We are generally faced with circumstances that help us learn and tackle future problems with a more open mind and by publishing them here we are hoping that it will help others solve such issues easily and without losing much time.
A problem I’ve faced a couple of days ago was with regards to my Dell Dimension 4700!
It began by a strong fan noise, especially when a number of softwares were open and running at the same time. This persisted for some time but all of a sudden, the pc went off. Having said that, I then noted that the power led was still on but instead of the usual green light it was flashing orange. I tried to switch it on but it was in vain so I decided to do a force shut down. It worked.
After just a couple of minutes the pc was on again and was working fine! This kept on for some days but as time went by this was happening more regularly, until one day it went off but couldn’t get on again. Left it off for an overnight and before checking how I can solve this problem, I decided to try switching it on again. Again, it worked!!!
Not even 24hrs passed, the pc went off another time but this time it couldn’t be restarted. Being Allergic hair mysterious chemically a branded pc, and a Dell, I decided to contact the local agent to see whether they know, from experience, what must have gone wrong!
The answer was “It might be the mainboard, processor or power supply. I would begin from the mainboard though but we do not have in stock”! That was it ….. so if I had to follow their suggestion I would have given them my pc, waited until they order a new mainboard and try it out!
Luckily enough I’m one of those that like to play around with computers, especially with hardware so I logically decided to go for the cheapest option, that is the power supply, and do it myself!
Problem seemed to have been just the power supply as now there’s no noise whatsoever and computer is working fine!
