I have an Nvidia 9600gt low profile by Galaxy; currently fitted to a Dell 531s only other change i made to it was to add 2 gb extra RAM
the total power draw is less than 250W I have had the computer for 3. almost 4 years now;
Recently i have purchased and installed this Galaxy 9600GT low power low profile card
Its been excellent for 8~9 months; even played crysis warhead with a mixture of settings mid and high at what i considered playable;
but for the end of that ninth month and all of this Jan (10 months owned this card so far) the fan has been cracking up
The fan spins in a sort of AC voltage style; like it goes zip then stops then zip another cycle and stops again; this happens until the computer is fully booted; After this, the fan is perfectly (seemingly) normal; and i get the temp readings at 57 degrees C idle with low fan (15% auto ) and 47 C at full (100% fan) when Im not using any intensive applications (aka IDLE).
the last few boot up sessions the fan stopped completely while computer (booted up) until I gave a gentle boost with my finger;Once this didn't work so i just shut down the computer manually to prevent overheating.
after the computer is fully booted though, the fan seems to work properly.
I have no idea what is going on and how this is going to affect my GPU
I have experienced a sudden performance drop when playing League of Legends once (last week from the date i posted this message) from 45-50 fps to 10/11 fps... which was strange; not sure if the GPU took a hit (got heated up)
im running vista 32-bit ultimate.
(ps by boot up i mean start up.)
help would be greatly appreciated; don't know how much time i have left.
luckily there is a 2 year warranty --- but im not sure what the best course of action is.

Have you tried cleaning the card? Drivers?
If it is not electrical then it is the fan bearing. WD40 on the fan bearing will easily solve that problem.
