so if u seen my previous posts u will find that some of them are for crashin games... but now it has gone so far cause all of my games crash the same exact way .... but it differs for the time probably due to the graphics of each games the game are ...
prince of persia the two thrones
prince of persia iv
counter strike source
call of duty 4 modern warfare
splinter cell double agent

these are the games i play now but there more games that crash
(note : i pass all the requirments for these games except for call of duty 4)
(note 2 : i dont face any lag/slow motion for any game except prince of persia iv )
this is how they crash ... after a while colour glitches start which affects some objects turning them mostly to very bright green/yellow/purple then the game freeze and crash...
and 1 more thing the problem is increasin because from a while cod 4 used to stay for about 30 mins and css for 1 hr now css is for 15 mins and css is for 30 mins even more right now both of them crash like after 5 mins so what could be the problem ?? all of these games crashin the exact same way cannot be by chance ...

my pc spec :
cpu : 2 processors running - Intel(R) Pentium(R) 4 CPU 3.00GHz
ram : 2 gb
videocard : 6200 (265 mb ) [sucks xD]

so any ideas?

If not heat it is a bad graphics card.

You could test your RAM but I think it will show fine:

Microsoft Online Crash Analysis

okay i know its probably graphics card for cod 4 but i DO PASS minmuim requirments for these ...
btw : what u mean bad? u mean damaged or just not good enough to run these games?

Damaged.

bloody hell it has been with me for just 2 years
well is there anyway to make sure its damaged?
like a program or somethin that checks it

Not really. You can test other hardware just to make sure it is OK such as RAM in my last post.

You could also run this scan just to see what it says:

PC Pitstop: Free PC Scans and Tune-up Utilities

yeah well 1 last thing ... if it is overheated is there anything that can test the heat for the pc or the video card ? and if it is not overheated or sth like that what could have caused the damage? cause u know that i am buying a new pc nearly and its supposed to be with me for about 3.5 years so some tips would be usefull

looks normal?

Everything is normal but the CPU unless you have some refrigerated cooler.

Probably just a bad sensor as it would not be that low.

Monitor it while you play a game.
