Just installed a new ACORP mobo with AMD 450mhz processor (see my post on 4/24 - "No POST,..."). Everything works fine for the first couple hours, and things begin to crash, including Word, the volume control, dial-up connection, norton utilities, (I'm running the Norton crashguard, which also crashed!), etc. If I reboot, sometimes I will get a crash of Spool32 and Msgr32 during initialization. Sometimes it just locks up entirely.
This is a generic tower PC with one fan for the case, and an internal fan for the PSU. The AMD processor has a fan with a heat sink. Could this processor be marginal, or are they just sensitive to heat? My next test was to run with the cover off.
