Basically I have a user that complains about her PC being loud but everytime I get there it's quiet. So I want something to simulate it working hard so I can see what the noise problem is.
This will stress the CPU and harddisk. If you want to stress it more; simply create additional copies and run them all at the same time....
Quick, easy, free and painless....
Had a similiar problem once with a client and it turned out that walking on the wooden floor next to the PC made the wires inside touch the fan. So I tied up everything nicely and moved it onto a desk. Problem solved.
