage Attachments button at the bottom when you go to post the next time. You can Zip up to five minidumps per Zip. Please do us a favor and don’t Zip each one individually.

but to send private messages I need to have a quite number of posts, but I dont. As you can see, I am not some technician but I already do that stuff with my computer >c drives...... i FIND NOTHING, but I can do that again, and I will becouse there is past some time from my previous post. I tell you, this errors doesent harm my system and dont disturb me in some work but those errors are annoying. Thank you for help, keep posting some good advices here. If you can of course. I will come back with results.
oh, by now, they give me all kinds of messages. ALCXWDM.SYS, NTSF.SYS, some-klkd or something.SYS, memory dump, small memory dump, every time diffirent. You ask yourself why I simply dont reinstall windows? Becouse I install original office, and its expensive, and I must return that cd.s to my fathers company. And of course, office is on hard disk c where it is windows. I already wrote down here specifications, and these blue screen errors does appear every several days. Its not that often you know, but it does disturb. And I install everest. I go in event viewer and find only a couple of hundred warnings/errors (they are same).

No, you are most definitely NOT sorry for your rudeness because you went straight ahead and did it anyway.
First of all you have the audacity to complain but never mention once that you are infected, have a weak antivirus, etc. and then moan and groan because someone is trying to help you?! Am I perfect? In no way, but I have helped quite a few people here as have many solid people who are steady contributors and I'll be the first to admit many know more than I do.
It has been over two whole months between your last post and this latest ones with barely any information to go on, no minidumps and partial hardware specs. Seriously Vepar you gave little information to go on and truth be told it sometimes takes considerable effort and trial and error to figure out PC problems.
If you know you are infected why in the world didn't you mention it? What are we, mind readers? If you would have told me this extremely important piece of information I could have steered you in a whole total different direction.
I'm done with this thread. Someone else can come along and try to help you. I will no longer read any responses you may give to this thread.
