I have bought a new(er) Dell Studio XPS 8100 and since retired my Dimension 8400. Despite a fresh system, sooner or later, problems will arise, often ones that are difficult to troubleshoot. That goes with any computer system, anyway.
I have no formal training in information technology, yet I try to troubleshoot computer problems myself. With that arises a somewhat crude scientific investigation, testing one component at a time until the problem disappears. So, what is the problem this time?
The problem:
Apparently randomly, the display's screen would go blank. Unlike last time, the problem would correct (temporarily) by pulling the plug and rebooting.
