Graphic's card problem

I have been having problems with my Radeon 9550 256 mb graphics card
made by Sapphire. Sometimes when im browsing the internet, i notice
that when i click a link, or on a picture, the screen goes black
because it is not recieveing a signal from the graphics card. I know
that because shortly after a "no signal" msg is displayed. Then i
began to download a few games from my direct to drive account. The
first game i had trouble with was swat 4. When i finneshed installing
it and attempted to play, i nocticed that loading took long for an
AMD
3200+, 2000 MHz, 1 gig ram computer. When the menu finally came, all
the text was disfigured in the sense that they would contantly be
flickering and changing. The background picture was fine. Then when i
tried to play a game, it would take its time to load, again with the
disfigured text. When the game would load, it would usually play for
about a minute and then freeze. Then id have to restart my computer.
this happened every time i played it, and my computer had more then
the minimum hardware requirements to play the game. I then downloaded
Return to castle wolfenstein, and when attempting to play the
multiplayer game, the computer would freeze, and the screen would go
black because there is no signal. While this was happening the
background music would continue to play for about 30 seconds more,
then id have to restart it. Then i tried with Star Wars knights if
the
old republic, and this time there was no disfigured text, but all but
the quit option on the menu would appear. when i tried to play the
game, it would play for a while, and then go into the same state,
with
the monitor going black because of the graphic card. My mother board
is not more then 4 months old, and my graphic card is even newer. I
tried downloading the new driver, but it wont install due to an NSIS
error. Can anybody help please?

Thank you for replying, i felt the graphic card, and it doesnt seem to
be overheating. i did just downloaded Speedfan, and it five different
reading. One of them is the processor which seems to vary from a arrow
pointing in both directions, to the check mark. There are three with
the down arrow (dont know what that means), and one with a fire sign
lol, and is given the name Temp 3. How can i identify what hardware
component the software is monitoring?
