BSOD, irratic, stop:0x0000004E

Erratic BSOD errors, once I isolated the problem to Windows Live Messenger and terminated the program but this time not, computer repair store have ruled out virus problems or hardware problems but can not find the software problem.

I always ask for your sake please create a restore point before altering drivers. If you don't know how to create one then please follow these instructions

System Restore Point - Create

We'll leave it at that for now.
Let us know how it goes.

Never mind TheDoctor44, I figures out how to update REALTEk though the device manager! Lets wait and see what happens (I am guessing that the problem is AVG, I have had problems with it in the past)

Ok good :)
Let us know the results.

Oops, just ran a Driver Updater Checker and it tells me that my -PCIe GBE Family Controller- is not updated, what do I do once I arrive at the url?
Realtek (Realtek)

Download the appropriate driver for your windows version.
4th one down on the list.
Make sure you have created a restore point

Done, I have downloaded it, how what do I do next, there is no exe file or setup file to click?

What files are included? You might need to extract it if it's in an archive.

files included are: note [text], rt86win7 [security catalog], rt86win7 [setup info],rt86win7.sys [system file], RtNicprop32.DLL [application extension], RTNUninstall32.dll[appl. extension] I have clicked on all of them, but nothing seems to autorun?!

That is strange, it normally works.
Try updating it via device manager see if that works.
