The case, this doesn't require much troubleshooting nor does it go bad that often. The most common problems is just its ugly and maybe out of style. One component of the case that will and does go bad is the power supply. So what can you do when it goes bad? Replace it, or buy a new case with a new power supply installed.

-Common Problems, this can confuse you if the power supply does go bad. One of the most common things to happen is just strange errors with your computer. You may have software glitches, hardware, and any other act's of Satan. So how can you evaluate what the problem is and narrow it down to a power problem? This is done mostly by trial and error. Checking something as simple as a power problem can save you money down the road simply by not having to replace hardware to see if the problem is fixed. Never underestimate the value of your power supply! Here are some common symptoms of power supply problems.
-Flickering and Dimming Lights
-Keyboard or System lock-ups (Don't Blame Windows)
-Random Shutdowns and Reboots
-Again, don't underestimate the power supply. Who is to say its not the Operating System that has caused you failures? Check some things out before spending money on parts. If you know and have identified this as a problem think about a UPS (Uninterruptible Power Supplies). This can also solve under powerment. Also think about how many devices are hooked up to one circuit in your system. If you have some power hogs taking up the juice you need this could be a problem. For the most part power problems can be caught if it just flickering or dimming lights. We all know this one, but random shut downs can really throw you for a loop.
-Now what are some very common signs of the power supply is going to fail on you? This is pretty much common sense and you can miss it.
-Fan Noise has become excessive
-No Fan Noise
-The Power Supply Chassis is extremely hot
-This power supply being extremely hot to the touch is not a good sign. It wont be long before you have some potential problems. I would start to worry about this one. You don't want a fire hazard on your hands anytime soon.
-Another thing, do not attempt to mess with the insides of power supply. This can kill you and does not need repair! Replace it! Even if the fan is bad simply replace the whole supply. They are cheap enough so don't put yourself through a bunch of heartache.
-In these modern times power supplies aren't something you ignore. I've had a few bad experiences with power supplies blowing on me and taking out my motherboard with it. With new graphics cards requiring a power source from the power supply I would recommend a 480w minimum.
-Do not buy a cheap unbranded power supply, you will only regret it later on. Some quality well know manufactures of power supplies are as follows: Antec, Tagen, Enermax, OCZ.
