i Had a GeForce FX5600 before this and played all the games i am currently having problems with.
after losing a stick of ram just after i got the card im stuck with 512mb of DDR2, i have my o/s running *OK* but not very well, it seems a little unsteady and freezes up alot and sometimes when im browsing the web and just playing music it will have a fit and freeze up or go into standby

i cannot play any 3d games, It freezes up when i enter the game(s) and if i do make it into the game i will see all the graphics of the game a short burst of sound and then it will freeze screen turns off ect...
Now i am leaning towards hardware incompatibility on this but the only hardware i have changed is my graphics card but my MOBO seems to support all the features of it.
My computer:
PSU: 550W generic brand (came with the case)
MOBO: Foxconn/WinFast K7S
CPU: AMD Athlon XP 2400+ @~2.0ghz
RAM: 512mb DDR2
Graphics Card: HIS Radion X1550 256mb 128bit AGP
Extras: 2X case fans
I have searched the web so much to find an answer but to no avail,
Now if anyone could help me out or give some suggestions i would greatly appreciate it.
thnx
