I run my IBM 24/7 for four years plus now, and have no hardware problems, IBM if
it's one of their  high end machines, work well without incident for many years.

I hope to get a few more years out of it until I can afford a new 64 bit
computer.

That may take awhile, they'll be costly, for a really good machine.
