Answer 1

To begin your troubleshooting, open the PC's case and remove the video card, the sound card, any network interface card or modem, and disconnect the hard drive and the DVD drive - the cables that connect them to the motherboard and the cables that connect them to the power supply. Make a note of where the cables connect to the motherboard so that you can replace them. If you can't remember where the cables connect, you'll have to consult the motherboard's illustrated manual. If any one of those components fail, it shorts out the motherboard and prevents it from receiving power. If the PC is connected to the web via a modem or modem and network interface card, they can be hit by a lightening strike.

If the PC starts up properly, press the key that enters the BIOS (usually the Del key). Now you know that one of the components you removed is the cause of the problem, and it's a matter of installing alternatives until you find out which one is responsible.

If the PC still displays the same symptoms, you can even remove the DIMM memory modules.

If doing that doesn't allow the PC to start up, you can try resetting the CMOS memory that contains the BIOS setup information. The motherboard's manual will show the position of the reset jumper pins on the motherboard. If you don't have a copy, download one from the manufacturer's website. Usually there are three pins sticking up near the coin-shaped BIOS battery, with a jumper over two of them. Remove the jumper and place it over the pin that wasn't covered and the one next to it. Click here! to find out how to do that on this site. You don't have to restart the PC, merely changing the jumper setting resets the BIOS, because the pins maintain power to the CMOS chip and when you remove the jumper and place it over the alternative setting, the information in the BIOS is removed. The CMOS chip is hard-coded with the default BIOS settings, which are then transferred automatically into the chip's battery-powered memory. You must then replace the jumper over the pins it covered originally. If there is no jumper there, remove the BIOS battery for five minutes and replace it. Click here! to find out how to do that on this site.

If the problem still remains unresolved after all of that troubleshooting, just in case the power-on switch has failed, remove the cable that connects it to the motherboard and connect the reset switch's connector to the power-on pins on the motherboard, and press the reset switch on the case. On all ATX PC cases, the power-on switch just has to be shorted momentarily to start the PC. If the PC has no reset switch, you can briefly short the two power-on switch pins with the end of a screwdriver to make the PC start up. You won't get a shock because a screwdriver's handle is insulated. If you need illustrated information, the motherboard's manual will have a diagram that shows where the power-on, reset, and LED pins are located.

If the problem still remains unresolved, it must have something to do with the motherboard, power supply, or the processor. The only way to find out which of them is responsible is to replace each of them in turn. But, since you have no alternative components, you should take the PC to a reputable computer shop for testing, or consider upgrading your PC by buying a new motherboard, power supply, processor, and RAM. If you buy one of the latest AMD Athlon 64 or Intel Pentium 4 processors, make sure that you buy the correct type of motherboard for it, a quality 400W to 450W power supply that has the correct 20-pin or 24-pin power connector, and quality brand-name RAM. Download the motherboard's manual to find out which kind of power connector is used to connect it to the power supply. Most new motherboards are connected to the power supply by a 24-pin power connector.

Answer 2

You should remove and reinstall the cpu, vid card and memory and try that. Also the plugs on the back of the computer. If that doesn't help, unplug not the power suppl but all the other plugs from the board. Not the sw connection. Then try it again.

Be sure the plugs for the HD, CD and Floppy are correct and tight.

There's so many small things that could go wrong, just try them all one at a time. Take a break for a while to get a new perspective and not too frustrated!! We've all been there.

Answer 3

You sure got some wild answers from 'experts' that doesn't know anything except the names of some computer components! You don't give enough details for an answer that means anything so I suggest you present the problem to someone in person that can ask details of your installation and answer step by step. My Staples store has a repair service as well as Circuit City. Check your local area for repair shops. This should not be an expensive 'repair' if the new motherboard is good and it is only a minor wiring / hookup problem.
Good luck.

Answer 4

Oh man...the dreaded silence after rebuilding your precious computer. The sound, or actually the lack there of drives me crazy! I've heard it my fair share of times. And to be honest, it can mean 2 things. 1: Something isn't hooked in right, PSU isn't on, power strip needs to be reset, etc etc. OR (And more the common answer unfortunately)2: You had some hardware that was DOA. And if you aren't getting anything from your computer when you turn it on, the most likely culprit would be that new mobo of yours. Other possibilites are the PSU is dead, OR the proc is toasted. Please don't kill the bearer of bad news! Good luck! I actually hope I'm wrong!

Answer 5

dissemble the motherboard from the cabinet and keep outside and check the display . may be u can have some result

Answer 6

does it "beep". if it doesn't something isn't plugged in right. if it does it could just be your video card isn't installed or that your monitor isn't synching up with the pc, try turning the monitor off manually and then boot the pc then turn the monitor on while its booting.
no "beeps"= no post
no post=not working at all
start over

Answer 7

If your computer is not working properly when it is switched on, it could be a problem with device drivers, hardware or software.

Answer 8

A good tool I used to clean up and speed up my PC is CCleaner. You can download it for free here http://bitly.com/1sW2dva
I have been using it for years

Answer 9

Do you hear a "beep" sound?
if yes, I think you should check your memory (posibility problem) or you can release the memory module and swap to another slot

Answer 10

Please confirm whether the monitor is on and then check the smps connection and the status of lights on the CPU.
