This is my son-in-law's pc so this is his memory of it's operation.
In the past, pc started fine for years then it started to come-up slowly. After a while it took so long to start that once it come-up it was not turned off for days. After a while of this operation (week?) it would not start at all. I took it home and started my analysis.
Everything was full of dust. Fans, openings and inside. I cleaned it out but it still would not start. I reasoned that the dust slowed down air flow and something overheated.
I removed the psu and l pugged it in a Power Supply Tester I had but the only LED that came on was the +5VSB light.
The problem is either the psu, cpu or the mother board (MB). There were some capacitors near the cpu that were suspicious. The tops were a bit corroded (leakage?). All the many capacitors on the MB were clean.
I ordered a used psu for $39.00 which is not a lot. If it's the MB or cpu it probably will not be worth the cost.
Do you think dust can cause failures?
