Trouble Shooting Your PC Problems
Your son/daughter needs to use the PC to research a project for school the next day. You hear an "Oh No!" from the den or wherever the computer is located. The PC won't boot up or won't turn on! You know nothing about PC's beyond checking your email. Does this sound familiar? If you are lucky you have a teen ager that is computer savvy or you know this friend that does. Would you like to be able to take care of it yourself and be a hero in this son/daughter's eyes? Perhaps we can get you started in that direction. I am compiling a series of articles that might help prepare you for this. It is not a matter of "IF" this will happen but one of when it will happen. Murphy's Law says it will happen when you can least afford for it to happen. I have been that person with the savvy in my family since PC's showed themselves in the early 1980's. If it can happen, it has happened to me.
Common PC Problems Facing the PC User
Computer problems may seem immensely complicated at first glance. But some are relatively easy to fix
. That doesn't mean they will be cheap if someone else does the job.
However, some jobs can be done by the average Joe or Jane
. On a scale of 1 to 10 (where 10 should only be performed by certified technicians who have no less than three electronic gadgets on their belt), replacing memory is usually about a 4. Installing a new hard drive is tougher (about 6 or 7), but still doable. Replacing a video card or internal modem is no more than a 2.
A word of caution: Static electricity can kill the circuitry inside your computer. Before you reach for anything inside that box, ground yourself by touching the metal computer frame. Do yourself a favor and purchase a wrist grounding strap. They can be found at Best Buy for around $5.
Here are four common PC problems you may be able to fix by yourself
:
You turn on the computer and nothing happens
.
It Won't Power Up
No lights, no beeps, no fan noise. What is the first thing you do? Be sure the darn thing is plugged in! Even if you're absolutely certain that it is connected, double check.
Assuming that it is plugged in, you probably have a bad power supply. This is a metal box located in the top and back of the computer. It is usually held in by four screws and the power cable connects to it. A fan blows air out the back.
A wiring harness exits the power supply inside the computer. Numerous power connectors are attached to the ends of the wires. These plug into drives, fans and possibly other gizmos. The harness also will have connectors to the motherboard. It doesn't matter which wire connects where, as long as the connector fits.
The computer comes on, but nothing appears on your monitor
.
In other words, Windows never shows up. You may have a monitor problem. Try using another known-good monitor on the computer and see if anything shows up on the screen. If the second monitor works, the first one is bad. Monitors are not worth repairing. Just buy a new one. Never open the back of a monitor to fix it. The capacitors inside monitors store electricity. You could be injured or even killed.
If the screen is dark, it could be a video card problem. First, find the video card. This is a circuit board that fits into a slot in the motherboard. The cable from the monitor connects to the VGA (video graphics adapter) port, which sticks out through the back of the computer. If the VGA port is part of the motherboard, the video is built-in. You can't fix that. Otherwise, it will be part of the video card.
Assuming you have a separate card, be sure it is firmly seated. The front end of the card can rise out of the slot inadvertently when the back end is screwed down to the computer frame.
If you have a computer that is working perfectly, turn it off and remove the video card. Put the card that works in the problem computer. If the system works, you need a new card. If you don't have an extra card to test your system, buy a cheap one. If it doesn't solve the problem, take it back.
You can spend hundreds of dollars on a video card. But if you're running business applications and surfing the Web, buy on price. The expensive stuff is for serious gamers.
If you regularly get the "Blue Screen of Death,"
you may have a random access memory (RAM) problem. This is also referred to as BSOD.
Note the message on the blue screen, especially the numbers. Check it in Microsoft's Help and Support Knowledge Base. Also, put the text of the error message in a search engine and check the Internet.
Assuming you can diagnose it, a memory problem is easy to fix. If you can't find the diagnosis information you need online, you can try swapping out memory sticks from another computer. But that memory must be the same type. If all else fails, take the old memory to a computer store. The people there may be willing to test it.
Sticks of memory go in slots near the microprocessor. They're about four inches long. Remove the old memory and match it at the store. Memory prices are all over the map, depending on type and speed. Be sure you get the same type.
When you press the new memory into the slot, you will probably have to use some force. The clips on each end will snap into place when the memory is seated properly.
If you boot up, and the computer cannot find the C: drive
, you might have a bad hard drive.
If you have another computer, swap hard drives to diagnose the problem. If your computer boots with the other drive, yours is probably bad.
According to techie lore, you can seal a nonworking drive in a bag and put it in a freezer overnight. That could shrink things enough to free them up. I've used this trick a few times and it's worth a try.
A regular back-up regimen will save you in case of hard-drive failures, assuming you aren't backing up to the same hard drive. If the drive is dead and you don't have a back-up, a computer shop may be able to save your data.
Your hard drive is in the front of your machine. It will be about the size of a paperback book and is probably held in by four screws, two on each side. Power and ribbon cables connect to the back.
Put the new drive in and install it as the master. Reconfigure the old drive as the slave. The instructions that come with the new drive should explain that. Boot the computer and install Windows on the new drive. If you're lucky, the computer will see the old drive (it will be D:). You can then transfer your data to the new drive.
Replacing a hard drive is more difficult than the other operations. However, if you pay to have the work done, it may not be cost effective. You might be better off buying a new machine. So if you are adventuresome, and you have the time, changing the hard drive may be worthwhile.
Know your limitations
Some things may be beyond your ability
. For instance, upgrading a microprocessor can be dicey. Even if a faster microprocessor will fit in your motherboard, you probably need to upgrade the BIOS (Basic Input Output System). This is done through a process called "flashing," in which information is downloaded to change the BIOS. If flashing isn't done correctly, the computer can be rendered useless. Leave that to the experts.
There are times when fixing a computer just isn't worthwhile
. New machines can be had for less than $1,000. That might be all you need for business purposes. So, if you're facing a $600 repair, maybe it's time to look around. That repair probably won't be the last.
Knowing that most people do not back up their systems
, let me take this opportunity to recommend that you do back up, especially if you have critical files that you cannot afford to lose. An external hard drive can be had for around $150. These connect via USB cable and come with backup software. Installing them consists of nothing more than putting a CD in your CDR player and plugging in a cable. The cable comes with the drive. I currently have 2 external drives and use one for backup and the other for additional storage.
