If your PC boot�s up but doesn�t load windows, then it might have been shut down without using the shutdown facility provided. To fix it, simply press F7 and select safe mode from the command line menu and follow all in-screen instructions. Some files or system drivers get damaged by such events so have the driver cd�s at hand. Once the check disk facility finishes, you should be able to gain access to your PC normally. If it still won�t load properly, try shutting down and re-starting for there might be some corrupted programs that need to be restored. Try getting the windows installation CD�s and re-install windows to restore all the damaged system files.

Well, this might not be a sound you would want to hear from your hard drive, for it might be in it’s death throes. The screeching sound may be the bearings that make the platters spin breaking down or they have been in use for so long they have worn out the hard metal coatings on the teeny tiny bearings. The first thing you do is to copy as much data that you can to another hard drive to prevent total disaster. Most drives will continue to function for sometime before total failure of the drive. You’ll be glad to know that they have become more reliable than ever but that does not mean totally.

First check the power chord and the cable that connects to the CPU. If these are firmly seated and there is still no display, the video card may be defective or the least needs to be re-seated. Pull out all the plugs and wires connected to the CPU and open it. Try to remember the place where the monitor is connected and you get the video card. Remove the said card by unscrewing it from the casing and removing or sliding any retention tabs that was supposed to prevent it from pulling loose. Pull it out while taking care not to remove any of the other wires that are in the CPU unit itself. Check for any visible damage such as burn marks or a smell that I assure you that you won�t soon forget. Any of those signs and get packing for you are getting a new one. If unsure of the type (there are several types of video cards), bring the one you pulled out as a basis. When at the store, try getting something either equal to or better than the one you have. When you get home, touch the CPU power supply to again discharge static and re-install the aid card. Remember to re-attach any cable or fan power supply you might have had to pull out to get access. Re-assemble the unit and boot up(you might have to install the drivers of the new card if you were unable to get the same type and brand).

Look for the video card and check if it hasn�t popped out of it�s slot (remember the monitor, the card to which it is connected to is the video card), if so re-seat and try booting up. If the video card is embedded (meaning it is part of the motherboard) it may have failed (sorry, replacement is the only option for this form of motherboard) or if you have a slot for third-party video cards you may purchase one and disable the one embedded within the system.
Note: It is normal for Video Cards to pop out of their slots (AGP or PCI) due to some manufacturers making them with teeny-tiny edges where the contacts are located that fail to seat firmly into the board. They tend to jump out by themselves especially if the PC is used heavily or there is a source of vibration nearby say in an office. The short edges, instead of being grabbed by the connector on the motherboard, sits just above the clamping part which acts as a spring hence the jumping part.

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.

Disconnect and isolate, if you suspect one of your computers has suffered a virus attack, immediately quarantine the computer by physically disconnecting it, as infected machines pose a danger to all other computers connected to the network.
If you suspect other computers may be infected, treat them like they are. It’s counter-productive to clean one machine while an infected computer is still connected to network.

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).
