Video Card makes squealing sound?

[BarneyGumble]

Every time I quit CS:S without first diconnecting from the server, my computer hangs up and i hear this terrible squealing sound comming from my case, I'm assuming this is my video card making noise, it's not the fan, it only makes this noise during the operation mentioned previously. Should I be worried about this?

Check all fans. With the PC off, see if they will spin easily by hand. Next, I would check the power supply, if not, reload your drivers (video, chipset, etc.).
