Figure out Why a Computer Won't Boot

How to Figure out Why a Computer Won't Boot(2)

Steps

5.Try to start the machine up again. If the computer didn't start up in the first place, check the power switch lead. These little buggers can frequently get unknowingly moved to adjacent pins if you're not careful. If your power switch lead is in the exact right place, check your ATX 12v auxiliary connector. It is a common mistake for people to leave this unplugged.

6.If nothing is working, take the little battery out of the motherboard (should be near the southbridge) and wait 2 minutes for it to fully discharge. Remember, you must have the power cord unplugged to do this. (You should never have cords attached to the back when you're working on a computer.) If you know which jumper on your motherboard is the clear CMOS jumper, you can just move that to the other two pins and wait 5-10 seconds to clear your CMOS. If absolutely nothing works, try taking all of the parts out and putting them back in. This shouldn't be just one by one. Take all of them out, lay them on a table, and put them back in, making sure to connect all necessary wires. Also, make sure you're grounded by simply touching the power supply every 5 minutes or so.

7.If you have a hardware problem and you aren't comfortable working on the inside of computers, take it to a local computer repair shop and describe your problem. The better you describe what's happening on your end, the easier it makes their job on their end, and it'll be cheaper because they won't have to screw around with it as much. If you're a brave soul, and would like to try to fix it yourself, go to the next step.

8.Open up the computer. You should be able to do this by unscrewing the screws on the back. DO NOT unscrew any screws that are near a fan. Only ones on the very outer rim of the back.

9.Do not touch any components of the computer except for the power supply, which you should touch every 5 minutes to keep yourself grounded. This will keep you from frying any of the expensive components in there. One electrostatic shock can bring your system down for good. The power supply is located in the upper left hand corner, and it should have a lot of thick wires coming out of one hole in it.
