Two desktop PC burn-ups : household circuit problem vs unrelated (?)
Posted on 2009-12-29
First, a five year old or so Dell desktop. Was running fairly reliably on Windows XP - did have a blue screen of death or two per week though. But clearly was physically distressed, i.e. fan runninng furiously , clearly too hot. During a night, while I think was in sleep mode (but not certain of that) died as an entire circuit in my condo tripped, and the old cheap surge protector it was plugged into just about literally burned up (well, at least smelled like burned plastic/wire).
So, replace it with new Dell Inspiron 537S windows7. Running fine a couple weeks, then, while sleeping, or just idling (not so sure if it was in sleep mode or not) - it failed. Power supply gone. this time was plugged into a pretty decent new surge protector (which i think had "tripped" in that printer also plugged into it was shut down - but came back up undamaged.
So, question is, just how rare, or not rare do those of knowledge in such matters suppose it is for the power supply unit on a new Dell desktop PC to primarily fail? Or should I suspect there is some sort of bad incoming power supply issue?
