I've had my computer for about 5 or 6 yrs, I installed a new harddrive about 2 yrs ago. About 2 months ago my computer started shutting down by itself, now when it shuts down it makes a funny beeping sound and the green light on the p.c. stays on but the monitor light turns yellow and the screen is completely black or says NO SIGNAL. At first somebody told me it could be the fan, so i installed a stronger fan and cleaned out the harddrive to start from scratch. The computer was good for about 2 weeks and then started shutting down again. I checked on the RAM cards and they seem to be fine. The computer does not have any set time that it turns off, sometimes it shuts down within an hour and sometimes it can take 5 hours. Lately it's been shutting down pretty quickly, its also been freezing on me wich is funny because the first time it wasn't freezing . I have Nortons Antivirus and Adaware but the PC don't stay on long enough for me to run a full scan. Time 4 a new PC ?

The RAM could be bad. If you have Multiple Sticks you can pull one out and leave one in and see if it works properly - then switch and repeat with the other one.

PC Problems:
There are many possible causes for PC problems:
Hardware failure
Disk/File corruption
Virus, Malware, Spyware, Trojans, Bot Hi-jack
Registry corruption
Windows O/S corruption
And many more...
>>>>>>>>>>>>>Hardware Failure<<<<<<<<<<<<<<<<<<<<<
Check all of these!
Make sure you use a Surge Protector.
This kind of problem is often hardware
related though not always.
Could be a power supply problem.
Could be other hardware problem.
Sometimes the motherboard, RAM, or the
video card causes this type of problem.
Make sure you have the latest BIOS flash
and device drivers.
Could be getting too hot also.
If you are running XP disable
Disable Automatically Restart
in Settings for Startup and Recovery
under Advanced tab in System Properties.
See Control Panel.
Next time it happens look at Event
Logs to see if a reason shows.
If you are getting a STOP message you
can probably find some help here,

Try this:
Windows XP Repair Installation
At some point you may need to repair the installation of Windows
XP. This is preferable to a clean install in many cases since it
attempts to only repair your copy of windows without having to
delete all the files on your computer first. In many cases a
repair installation is enough to fix the problem. A repair install
deletes the files normally installed by windows XP and then
reinstalls them off the disc. A repair install will not rebuild
your computer's registry, delete applications and user settings,
or fix problems caused being caused by a program.
1. First you have to boot the computer with the Windows XP cd in
the cd tray. You will see a black screen and it will ask you
to press any key to boot from the cd so press the spacebar
and your computer will boot from the CD.
2. After a moment you will be taken to the Windows XP Setup
screen. Though the second option says to repair do not press
R. Instead press enter to select the setup for Windows XP.
3. Next, you have to accept the license agreement from windows.
Once you've done that it will search for your existing
installation of windows.
4. Once it has finished detecting the installation you need to
select the XP installation you want to repair. You can repair
the installation by pressing R. If you don't see the repair
option you will need to do a clean installation. Your version
of windows may have been damaged in a way that it cannot carry
out a repair.
5. Setup will then copy the files it needs to the hard drive and
reboot the computer. A message will come up asking you if you
want to boot from the cd, don't press any keys and just let
the timer run out. The set up will continue and look like is
doing a clean install but all of your applications and
settings will be intact when it finished.
An important note is to not activate your windows over the
internet right away. Always enable the XP firewall to protect
yourself.
>>>>>>>>>>>>>System Recovery<<<<<<<<<<<<<<<<<<<<<<
If you are using Windows XP you could also try a
System Recovery:
Left click on Start
Left click on All Programs
Left click on Accessories
Move mouse pointer over System Tools
Left click on System Restore
Follow the instructions and pick a restore date
when you did not have the problems you are now
having.

Sorry, wish there was an easier answer but there isn't
"one size that fits all!" Kind of like the car problem
that never shows up when you take it in for repairs.
Have fun but be safe!

Could be time 4 a new video card. When your PC is on and you get the "no signal" box on the screen, usually means your video card went south.
I would start by replacing your video card.

That sounds as if your video card or,monitor is going bad.
You might try going to manufacture site of the computer and looking for updated video drivers .Also,you might try hooking another monitor up to the machine.

It could be the hard drive failing. Consider backing up all your important stuff NOW...if it is your hard drive, when it finally goes, you will lose everything.
My pc kept shutting down in the summer when it got too hot. I assumed it was just the heat and to be expected. Trouble is, every time it over heated, it was being damaged further and one fine day, I lost everything!!
