Oh my gosh! I see dead monitors! Check these things before you panic.
The first thing to you need to know is whether you have power available to your PC. Are the LED lights on the system case lit and is the power supply fan blowing?
Is there power from your main socket wall? Plug another appliance into it. If it turns on, then you have power there.
Are you using surge protector? Try bypassing this. Try to plug it in the main.
Check on the PC’s power cable.
Most PCs have an On/Off switch at the back of the case. Make sure it is turned on.
All of these steps are to check for Power within your PC sysytem. If somehow these doesnt work, try checking on a certain Windows application called Advanced Power Management or APM. Try to research and tweak a bit. Maybe its because of a nisconfigured setting all along.
If you regularly use the internet and other Web related stuff, you must be cautious of computer hackers all the time. These people are always keeping an eye on your activities and looking out for ways on how you can access your financial and personal details, or unleash a spyware, worm, or virus to destroy the functionality of your personal computer.
Because of all these things, you need to have a good firewall protection for your computer. You should decide on what kind of firewall protection you will choose depending on your computer needs. You can either install a software firewall or a hardware firewall in the form of a Cable/DSL router.
Another cause of a slow computer start-up is the computer’s temporary internet files. If you clean this out on a regular basis, it can speed up your computer.
Check also your computer memory. If you do not have enough of it, this might slow down your computer start-up. This will generally manifest if you installed a new program into the computer and when the program is running, the performance of your PC will suffer. What you can do is upgrade your RAM or computer memory for better performance and faster speed.
Presence of a virus or falling hard drive are serious causes of slow start-ups of computers. Therefore, you should scan for viruses regularly and back up your files.
If you’ve messed up your PC and are tired of trying to figure out just what it is exactly you have done, you have an option called System Restore to get it back in shape without really doing any other troubleshooting steps.
You can liken system to a magic wand that you can wave to have your decrepit and cluttered home transformed back to the sparkly clean beautiful house you once had when it was still new. The only difference is that it will restore your computer to its previous settings as well as any other files you have backed up for that specific purpose. Of course, the actual restoration process takes longer than a wand wave.
As a user you have the option of creating a new restore point manually, or just restore your system to its original configuration. Note though that you can’t count on System Restore in case of a hard drive failure.

Heat is one of the computer’s worst enemies. A number of parts inside a computer generate heat, the most crucial of which is the processor. Computer processors generate so much heat that it needs constant cooling in order to function properly. Inefficient cooling will make the processor get so hot that it will start to malfunction. With enough heat it can actually damage the processor itself and burn right through the motherboard.
You should always be aware of the heat issues inside your computer case. Check that there is enough air circulating within the computer case to prevent any hardware failures.
Big name brands like Apple sell refurbished computers at a very reasonable price. This is a big draw to customers who would like to replace their old computers for newer models but cannot afford them at full price. If you look at it from the financial standpoint, refurbished computers are definitely worth it. But are they really just as good as brand new ones?
The truth is that refurbished computers are labelled as such for varied reasons. One of the reasons that computers are “sent back to the factory” is because of cosmetic defects. If you get a computer that was refurbished with only cosmetic defects being the original problem, then you can bet that you’re getting a great deal since the issue will definitely affect your computer’s performance.
If the original problem is due to something serious like CPU failure, then it is understandable to be more wary. However, remember that the problematic part has been replaced. The only real problem is that refurbished computers usually have shorter warranties. Still, if you have a limited budget, they are indeed worth looking into.

You are browsing the net and you get tired so you take a break and return to a computer with no display, what do you do? First of all, don�t panic and see if the CPU is still functioning with blinking lights or the power LED (the green thingy that is always on when you use your PC). If it is blinking, the PC has turned itself off going into sleep mode, look for the wake-up key on the keyboard and press, you�re back in business. If it still fails, sorry but you�ll have to turn off the CPU (computer actually) by pressing the Power Button until the power led turns off and the fan stops humming. Disconnect all cables and connectors from the CPU and open the casing making sure you touch the case before doing anything else (this discharges static electricity which could fry expensive microelectronics like your motherboard, memory module, CPU, etc).
If this is your first time, get hold of a can of compressed air specifically developed for cleaning computers and not from your garage compressor. Canned air is moisture free to avoid contaminating the electronics. Hold the Power supply for a few minutes while you take a look inside to admire the parts (this discharges any static electricity from you) Check all vents for the internal fans along with the one for the power supply. If they are dirty try to blow air through them to remove all dust and debris from all visible parts. If the said computer is visually dusty, you might want to do this outside the house. Also pay close attention to the CPU and blow air onto the fan and heat sink. Once you are satisfied and all visible dust and fido hairs are gone, you can reverse the process and take the camera shots to re-connect all the cables and chords that you took out and boot up. A clean computer runs cooler and more efficiently, besides too much dust on any of the internal components can lead to parts failure due to the insulating properties of dust.
To junk some of your unused files and clean the Windows registry, you have to grab yourself a cleaner software program. Once you have this program, just close all of your applications and open the software. Click on “Clean Now” and you will see that the program will remove almost all of the temporary programs or files in your machine, which are normally the cause of many common problems. Then you will see the result on the screen on how much files were removed.
Then, click on the “Repair Errors” button. Click “Scan for Errors,” and when the process is complete, just click “Fix Errors” and it’s all complete. Restart the machine and if the problem is not yet fixed, you already have a more serious problem which needs a technician to troubleshoot it for you.
Moving on, everything from CF cards to flash memory cards, from batteries to USB peripherals can encounter this problem. I remember that the same thing happened to me with my PlayStation Portable unit. When I inserted the Memory Stick Duo, it was not recognized. I was sweating profusely and I restarted the unit and turned it on again, much to my shock that it seems it was empty. All my photos, saved games, or movies seemed lost. It was almost a year since i cleaned my memory card so i proceeded to clean the contacts using the eraser on my pencil and inserted it back to my PSP and Voila! The Memory Stick was alive again.
