Computer Problems and PC
Errors
Every PC user
has a computer problem now and then. Even the most stable, secure machine is
not safe from buggy software, failing hardware, or even the occasional loose
wire. PC problems can be a huge headache, bringing productivity to a halt and
potentially costing you money. Here are some of the most common computer
problems, and their possible causes.
The
Computer Won't Turn On
This can be a
computer user's worst nightmare. You hit the power button and nothing happens.
Any number of things can cause this computer problem — it may be something as
simple as a loose cord, or as serious as a dead power supply.
Another
common PC problem is when the computer turns on and the fan and lights come on,
but the machine doesn't boot, or shows a blank screen. This could be anything
from a dead (or unplugged) monitor to a dead hard drive or corrupted boot
sector.
Lockups
and Freezes
The infamous
"blue screen of death" has frustrated many a user, as it brings the
computer to a halt and displays an error message that's utterly indecipherable
to most computer users. Lockups can be caused by any number of issues —
sometimes it's buggy software, or a system running out of memory.
Sometimes
it's a bad hardware driver causing the issue. More seriously, it can be a sign
of overheating, RAM going bad, or the hard drive failing. Components get loose
inside the machine and can also cause computer errors, sudden lockups, or even
spontaneous shutdowns.
Slow
Performance
When you
delete files and applications from the computer, all kinds of junk can get left
behind. Useless files and data can accumulate and degrade system performance.
Ironically, antivirus and anti-malware software, while vital to the health of a
computer, can slow down a PC's performance. Low hard drive space or not enough
RAM in the machine can also cause computer errors and slow down the machine.
Strange
Noises
Is your
machine making a strange whirring noise? It might be a fan dying. Computers
accumulate dust over time, and when fans get clogged, they can slow down,
decreasing their effectiveness and making an unpleasant grinding sound.
Another
common computer problem is the dreaded "click" of a dying hard drive
— one of the most potentially destructive PC problems there is. If you hear a
rapid clicking or clunking noise inside your computer, it's best to get a
backup plan in place, if you don't already have one — chances are your hard
drive is close to dying and taking all your valuable data with it. Then again,
it may be a loose component or screw inside the machine. Either way, don't
ignore it.
Overheating
Dying fans,
poor ventilation, or even heavy use can create computer problems as the PC
heats up. Most computers are designed to shut down when things get too hot, as
a precaution against permanent hardware damage, but it can be pretty alarming
when a machine just switches off seemingly out of nowhere.
Overheating
can cause all sorts of other computer problems. Overheating can cause mouse
glitches, strange performance in software, or lockups, while an overheating
video card can cause the display to momentarily fail.
