Once again, thank you all for your advice! I've got XP installed and updated, drivers installed, and all of the files back on the computer. I downloaded the drivers from the eMachines web site. All but the ethernet driver, that is. For some reason, eMachines has chosen to not provide it over the web. Perhaps they assume that if you're connected to the internet, you already have it installed. Or perhaps there are different ethernet cards installed on different motherboards. <soapbox> Both of these are conjecture, but I can't say either are satisfactory. If a company is going to provide support to their customers, they should provide all the resources that make that support complete. Inadequate/generic documentation and missing drivers are not acceptable. </soapbox> So, I looked for the motherboard model number and went to the intel download site to get the ethernet driver for their d845gvsr board. That happened to be the board model in my friend's T3828, but they could be using other boards for different batches, right? I looked at the capacitors, and none of them seemed to be leaking or expanded. I downloaded HWMonitor from www.cpuid.com. All the voltages and temperatures seem to be in normal range (CPU @ 35 deg C, HD @ 38 deg C) except for the +12V post, which fluctuates from 11.68V-11.80V. Is this an acceptable way to see if the power supply is doing its job? And, is this an acceptable range for the +12V post? Drew
