Hi,
-- This might help to diagnosing the problem,
I turned my computer on at 8:30am and kept it on till 4;30pm(16:30)
I did not connect to the internet nor opened any program, the computer did
not reboot, it went on so smoothly, but when I started working on a program
it went back to rebooting, also when I get connected to the internet and log
on to any link it went back to rebooting, I hope this might help in narrowing
the possible faults.

I would start by updating my video drivers. If no update is available,
reinstall the current drivers.

I am attaching the message I got after unchecking automatically restart.
-- Error message
A problem has been detected and windows has been shut down to prevent
damage
to your computer. IRQL_NOT_LESS_OR_EQUAL.
There's no single reason for this error, as it can be thrown by all
sorts of derrangements. This case is only one possibility...

....and you can exclude that by booting into a different user profile
(e.g. the hidden Administrator account in Safe Mode).
In fact, if not already done so (sorry, I'm late-to-thread); compare:
- Safe Mode Command Only
- Safe Mode
- Vanilla VGA drivers (would point to Frank's suggestion if OK)
- normal Windows, off all networking and peripherals
- normal Windows, off all networking
- normal Windows
I did clean my computer from inside a thorough clean, but still reboots,
besides the fan is working and as usual.
Are any motherboard capacitors bulging? Like this:

Going back in time, as top-posting does...

My computer suddenly went mad, while its on it goes off and onagain (reboots, restarts) by itself, although I have not reformatted or
changed anything nor installed any software or fitted new hardware, is
it getting old? I hope not, its four and a half years old.
That's the right age for bad caps, and bad power (mains, power supply,
and the "last mile" pump-up capacitors within the boards) will
classically cause hardware resets and lock-ups.
Unless you disable MS's default to "automatically restart on errors",
these will look exactly like software crashes that would go with bad
software (predictable reproducability), bad HD (may show predictable
repro) and bad RAM (totally unpredictable repro).
If you still have sudden restarts (as opposed to proper shutdowns that
were spontaneously initiated) after turning off "automatically restart
on errors), then that really does point towards a hardware issue.
Eyeball caps, then do a 24-hour spin in MemTest86 with that boot CD
removed after the tests start. If you come back the next day and
MemTest is no longer running, you had a crash or reset while away...
Right click My Computer and choose Properties | Advanced.
In the Startup and recovery section click Settings.
Uncheck "Automatically restart".
Amen! Now why didn't they do that by duuuuuuhfault?
Next time instead of restarting it will show you a blue screen. Copy the
error information and give us that, please.
Which is where this post started. But unless there's a reproducable
pattern, you may find you get different errors each time.
In that case, I would avoid running Windows (as every bad exit rots
the file system, can trash data etc.) until I'd checked the hardware,
as described, and also including the hard drive.
