WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.
Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards
Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

Remove the memory modules from their slots.
Take the opportunity to clean the slots on the motherboards and the memory module connectors.
Use compressed air to blow dust away and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.
Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r
Allow the pins to dry.
They will air dry in a matter of minutes.
If reseating the memory did not resolve the issue try swapping the location of the memory.
If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.
Check the memory module and memory slot contacts.
They are either copper tin or gold.
The colour will tell you which they are.
Mixing tin and gold can result in corrosion that prevents proper contact.
Look for any sign of physical damage to the memory module, memory slots or the motherboard.
Reseat the memory modules.
You should hear an audible click when they are in place.
Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard.
The hardware that you are trying to access is damaged or failing.
The device drivers for the hardware are faulty or incompatible.
Could be a problem with the Hard Drive or the Hard drives PCB
http://www.onepcbsolution.com/
There is a connection problem such as a bad cable
for internal hard drives
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a
secure dust free connections and are not faulty or just replace them they could be faulty if its a flat 40pin ide
this will be the first to fail
Make sure all leads that are attached to your drives dvd\cd and floppy (If Applicable) have secure connections and are not faulty.
or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error Hope this helps.
click start control panel administration tools computer management device manager scroll to sound video and game controllers you might see a yellow question / exclamation? ! mark or a red X Right click to reinstall drivers
if your computer came with a motherboard disk the drivers could be on it
or you might download slimdrivers
rather doing a driver hunt
http://download.cnet.com/slimdrivers-free/3000-18513_4-75279940.html
note: it will find all of your outdated drivers
this is a free driver solutions
which will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point click no to both of these then continue updating each driver free then restart once all of the drivers have been updated
it might take some time being freehope this helps
Refer to your motherboard manual, since the motherboard is the beeping device. These beeps are like Morse code, and each "beep code" is explained in the manual. Common beep codes include not having a monitor or keyboard properly connected; not having a CPU fan connected, or not attaching internal power cables to the video card. This black-screen-and-beeping issue is most common with newly-assembled computers.
Check external cables to make sure they're properly connected. The most important external connections to check are the monitor's signal cable and the keyboard. If your monitor cable looks damaged or kinked, try replacing it with a spare. If your keyboard's cable looks frayed, try a spare keyboard.
Also, a PS/2 keyboard plug (round, with holes in it, about the diameter of a finger) is often color-coded purple. If you have plugged it into the green port in the back of the computer (for PS/2 mice) switch it to the other one. If there is no color coding, the proper port should have a small, embossed icon of a keyboard on the back of the computer. If it does not, refer to your motherboard manual for the correct port. If all else fails, try a spare keyboard, preferably USB (Universal Serial Bus), which can be plugged into any USB port on the back of the computer.
Check for additional motherboard power connections. Yours may require multiple cables attached from the power supply. There is the standard wide plug, which you know is connected properly because your motherboard is beeping. However, there may also be an additional, four-pin cable that connects elsewhere on the motherboard. Check the board's manual to make sure it has all the power connections it needs.
Check your internal cables. Make sure that the CPU fan is plugged into the motherboard header nearby. Without that, the CPU fan will not spin, and the motherboard may detect this lack of connection and produce a beep code. Your video card also may have one or two internal power plugs that need to be attached to the power supply's cables. These cables have unique ends on them, similar in shape to a USB plug. Refer to the case or video card documentation if need be. If those cables are not attached, your motherboard may refuse to boot the system.
Your video card may be faulty. If this is a new card, it may have arrived to you broken, in which case you will probably need to request an RMA (Return to Manufacturer Authorization) to receive a replacement. If this card was previously working for you in this system, you can contact its manufacturer yourself to receive a replacement, if the device is still under
