your windows is corrupted.
please install your windows again.
an if you don't want to loose your personal data,then only format the "c" drive of your computer.

hello, how long have you waited for something to happen before restarted the system?
in any event, try resetting the BIOS. this is how: unplug the power from pc, wait 10 seconds then open up the side panel of the PC. First thing to do is to make sure you r not carrying any electrostatic charge (sound complicated? well its not) before you touch anything on motherboard in the computer just touch the metal part the casing and you are done.
now, locate the round ( coat button size) battery and gently take the battery out with paper clip, then look around and your will a jumper around that battery area. note the jumper position, if jumper is on first two pins, remove it and put it on last two.
Now plug the power back to PC (yes battery is still out)and press power switch (note PC may power on or may not) then 3 seconds later pull the power cord back out.
now, move the jumper back to its original position and put the battery back in, plug the power back and test computer.
hope fully this would do the trick, and if not, we might have to perform other tests like bad memory chip, BIOS update etc...
Post your results, good luck

Setting up a sata drive is not hard. shut down the power to the computer, make sure that power is off and make sure you disconnect the monitor cable from the back of the computer. Open the case up install the cable for your sata drive onto the sata1 connector plug in the power cord for it, and then mount the drive into an empty slot.
Hook everything back up turn on the power and go into the bios and make sur that the bios can see the drive. If it can then your sata should be setup and ready to use, however i don't think this will actually solve your problem.
You never said if the computer keeps booting before the operating system starts or if your computer reboots after the oprating starts. If this is happening after the operating starts, then chances are that this will not work.

Your optical drive might be dirty or bad. Try an official Dell disk to see if it will read it, especially a Dell drivers and Utilities disk. Also try a boot flash drive or boot floppy(since your system is a older) to get the system up. If your system comes up any of those ways, I would try a disk cleaner. If that doesn't help, then you probably have a bad cd drive. You could also look in bios setup to make sure the bios is showing your cd drive. It should list it there somewhere. Probably on the first page.
