Blue screen Stop: 0x0000004e error

[heatherrnw]

For a couple of days now my system has been blue screening. I ended
up reinstalling the whole system and thought that it was the graphics
adapter since it ran fine until I ran a heavy duty graphics game on it
and it blue screened again. It seems to work fine until I start that
game. I have traced the code and finally understand that with all the
peramiter codes that came up the problem is a page table entry (PTE)
or PFN is corrupt. What I don't understand is how to fix this
problem. I am not knowledgable in fixing things like this and this
has been a total learning experience for the last few days now. Is
this something I, or my husband who DOES know how to fix this stuff,
can do ourselves or is it time to throw in the towel and take it to a
pc repair shop? If it IS fixable by me, what do I need to do to fix
it?......and I don't have a floppy disk drive to copy anything (read
that on another page).

Try to uninstall the game, and see how your system is performing,let us know. The game software might be creating problem for your display.

I would run memtest and test your ram, when i had stop errors like this my ram wasnt seated right, since yours isnt a new build maybe you have a bad ram module
