Wow. Please don't use all caps like that on a post. You do know that's considered "screaming", right? And it may cause some experienced "answerers" like myself to completely pass your question up.
To use it to emphasize a word, no problem.
1) Do you mean true freezing (you're doing something on your computer and it suddenly freezes completely and neither the keyboard or mouse has any affect), blue screening, or just turns off and shuts down by itself? (if so, see troubleshooting below # 2))
(Side note: If the CPU is overheating (the true processor chip, not the whole case which some people call the "CPU"), you wouldn't know if was getting hot or not unless you had the case open and put your finger down beside the CPU cooler fan and felt the edge of the chip.
I have an infrared heat sensor for that kind of thing because I'm a professional Computer Technician, but I imagine you don't have one of those lying around.
What you're measuring (which you can't do with a finger (unless you don't mind, at best, a blister on your finger) is a tempurature called your processors "Tj. Max", which is at what temp. your computer freezes and/or shuts down. (or possibly fries)
For example, my current processor has a Tj. Max of 85C (185 degrees F)
However, depending on the chip's onboard overheating detection, it may not shut down in time, in which case your processor is fried.
2) Or do you mean it just SEEMS like it's freezing because when you turn it on all lights seem normal but nothing shows on the screen?
Simple answer for this one:
Make sure the monitor power is plugged in and has a good connection to the back of the computer first.
If still nothing, your monitor or video card is bad.
You'll have to have access to 2 computers to find out which it is.
Try connecting the monitor to a known good operating computer.
If the screen stll doesn't show anything, your monitor has gone bad.
Then, try plugging a known good monitor onto the "bad" computer. If nothing shows, your video card has gone bad.
Anyway, if it really is actually freezing, what you're talking about is normally caused by 3 or 4 things:
- Bad motherboard
- Bad processor (CPU) (You're saying C.P.U., which is what some people call the actual case containing all your parts)
- Bad RAM
- Overheating (dust build up (not that common), or, more often the CPU fan has quit working, in which case you should replace it immediately)
Bad motherboard - Motherboards do sometimes go bad but, in our shop's experience, that's pretty rare.
Bad processor - Also pretty rare for a processor to go bad.
Bad RAM - we do run into this one pretty frequently.
Overheating - Also a pretty frequent one.
I'm betting RAM or overheating problem. (If this is a true freezing caused by overheating)
If you're comfortable and able to do so, take the side of your case off, remove the RAM modules, and scrub the gold connectors with a pencil eraser. Not too vigorously, but you'll see them go from dull to shiny.
Now, put the RAM back in and boot up and see if that fixed the problem. I've had this little trick work MANY times.
To test the RAM while it's installed, which may be the method you want to use if you're not too hip on taking parts out of your computer. (I really don't know your skill level regarding this)
Very easy:
(I'm assuming you have Windows 7 or Vista)
Click on the Start orb and type mdsched and then hit the enter key.
Now click on the big "Restart now and check for problems (recommended) button.
Now, obviously, you can't run this Memory Diagnostics if you can't see anything on your screen, but put the RAM in another computer of yours or perhaps a friends and test it this way. Make sure to remove all RAM besides what you're trying to test.
If it fails the tests, you have bad RAM and will have to replace it.
So try all these things and find out what's wrong with it and fix it yourself.
I hope this helps you.
