Blue Screen Error

[ECGxBlitZ]

Ok just installed PR to my pc With a
Dell Pentium 4 processor
2.66 GHz
6 Gigs of ram
Nvidia GeForce 6200 video card
and stock Dell 2002 sound card

My problem occurs when i signed into a lobby and started playing it seemed like when i was on a high vantage point and looking far away my fps dropped to 0.2 frames per second and was basically unplayable so i suffered through it for a while trying to snipe and recon from a distance and all of a sudden my game blacked out and my PC went to a blue screen with white text like C code but had an error report above the coding saying something about virtual memory or memory in general. and it said something about deleting files so i panicked and shut off the computer and restarted it without any problem and so i deleted all three PR install files and haven't touched it since. can anyone hep me figure out what happened and how i may fix the problem without spending bazillions on new drivers and video cards and such.

The error code can usually help you verify what your problem is. It is vital to write it down to be able to search for it.

Where did you get the PR installer files from?
Get them from here: Project Reality : Realistic Gaming Redefined - Downloads

Your GFX Card is below what I consider minimum requirements for PR. I had issues with FPS with my GTX 7900. It is possible that your GFX card is hitting its limits and starts to overheat. Make sure your temperatures are OK when playing games.
