pc reboot on be each time i start it up

i have a problem i never had before, on til i had a problem getting window to load
it seem my hard drive click a couple time, then i see BIOS and all the screen
then it try to load window and then it reboot on me, and i get a no choice screen start normal, safe mode or using last known good configuration


also
i have the save problem some time when i put a cd in my cd-rw rom and cd-dvd rom, it just reboot on me
no reson or error show up, just boom and reboot

Make sure all connections, cards, and RAM are securely connected and firmly seated.

If those are ok, then do a barebones by installing just the power supply, MB, CPU, RAM, video card, monitor, and KB.
If the system does not restart, then install all other cards and drives one at a time until the problem resurfaces. The last item installed is the cause.

If the problem happens with a barebones, then either the power supply, MB, RAM, or video card may be bad.
Check the MB for any bulging, leaking, or ruptured capacitors.
If they look ok, then either swap out these components, or have them shop tested.

My guess -> power supply.

"then it try to load window and then it reboot on me"
That suggests to me that there is a problem whilst attempting to load Windows [a Windows software problem].

Which version of Windows is installed?

"i get a no choice screen start normal, safe mode or using last known good configuration"
Are you saying that you are given these options to choose one?
If so, choose "last known good configuration".

Are you saying that you're trying to boot from the Windows CD? If so, then is the CD drive configured as the 1st boot device in BIOS?

Also it sounds to me typical of a dying power supply or bad capacitors, or overheating problems.

If you have a spare power supply or can barrow one see if that helps.

What are the CPU/system temps in BIOS?

Look at this thread (http://www.pcguide.com/vb/showthread.php?t=25482) for pictures of good and bad caps.

Overheating is my guess...as that is exactly what my machine was doing two days ago...until I changed out the heatsink/fan and added another case fan (the old heatsink fan was actually cutting out and only working part-time).

Learn How To Diagnose Power Supply Problems

The Power Supply convert's your regular household current into low DC voltage used by the computer. When this component fails,there is simply no activity going on wih your computer. Remember to do the easy troubleshooting first. Inspect the Power Supply for any damage. Double-Check all connections.

Learning how to check your power supply and how to replace it when needed can be a life saver if you're a computer buff or in business with the trusted PC. Don't take for granted the simple pleasure of turning on your PC and everything works just fine.

We turned on one of our computers recently and in about one hour, it just re-booted itself. And it continued doing so about 10 times a day until we found out the power supply was the culprit. Things to look for when your power supply is going bad or just dies on you are the following.

NO POWER TO THE COMPUTER

Here you must first check the wall outlet for power by connecting another device such as a radio or lamp to be sure power is present. If the computer is connected through a surge protector,check it as well.

If the wall out has power,check the power cable going to the PC to see if AC voltage is making its way to the system unit.Do this with the use of a multimeter.

If there is power,you will have to open the PC and check for power from the power supply to the motherboard.

When using a multimeter to check voltage,be sure you have a good ground for the black lead of the multimeter.

RE-BOOTING PROBLEMS

One main problem you may face with an ailing Power Supply is that it may re-boot the computer without any warning. All information is lost and it seems as though this happens at the worst possible time.

Booting errors when the computer first start's up is another indicator of this component going on the blink.

POWER DISTRIBUTION PROBLEMS

When the power supply begins to fail, you may receive power at one device and not another. For example, the Hard Drive may receive power but the CDROM Drive has nothing at all.

Another headache with would cause re-booting is the intermittent power going to the drives or the motherboard itself.Follow the steps below to check your power supply should you experience some of the above problems

OK HERE HIS RELY
Hello Sir,

Yes,the power supply is famous for this.It will
stop working all at once,re boot without warning,
as you said,and they will allow some components
to work while others won't.

You can check it with a multimeter but the results
will not be conclusive




BEGIN TO THINK MY REBOOT PROBLEM ANY TIME IT WHAT TO, AND MY PROGLEM BOOTING UP WINDOW AT STARTUP ARE POWER RELATED

[Sylvander]

That possibility is easy to test out.

Just boot an OS [like KNOPPIX (http://www.knoppix.org/)] from a bootable CD.
If the OS [KNOPPIX or whatever] runs just fine, then there is no hardware problem. :)
If the problem is still there, then it most likely IS a hadware problem.

I only read first post seems a driver or hardware problem. This is the Windows that restarts itself.
Control Panel->System->Advanced->Start-Up and recovery-> Uncheck auto restart.

it was my power supply
replace with a 400 w att, and i have not had a bit of trouble rebooting
