This is quite common with fast-clock systems on hot weather (I live in the Canary Islands:) Take the cover off from your computer AND STICK A FAN blowing into the motherboard, until you buy some FANS-IN-A-CARD or better yet an ICE-CAP or, in your case, get a new system under the warranty. I WOULDN'T run it with the cover off by itself without the fan (this can potentially fry your silicon unless your air conditioner works good and there is a nice breeze inside your office ...) I still don't understand why Intel (this particular problem might very well NOT be with an Intel chip) doesn't start selling the uP's with "Ice-Cap" type of devices already on and heck with the heat problem (if the fan fails, add a thermo-switch and just halt the chip, crude, but better than having the power supply break and the chip fried anyway). No reason why a well designed/built mini-FAN can't have 300,000 hours MTBF. At least put heatsinks as standard equipment (I know this is being done on some i486DX/50). BTW, I can't find where to get the following (which I need ASAP). Can anybody help? -Ice CAPs (for 486's). -Fans-in-a-card (cards with a couple fans that fit on a AT expansion slot). -Good heat-sinks for 486's (and other silicon). -Rechargable (plugs into the power supply) "eternal" batteries for the "CMOS RAM" (where the date/setup info is stored in AT's). "Speced" at +3.6 volts (or a little higher:). If you have names, addresses, or better yet phone numbers (non-800 prefered), I'll appreciate it. * SLMR 2.1a * Rafael.Ramirez@channel1.com from SPAIN!
