I recently replaced my Dell Dimension 5150's hard drive with a WESTERN DIGITAL Caviar Black 640GB SATA II 7200 RPM 32MB Buffer Hard Drive. Now I hear the fan reving up like there's a cyclone in the machine, especially when I insert a DVD, let's say, to search for pictures or a CD to rip music to iTunes.

Is my new hard drive overtaxing the power supply or is the noise an indication of something else (dirt, need for lubrication?). I'm not even sure if the powersupply fan is the culprit. Could the fan on the video card I installed --an XFX PVT84JUSD4 GeForce 8600 GT 256MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI--be the bad guy? Might it be the CPU fan? Who knows?

I was considering replacing the power supply with a 500w or higher one but I'm not sure if this would solve my problem or if it is even doable or worth the costs.

I would appreciate any advice.
P.S Would it matter how many 12v rails I got if I did replace the PSU? Also, are there any good online tutorials on how to do this?

Online tutorials to do what? Best suggestion I have is to take out the video card and try running the computer without it; if the noise is gone then you obviously have your culprit.

Given your specified specs, I don't think your PSU is overtaxed. Compared to other components, a hard disk consumes considerably less anyway, even when running at full speed.

The 5150 should be a mid tower case, capable of installing a ATX PSU.
