Asus K50AB: Blue Screen Issue, Windows 7 Installation, Data Transfer, BIOS Update, & RAM Test

Hello
I am new here. I have a problem with this Asus K50AB, after 3.5 years, Windows finally sat down
Wanting to turn it on I jumped out a blue screen, so I downloaded the data to the second computer via a USB pocket. When I downloaded everything I mounted the disk and start to format when loading files again jumped out this "blue screen" after a few unsuccessful attempts I decided to mount the disk in the pocket and format it through the second computer when I formatted it and mounted the installation Windows started normally and then everything was ok But unfortunately after not a whole week the problem appeared again but now the format through the pocket did not help. I did BIOS updates and nothing helped. I thought that the problem can also be through RAM I have 4GB in it (2x2GB) so I tried on one bone and then on the other and unfortunately all the same time. The laptop had Windows Vista Home Basic and after the first format I installed Windows 7 Home Premium.
 

Buddy check the disk with a crystal disc program if it's working. This may be the reason

The disk is not the cause. Have you checked if it's the memory of the memory ???

I changed bones because I own 2x2GB and it did not help.

Try to change the bios to "older" it can help

I doubt it's a good move. Check mem with memory test. Original tile?

Sometimes it helps

Changing the Biosu on the elder did not help anything, and on the newer one too, I do not have too much memory to check.

download program Memtest is booted from a CD or pendrive

Today, I got a 100% efficient RAM chip and another disk also working. Unfortunately, all the time the same. Helpers.

It seems to me that the processor or motherboard sits down, I had a similar problem only that with a desktop computer as I installed XP only helped me to replace the processor and capacitors on the motherboard.

Unfortunately, the site stated that the motherboard went.
