well the BSoD occurred even before I have done anything to the laptop.

Recently I do not receive any errors. Usually if the problems begins..it occurs for 3-4 days then I just start to find out what's the problem and the problem would be gone for a while. Could it be actualyl a heat problem if that's it then its just way to frustrating...

Ok, I can only repeat what I have said about there being a loose connection.

The fault that appears on screen is cured by shaking the PC so that more or less proves there is a loose connection. This would also explain why the fault is intermittent. Your temp read out is normal so it is not going to be a heat problem unless the fault occurs when you have the laptop in a position where the vents are blocked.

I would point out that shaking the PC can damage the hard drive so it is not advisable to continue doing this to correct the fault with the graphics.

I'm giving as much advise as I can and asking questions which you have not replied to.

Have you tried any of the recent suggestions I have made?

Unless you take some positive action using the suggestions I have made we cannot eliminate anything as a likely cause in order to track down the fault.

First rename the USB 3 driver and see if that changes anything.
If the problem persists re-enable it.
Then strip down the PC and reseat every connection.
If you are not comfortable re-seating the connections which can be a delicate operation I would suggest you take the PC to a recommended repairer.

There is nothing else I can suggest until you start to perform some diagnosis.

I did rename it and no errors occurred since for now. As I said the problem would happen only periodically so now I belive it will be fine for a while.. I'll report the future events later thank you.

Your welcome, let us know how it goes.

Ok, it happened again..this time while watching youtube.

Today I pushed my laptop a little bit: I played games, watched lots of videos, and then again the screen had some yellow lines, which was fixed by just picking it up, and hours alter it froze again with the same "ehhing" noise.

No minidumps again. Maybe it requires some options to be fixed to throw error logs?

This is the first time you have mentioned a noise coinciding with the screen fault, I have no idea what "ehhing" sounds like. Please discribe using more descriptive words, squeak, buzz, rattle, click, high pitch, low pitch, etc. Or compare it with a common noise that we would all recognise.

Unless the noise is coming from your systems speakers then we are probably looking at a faulty fan or hard drive.

like this

Is that video showing the same error message that you see on your screen?

I don't hear any noise on that video other than buzzing is that what you hear?

Try the troubleshooting steps in this guide: http://www.tech-faq.com/nmi-parity-check-memory-parity-error.html

As I have already suggested you most likely have a loose connection so all the internal connections need to be reseated to eliminate that possibility.

I do not have any error messages, it simply freezes and restarts. I call it BSoD, because the earlier similar errors would have thrown me an error log which indicated it as Blue Screen.

I will try to fix the loose connection problem and then come back with he results. thanks.

Is it possible that I am overclocking my LapTop? I used 2 browsers today and each had like more than 15 links, and it froze when I tried to download a torrent... which program I can use to see specific details of my errors?

ok, i guess the log above is not really related to the major problem...

The log above does mention PCI Express which is related to your graphics.

Just to put the record straight a BSOD is a blue screen of death and always shows a blue screen and creates a minidump file. When the system just freezes and reboots this is more like a power failure and does not produce a minidump. Overclocking is when you increase the voltage or frequency on the CPU or memory to increase it's speed. You cannot run too many processes and that should never cause a problem unless there is a hardware fault which is often caused by faulty RAM. All that will happen when running a lot of processes is that the system will slow down.

Mind how you go checking all the connections. While you have got the laptop apart try and locate the other RAM module, some laptops have one hidden under the keyboard.

I still think you might have a failing graphics chip and should contact the manufacturer to see if your PC was made when the faulty Nvidia chips were in production. I mentioned this back in post 12 but you made no comment.

I will consider this when I will go to the manufacturer center.
