All this talk about PC's running 24/7 has convinced me of the reliability of processors. It's been my thoughts that if your computer is on, it's always running at full speed, whether or not you're running Prime95. I've always left my computers on all the time, and never had a problem. This

Monitors, on the other hand, seem to like to be shut off regularly. At work, we bought 9 Nanao F750's 60's in 1993. Only two survive, and one sits on my desk and is turned on and off daily. Those that were left on 24/7 did not survive the last cycle of cpu upgrades. Ken At 01:42 AM 4/19/2000

Hard disk drives seem to last much longer if they're left running continously. I'd reccomend disabling "power saving" modes on HDD unless power consumption is critical (e.g. a notebook computer when running on internal power). However, HDDs often fail if they've been running continously for

Jeremy and I used to do that alot on those first generation IDE drives (which seemed to have this problem much more often) back when we were computer techs... It sounds funny, I know, but it worked great most of the time. If I remember correctly, it seemed to happen with certain batches of

I'm just curious really, but how durable are Intel processors to continuous number crunching, in other words has anyone been able to keep the same processor running for 2, 3 or even more years, on a 24/7 basis. I do realise that Windows itself needs to be rebooted from time to time, but what

Very durable. I have Original P-II/233's two years old still going, have been 24x7 since day one. I have P-166's that have been going for 3 or 4 years nonstop on either crunching primes or crunching DES. I even have a handful of P-100's, among the first original Pentiums, still going on
