In this article we'll go over some of the most common hardware problems, at least in my experience, and the best way to go about getting them fixed.

The Computer Won't Turn On This is a common problem with some interesting solutions. Often overlooked, some solutions can be the most simple. There are two main symptoms to take into account before going too far into the repair: Is it the monitor or the computer that isn't turning on?

It would be a shame to start opening up a computer system to test for bad parts if it's the monitor that's the problem. If the tower turns on, and the monitor does not, the first step should be the most obvious, but is often overlooked -- check if it's plugged in.

I can't tell you how many times I have come across a "frozen computer" that was simply a case of an unplugged mouse or keyboard. Always take a second to try the most obvious things first.

It could save you a lot of time. Assuming everything is plugged in and properly seated, try plugging in another monitor to see if that one works; don't forget to try different power outlets as well, it isn't uncommon to blow a fuse, especially with more power hungry systems.

If the second monitor works, you are likely dealing with a bad monitor. Unfortunately, in this case, there isn't much you can do. Most of the time, it ends up cheaper to replace the monitor altogether than to try to get it repaired. If the monitor seems to work, but the tower doesn't turn on, the first thing you'll want to check is the power supply. A good test of this is to see if any lights turn on in the front or back of the tower.

If they don't, the power supply unit PSU may be at fault. Some PSUs have a dedicated power switch, if it does, ensure that it is switched on. Next you can open up your tower and look at the motherboard, most motherboards have a small LED light built in to show if power is running to the motherboard. If you can't find any evidence that power is properly running to the motherboard, you can either try using a PSU tester, or a replacement PSU.

It is not uncommon for PSUs to go out, so this is most likely the problem and a replacement is in order. Never try to open a PSU and try to repair it yourself, this is extremely dangerous; with replacement PSUs being so inexpensive, it really isn't worth the risk.

If you are able to see lights turn on and power is obviously flowing to the computer system and monitor, there may be a component issue.
