sounds like a dying piece of hardware, possibly a hard drive or a fan.. Might want to take the side off the case and see it you can narrow it down.

Typically a virus wont cause a noise, unless of coarse it was designed to open an optical drive.

How longs it been running? Have you moved it recently? Is there any USB hardware attached to it?

When a hard drive shuts down, the heads zip to the inner tracks and may cause a slight thump as the control arm bumper hits its stop.
Check the energy control settings of the control panel concerning the hard drive. If 'maximum' efficiency is set, that could cause the hard drive to shut down after only a few seconds of inactivity. This can cause excessive wear on the heads and platters, shortening its life. Best is to have it run continuously, only shutting down when the system is shut down. For laptops, of course a 'maximum' energy savings is desired.
"Never shut off" is the best choice for a hard drive, and "after 5 minutes" for a blank-screen process. A screen "saver" is no longer required, with flat-screen LCD types. Best that the input video signal goes off, and the monitor will turn off its display after a bit. Saves the backlight tubes from dying too quickly!

Hi I opened the case and i see the 300 FSP GROUP INC psu cooling fan not runing. Looks like a cheap power supply? I get on the net every nite for usually 1 hr and also make a few slide slide shows. I like the intel i3 core with 8 gigs memory runs fast

Power supply needs to be replaced if the fan is not running (or you need to be frugal like me and rip it open and replace the fan :P).

The other thing you are taking about

usually this is a hard drive dying. I would back up your data after replacing the power supply, and run hard drive diagnostics. You may have to replace your hard drive.

If you need help with running hard drive diags, let us know what kind of drive it is.

Could be a bad PSU... Causes low power output which may cause the clunking on the hard drive. FSP are terrible and are a cheap option in all the prebuilt machines... As Evasive said, replace now....

Some PSU models may have a fan control.. merely for the sake of being quiet. But if the fan does not run, then heat can build up too quickly!
With power removed from the PSU, use a toothpick to nudge the fan blades. If they jiggle to a stop, all is good. But if they coast to a dead stop, the bearing lube has dried.. and either the fan needs to be replaced, or relubed.
The same applies to any small fan in a computer system. Those fans are the 'brushless' type, using only a servo motor core to spin a magnetic ring. They cannot tolerate friction.
