Steps
1. First of all you have to determine the cause. Constantly restart the PC in order to confirm that it won’t boot. Next you should try the PC on it’s side to eliminate a connection error. This could either be a burnt out or worn contact or simply a connection which has come loose. After this you can start the process of fixing the problem
2. There are a couple of problems that will cause a computer not to boot these are: Corrupted BIOS, Corrupted Start up files, corrupted hard drive (containing startup files) or a broken motherboard.
3. If absolutely nothing happens when you press the power switch:
- Check that it is plugged in and switched on both at the wall and at the back of the base unit, check that the wall socket has power.
- Check the power supply by removing it and testing it in another machine, if it works fine in another machine, check your power switch connections.
- Check the fuse in the power supply; typically if it is blown, is is blackened, or the little thread inside is interrrupted, when held against a light.
- If the connections are fine it is likely that your motherboard has died.
4. Check for a faulty motherboard.
- Remove every connection and component from your motherboard except for the power, front panel, CPU assembly, RAM and graphics card, switch it on.
- If you have more than one stick of RAM test them one at a time.
- If this works then reconnect your other devices (Switch it off first!) one by one until you find out which one is causing the problem.
- If your hear sounds of the disk starting, but nothing ever happens on the screen, the BIOS might be corrupted. That can happen when you try to flash it with a newer version, or if an ugly virus flashes it with garbage. If so, the BIOS needs to be reloaded correctly, or the chip replaced. Note: Not all computers have their BIOS in a flashable EPROM, so this might or might not apply.
- If the board makes a sequence of loud beeps, there is a hardware error in one of the basic components. Two beeps mean ‘no monitor found’, four beeps ‘no memory found’, etc. (that list is not for sure). It is the BIOS reporting that it misses an elementary part to continue. Find out which part is broken (or really missing), and replace it.
5. Replace the Boot Sector.
- Place windows installer disc into drive.
- When prompted, press R to start the recovery console.
- When asked which system you want to log into press 1, then enter.
- You should now have a C:\WINDOWS\ prompt, type fixboot and press enter.
- Type FIXMBR and press enter (that means ‘FIX the Master Boot Record’ = FIXMBR).
- Reboot the machine, if it works, you are done.
6. Check your BIOS settings
- To enter the BIOS menu you must tap a certain key as soon as you switch on the PC, this is usually DEL or F2 but it will say on screen, e.g. ‘PRESS DEL FOR SETUP’
- All BIOS menus differ, what you are looking for is a bit called Primary Master, which should have somenumbers after it, if it does, then your drive is not at fault, move on.
- If Primary Master has no information after it your hard drive is not being detected, if you are able, change the setting next to Primary Master so that it says ‘Auto’.
- Save and exit the BIOS, if your computer boots, stop here.
- If your hard drive is not detected this time you will need to open up the case and check the connections. http://www.wikihow.com/Hook-up-a-Hard-Drive
7. Check for a faulty hard drive
- Remove your hard drive and put it in another PC if possible.
- If it does not work in another PC then it is dead, buy a new one.
- If it does work in another PC, try using different cables.
- If different cables make no difference your motherboard may be faulty.

Tips
• Make sure to buy your components from a reputable dealer, check reviews online and in literature.
• I you have to take the cover off you might as well clean it up a bit, blast all the dust out with a can of compressed air.
• If the PC has stopped working after a recent update (RAM, Hard drive..) remove this and see the problem still exists.
• Remember that Windows XP can only take a maximum of 4 GB of RAM
• If your PC problem is BIOS related, it should boot when the BIOS disc is inserted
• Always turn off and unplug the PC before touching, adding or removing parts within the pc
• Wear an anti-static wrist band or ground yourself by touching the case while the system is plugged in.
• Make sure you do not have excess moisture on your hands, if you get sweaty palms then wear anti-static gloves, e.g. nitrile gloves
• As with any device that plugs into wall current, if during testing you smell ozone or burnt plastic, or hear a “popping” or arcing noise, unplug the device immediatly. Unless you know how to work with electicity safely, an internal short is best repaired by professionals.

Prediction is expressed by McAfee Labs. In addition to social networking sites, users Adobe Flash System and any risk of becoming a hacker target.

Director of Security Research and Communication McAfee Labs David Marcus says, the perpetrators of crime is likely to attack to Facebook and Twitter and other social networking services.

Not only Koobface viruses, virus attacks through Facebook applications will increase.

“When you click ‘yes’ to access an application, you provide access to applications that are clickable to see all the data your Facebook account,” Marcus said as quoted by CNet, Wednesday (30/12/2009).

Meanwhile, vulnerability against hackers Twitter more often caused by services such as peringkas bit.ly URL and tinyurl.com.

“There is nothing wrong with the Twitter service. But when you click a URL peringkas, you do not know what the target site until you actually had kliknya. Even today, there is no peringkas The URL to provide security for the targeted sites,” Marcus said.

Not only social networking site, Operating System (OS) Google Chrome will create new land for the creators of the virus to infect computer users. Thus, most likely Google Chrome will accompany the Microsoft OS that has been vulnerable to attack claimed. McAfee Labs also reminded that the appearance of a Trojan virus is more intelligent and dangerous
