- My 386SX/20 system has been crashing in unrepeatable ways recently and
- the pattern suggests something is overheating. Here's a detailed
- explanation of just what the problem is; I don't want to leave out any
- details that might be important.
-
- The problem only occurs after I've been running my computer for some
- time. If I just press the reset button, the computer reboots
- normally, but within a minute or two usually crashes again, in a
- different way. If I leave it alone for an hour, then reboot, it works
- fine, at least for a while.
-
- The errors occur in many different ways in different programs, and
- sometimes don't cause the program to crash, but if I then run another
- program, it usually gives another error or crashes. The programs that
- crash are usually or always reading data from files and sometimes they
- indicate errors in the input data and sometimes they just lock up the
- computer. After I've left the computer off for some time, these
- programs run on the same data without problems. Occasionally I've
- gotten cross-linked files and such after crashes.
-
- Programs that I run for a long time without reading or writing the
- hard drive, namely communications and an editor, never seem to crash
- except at startup, though my editor did once scramble parts of a file
- while it was writing it. A once ran Norton's Disk Doctor on the hard
- drive, repeating all tests over and over, including a long surface
- check, and on the fourth or fifth time it found some cross-linked
- files. When I turned the computer off for a while, then ran the Disk
- Doctor again, everything was fine.
-
- Also, though this is just circumstantial, when I've left my window
- open to keep it really cold in my room, my computer hasn't crashed.
-
- This all suggests, of course, a problem with either my hard drive or
- controller. It's an 80MB IDE drive from Western Digital with the
- following written on it: ``WDAC 280-32'' and ``99-004071-02'' and
- ``A2 12 APR 91''.
-
- My computer is put together from generic components in a standard
- desktop case. There are no ventilation holes except for the fan in
- the power supply, and I've run it with the case off and noticed that
- there is very little air being moved inside the case by that fan.
-
- My questions: If I get a larger case, say a full-tower, and move
- everything in there, is my problem likely to go away? Has anyone had
- a similar experience? Or is whatever is overheating likely to just
- get worse and need to be replaced? Or is it not even overheating, but
- something else, say static buildup?
-
- Any suggestions are welcome. Since I don't keep up with this group,
- please reply by e-mail to me (cwilson@cs.stanford.edu) and I'll post a
- summary of responses.
-
- Thanks in advance.
