1. Heat.

Test for this issue by removing the case cover. Better? Same?

2. BIOS versions.

My experience is to use the latest offered.

3. Software issues.

a. 3 Megabytes free except on Windows 3.11 is just not stable and it will be slow. BUT DO NOT merge the partitions on an unstable PC. A great way to lose it all.

b. Post the same post in the XP Forum to get input on software issues.

c. You didn't tell what you do to remove and keep off SPYWARE. Do tell.
