it would be helpful if you listed the model # and you don't need to more around the d: drive since that is your system recovery

The model is a Presario V4000.

The reason why I thought I had to move D: drive files was because the clerk at Best Buy said that was the problem. I'm assuming I wasted my money on the external drive, then.

here are the specs for it

Well, the problem I'm encountering when I do run a deep-scan virus program is that the fan starts to spin, really fast within the computer, and shuts off.

I know when I hear the computer fan start to spin, wildly, my computer is about to shut off. And it happens only when I'm on high-graphic sites or listening to music on my iTunes.

And it also happens when I run a scanning program like a virus program or simply using the "search" feature on Windows. Anything that requires the computer to scan files will cause the fan to turn on high and then the computer shuts off.

No one has any clue why this happens and I'm about to throw the computer away. I'm fed up.

It has a mind of it's own. The computer fan and the automatic computer shutdown are correlated for some reason.

On the free space idea: Lack of space would probably only crash things if it was your C: drive and you have less then 1GB free.
The free space on D: has no adverse effects on anything except that you may get a low space warning message. It sounds like the Best Buy clerk was a little clueless on how drives work and effect the computer.

How long have you had the computer? If it's within the warranty period you should contact HP and talk to them about it.

I'm guessing the problem is the termostat or lack of ventilation to you hard drive, lack of space in disk may also cause the hard drive heats up, leaving it on for long hours without use can also be a reason why it heats up, so when you finally try to use it the it will respond shutting down to control temperature, I know computers that run Windows XP with only 2GB and have no problem of shutting down (although they become really clumsy).. my suggestion is you only turn it on whenever you need it, give it good ventilation (even placing a normal fan behind your computer if possible will help it keep the temperature good..) you could get some software that help you watch your computer temperature.

Im thinking it is a hard drive manteinance problem... a really tough one...
Here are some arcticles on hard drive manteinance:

And please dont forget to turn it off if you dont use it within more than an hour.. (I tell you because one of my aunts used to keep her computer on the whole time and some day the hard drive just got fried!.. no computer shutting off, no anything, she had no time to save files or nothing.. so safeguard your files and take it for a hardware check)

Im thinking it could be your ram not helping with video settings could also be a reason for shutting down but I believe it has more to do with the hard drive manteinance thing...
