Recently, I started to get a large noise from my PC when switched on. After some time, it disappears. I discovered that the issue is with the Power Supply Unit. Does this mean I have a failing PSU? Will it harm the PC if I didn't replace it immediately?

Several years ago I bought a new computer casing which is very weird. Its small and compact. Normally, we have the PSU in the top. But in here, the PSU is on the bottom and right below the hard drive. Recently, two of my hard drives started to show problems. Read errors and bad sectors. Can it be the PSU and the design of the casing?

Here's an image of the PSU and the hard drive :

  • Is it a jet enginish whosh or a "ladaladalada" like something is loose inside? – Journeyman Geek Nov 2 '12 at 9:30

It is so hard to answer but, if you computer is old, then it's a chance it is failing (and if you replace one part of all could be the bigger question).

Can the PSU cause problems - well, yes, if it spikes. Is this going to happen - I can't tell. I've had many PC's and looked after many PC's in jobs and have experienced it once (during a powercut).
