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.
