Graphic Cards Sapphire 4670 problem

[rachit05]

my config is the following:
Processor: amd athlon x2 7850 be
Motherboard: biostar ta790gxb
RAM: Kingston 2 GB 800Mhz DDR2
HDD: WD 320 GB
Montor: LG crt 17'
Graphix Card: Sapphire ATI Radeon HD 4670 512 MB
OS: Windows XP service pack 3

Now the problem is that when I play Batman Arkham Asylum and reach a certain point or randomly after sum tym-- the graphic card goes blank the monitor displays "No signal"(BUT SOUND IS STILL COMING) And whatever I do the system cant be restored. I then have to restart the computer.But the problem is that I can play games like crysis, gta4, cod4, cod5,prototype, shift, burnout ,etc,, easily widout ne such error

and i donot have a bad game copy as two of my friends have the same problem (they also have the same cards) and they have different copies.

i have tried updating drivers, switching to old ones,
but no gain

PLEASE ANYONE PROVIDE ME A SOLUTION FOR THIS PROBLEM!

Strange error, have you tried updating the game? And you say no such error on other games right?

If you have a legit copy try contacting the game tech support.

[mod]please avoid any references of piracy[/mod]

@rachit it seems like a game related issue, try googling and check if any one had a similar issue.

this may happen if the key is blacklisted.
for instance, LOTR 2, you can play the game, but it would automatically shut down the game and come back to windows in 3 mins.
