GTA 4 PC Problem

[abhineetnazi]

I am running Windows XP 32bit with the following config:
Athlon 64 3000+@2.51 GHz
2 GB DDR2 RAM
Radeon 4670 512 mb
GTA 4 after running for 5~10 minutes crashes to the desktop with the following error:
RESC10 Out of video memory - Please re-boot your system
I have tried running it with everything at lowest settings at 1024x768 but the error still persists.
This problem does not occur in Vista though it runs much more smoothly in xp than in Vista.
Also when I try to exit the game I get a black screen and nothing happens.I have to shut the game from task manager.This problem occurs in both XP and Vista.
I have got patch 1.0.2.0 installed and am using Catalyst 9.1
Please suggest a solution.

i am not sure, but a single core cpu is far lower than the minimum requirements for the game and the 4670 is not all that great either, though much more powerful than your cpu to say the least.

If it was a hardware problem then why would it occur only in xp ?
