But sometimes it does not even restart, it stucks. (The most interesting thing in this problem is that it never happens in another country, only in my home country:) )
Any ideas about this problem? Thank you in advance...

lol stop errors only in native land. Now THAT is a first for me. Probably a coincidence or possibly network related.

Let's have a look at the crashes. C:\Windows\Minidump

Copy/paste the files in that folder to any other. Then zip the files. Attach the zip to a post using the paperclip above where you type, in advanced mode reply.

There it is, I have attached it.


Congrats lol this machine is a mess.

You have one of the most notorious drivers in Windows history, namely sptd.sys.

Uninstall Daemon Tools in the normal method. Then use the installer/uninstaller to remove sptd.sys from the system. See the page's faq if you need help with that. It's simple:

DuplexSecure - Downloads

Reboot and install PowerISO because the disc emulation part is free forever and it will never crash.

PowerISO - Create, Edit, Compress, Encrypt, Split, Mount, Extract ISO file, ISO/BIN converter, Virtual Drive


Update your Intel Matix Storage drivers. Use the link to scan, in the blue at top. It will install the latest Intel drivers. If for some reason it doesn't visit your motherboard website to obtain the latest storage drivers to install:

Uninstall any software shown at the following links that you have, so that the following old/problematic drivers are also removed:

Update your Dritek keyboard driver.

Visit the manufacturer's website of your wireless adapter to download and install the latest driver for it, to replace this old/faulty driver.


Visit your motherboard's website to download and install the latest Atheros Gigabit network driver:

L1C62x64 L1C62x64.sys Mon Jul 27 03:04:36 2009

Update this Winbond CIR driver:

nuvotoncir nuvotoncir.sys Wed Jun 24 08:03:39 2009

If you manage to follow all that, the machine will be well. Let me know if you run into any issues and we'll see what we can do about them. Good luck and enjoy.

there is a problem with scanning, it does not finish:), it is scanning more than 2 hours, I also have difficulties with Dritek keyboard update, where can I download it?

bah 2 hours? It supposed to be more like 2 seconds.

Use CPU-Z to find which motherboard model you have. Then visit the website from the manufacturer for it. Download and install the Intel Matrix Storage driver from there.

As for the Dritek keyboard driver; I can't say because their website only says something like "coming soon" for the drivers. I'd be very inclined to use another keyboard for now and remove the Dritek one. At least until issues are solved.

Have there been any crashes recently since making other changes?

My motherboard model is JM50-MV, but I can not find any sites related to it:)
There were crashes after other changes. Yesterday it crashed and I could not turn it on again. But today it is on:) Now I look at this directory C:\Windows\Minidump and it seems that there are more files. Is that normal?

I have had some crashes after changes. I have uploaded a new zip file. Today laptop worked fine all day after updating from the given link, but some minutes ago it has crashed again:(


Atheros Gigabit driver hasn't been updated yet.

You can update the video card driver from here - NVIDIA

Update the HD Audio driver from here: Realtek

There are lots of other things but I have to go for a little bit. Maybe Cybercore can help you with the rest for now. If he's not around, I'll post again in a little while.

I have returned laptop to factory conditions in order to get rid of these problems, but now I see that this is a factory problem. I did not install any drivers after returning to factory conditions, but laptop crashes again. I have uploaded a zip folder with files from this directory: C:\Windows\Minidump. Are these crashes similar to my earlier crashes?

Ouch. Restoring not such a wise move. All you needed to do was follow my previous post.
