My desktop computer's power supplies (three thus far) keep overheating and then fail permanently -- but only when they are plugged in through a power strip (i.e., everything is perfectly fine when the computer is plugged directly into a wall outlet). [more inside]

For about a year now, I have been having major problems with my home built PC. In the middle of 3D games (of any kind really), it will freeze for at least 10 seconds, sometimes more. Sometimes it will give me back control, sometimes it will reboot. More recently, it will blue screen (referring to nv4_disp) if it does not give me back control. During that freeze time, the sound will continue for a few seconds and then repeat like a skipping CD for a few seconds. [more inside]

Electronics filter: What can I do to make a 24v PSU turn into a 18-19v PSU? It's 0.5A power supply which as far as I can tell is important to know when using, say a resistor to lower voltage. But how resistant should the resistor be? I've found information on how to tell a resistor's value, but not how it will actually effect a line's voltage or how to calculate it. Are there any good sites with this information? Also what will happen to the amount of amps the PSU supplies when I do change it to 18/19v?? Also, what can be done to increase the amperage of a power supply? What inside the circutry is actually dictating the amperage?
