  Absolutely.  Plus, IMHO, 2 other major players in PC instability.
Fully half the constant-crash problems I see on home-built or local-shop
PCs are due to improper cooling and/or a cheap low-Watt PSU.
  I worked on an E-Machine a couple of weeks ago that was delivered with
a K6/2 450 CPU and a $10 HS/fan combo, with no thermal paste at all.  A
7200rpm ATA100 drive, CD-RW, Jazz drive, and 90W PSU.  The owner told
me "It crashes a lot."  Duh....
  I run at least a 300W PSU and lots o' fans on anything I want stable.
It's louder, more expensive, and probably excessive.  It gives me warm &
fuzzies.
