Testing Hardware?

Heya,

Somehow just now the computer made a really weird noise and then it shut down. On the next reboot (a minute later) I got "Disk Boot Failure" and I was asked to place the "system disk" and "enter"

So I shut the computer and checked the connections to the hard drive which were all intact. So I just unplugged and replugged it back on. Now I'm on the computer again. I'm kinda scared that it might be failing and it's time to back-up the files (my secondary hard drive has already failed and it takes to long to format so I haven't gotten to it... long story)

Anywayz is there a device to check the hardware's health status? BTW I have win xp home and it's a tragic media center

Would appreciate any help and thanks ahead

Jam it back in, in the dark.

I'm a SHE!! >....<

Anywayz thanks I'm in the process of backing up my data... so a "smart" test huh... I'll look into that (dun know what it is) but I'll see how to work it

There's nowhere I can't reach.
