Dell SmartStep 250N Upgrade

I installed Windows 7 on the Dell SmartStep 250N and although it runs, it's slow and could use some help.

Current specs:

• Intel Pentium 4 2.40 GHz, 512 K Cache, 400 MHz FSB
• 40 GB HDD
• 1 GB RAM (max)

Dell SmartStep 250N Overheat Solution

I have an old Dell SmartStep 250N and let me tell you it's been hell trying to figure out a solution to the overheating problem.

Symptoms:
Computer runs for a period of time, but as soon as the CPU usage spikes and the CPU fan kicks in the computer automatically shuts down.  Things like playing mp3's and video files for a sustained amount of time causes the shutdowns.
