-First of all i want you to test and exhaust all software troubles before you move on hardware testing failures. Testing your hardware can be real pain if you don't know how it manifest itself and where to look at first place. I will show you how can you determine which piece of hardware causes you errors.
-So here we go one by one:
-Hard drive failure (HDD)
All errors which include moving, copying, reading, deleting or OS is unable to boot are main HDD problems. Also if your computer start to loop in circles can point you at HDD failure as well. First of all you need to use software to test your hard drive because some of this errors can be caused by another piece of hardware so you need to eliminate hard drive at first place. Use any of these software: HDD health, Test disk, Scandisk etc.
I personaly encountered one weird situation where HDD was bad, it boot slow and can only acces bios after 10 minutes and when in bios every move have a delay of few seconds. I replaced HDD and my problem was gone. At first i tought it was bios failure so i tried changing cmos baterry and flash bios which didn't gave me any results in process. I replaced HDD followed with new OS and everything worked like a charm.
-Memory failure (RAM)
Here is a list of errors you can get with bad memory chips: random reboots, pc does not boot at all, installation failures, blank screen, fatal (errors, exceptions and messages). If you suspect that your memory is damaged by any means you should check are they stay correctly in RAM slot and if there are more then one you should pull out one by one and eliminate damaged RAM. Also in some cases you can encounter our old friend called "Blue screen of death".
-Motherboard and CPU failure
This is worst scenario you can get in computer world and in most cases it ends up with changing completly your motherboard. There is numerous number of errors you can get when this issue happens and i will count few of them: pc does not boot, loophole, beeping sound, blue screen, several error messages after sucessefull boot and so on. You can use some software to test your motherboard but that's only case if you succede to boot your OS. Hot CPU tester is best tool to do such research.
My personal advice (use only if you are really sure all other options fails because this can cause irreversible damage) is direct heating of motherboard bridges (use hair dryer). Direct your heat source to GPU for about 60 seconds in circular motion and avoid by any means heating plastic parts or RAM slots! Of course you need to remove memory modules first and motherboard must be pulled out of computer. Again i warning you do this only if you think this is your last option and your motherboard doesn't have guarantee list for repair.
-Power supply failure
Here we have few situations you need to consider before you diagnose power supply failure. Power supply can be damaged by higher force (thunder and other high voltage strikes). Best thing you can do is to change your power source and keep going. Keep in mind that all other components of your computer are conected to your power source and they can also be damaged if you try to do some kind of tests on it. It's best that you only change power source supply to prevent more damge to your pc including the motherboard (check post above) which is worst scenario that could happen. There is no such software to test your power source integrity but if it still works you can use program who can monitor the voltage and power supplies to the fans. If you are not experienced with such hardware problems leave it to experts and they will do it for u.
Second problem can occur when you buying new complete pc configuration. As you already know every component of your pc use some power in order to work properly and here is great site where you can summerize your power supply usage for each of the components. If your power supply is not strong enough to supply all the components equally it will reboot as soon as you turn it on or it will not start at all, so it's very important that you calculate perfectly.
-CD-ROM and DVD drive failure
Before we begin with testing you need to make sure multiple disks nit working in the drive and by multiple i mean CD or DVD of the same kind. If DVD works fine and CD causing you problems then your drive is ok and problem is in the disk itself.
Your disk drive is damaged if you see errors like this: CD or DVD reading error, can't play any media files (audio, video etc), error when installing something from disks etc.
There is programs made for testing such problems and also there is CD or DVD cleaner if drive lens is dirty. CDRoller can be helpfull and also you can recover some lost files on damaged disk. And CDCheck is also nice software where you can recover lost files, and it's known for it's stability, ease of use and good support as well.
