Question about E-Machines T2042 CELERON 2 GHz 128 MB 40 GB HDD Dsktop Computer System PC Desktop
Remove the cover to look at the power supply fan while it is powered on ( if needed). The fan should be spinning at a steady rate. If you observe fluctuations in the rotation, these are early indications of a malfunctioning power supply unit. As for the knocking sound, can you hear it better or determine its source if the cover is removed? It could be the fan hitting the side of the power supply or wiring. The good news is that if it IS the power supply, they are relatively inexpensive and easy to replace. Your sister may not be out of luck!
But if the light is blinking- and orange - this is definite indicator that the power supply is going. Still a good idea to replace the p/s unit and let her use it. With RAM being as cheap as it is, I'd also recommend bumping it up to 512 minimum if not a 1 GB.
