Hello. I bought a CyberPowerPC Gamer Xtreme 1077 back in 2011, and it has recently started to run very loudly. I've given it several thorough cleanings, to no avail, and, by opening up the case and listening to each fan individually, I've come to the conclusion that the one that sounds like it's trying to achieve flight is the one in the Power Supply.
It's a rather inconsistent problem. Sometimes I'll get a string of noisy starts, other times I'll get two or three hours of work in before the fan starts running loudly, and I haven't figured out any rhyme or reason to the differences in noise level.
A quick, general, perusal of the internet suggests that I should either oil the fan of my Power Supply or, as I'm not a trained professional, replace it lest I kill myself/fry my PC tampering with the gods' gift of electricity, but which of those is my best approach is really my second question. I have virtually no experience on the hardware end. This is the first computer I've used that hasn't been A) a hopelessly lost cause like my Dad's decrepit computer or B) under the careful supervision of a dedicated, Batmanesque IT department, so I'll let that inform whether I should repair or replace the PSU.
The first question is just how do I get to the damn Power Supply? All the wires coming out of the PSU are threaded through a frame that's holding up the CPU and hard drive, so they sit between that and the access panel on the right of the machine (looking at it from the front) that I can't seem to open. When I unscrew the PSU and take off the other side of the case, I've got maybe about an inch or two of slack from those cables, which is barely enough room to look at the thing, much less take it out and replace it/perform any sort of maintenance on it.
So far, the PC has avoided any of the catastrophic failures that seem to have plagued other CyberPowerPC customers that I've been reading about while looking for help with this relatively minor issue, and the noisy fan has been my only trouble. I haven't yet found a pressing need to (or had the spare cash to) upgrade or replace any of the components, so everything is as it was in 2011. Specs presented below, if it helps.

I have had to replace a PSU before,,


              Is the PSU touching anything that could possibly make it vibrate or is it loosely secured (ie loose screws)?  A quick reminder, try to think of how  all the components went together in the first place and what sequence.take pictures and/or draw a diagram of all the connections the PSU is making including pin count and configuration... the most important is the 20 or 24 pin connection to the mobo. mine was deifinitely tricky to get the old one out and seat in the new one. you know when you need a new power supply when you get random shutdowns for no apparent reason and when you do boot back up, there isn't a BIOS message indicating a thermal event which would indicate an overheated CPU


                although a noisy PSU fan is pretty rare, there may be some sort of voltage draw from an exposed wire touching a ground source or something, wish i could tell you more about PSU voltage irregularities  but there are a few guys that know alot more about  that kind of thing that may read this and help .

Can you provide a clear photo of the whole system? What i can do is label where all of the cables from the power supply go.
