My computer would continuously reboot. I disabled the hard drive like another person told me too and now there is just a black screen that comes up when i reboot it that says Boot Agent
Operating System not found.
What do i do?
Hello,
Please re-enable you hard drive. More often then not when a computer continually restarts, a reset button is stuck, or the power button is stuck.
Less common, the power supply cannot supply enough powerage to the main hard drive. Solution: change the power cable feeding your hard drive to another power bundle with unused power plugs. If that fails your power supply is in serious question.
This type of symptom is rarely serious other than your lose of productivity. A qualified tech can get you straightened out in no time (a few days at most).
If you have any further questions or need clarity please don't hesitate to comment back to me and I'll be more than glad to help get you fixed... which is what we do here.

The rebooting as I illustrated could be rebooting because of a stuck switch, and this is the most common reason. Give your reset or power switch a good snap with your thumb. Your switch may also be damaged due to fatigue. If your machine is rather new then it is a serviceable complaint.
Do you feel qualified to open your PC and get your hands inside to switch over the power cables to your hard drive?
Sorry there is no easier answer, but after re-enabling your hard drive and the problem returns the power to your hard drive could be insufficient to run it and the system and the power supply resets itself. Your hard drive's internal motor may be responsible too. So, when ever there is data on a drive that you must have and you have a problem such as this I would ask for the name of a good tech or contact one you trust. We also have a repair directory on our home page. You can also ask through your chamber of commerce and check out a company via the BBB online but neighbors and friends, relatives are your best source of finding a good tech.
Good Luck and if you have a further question or need just comment back to me and I'll be glad to help.

Okay, thanks for setting me straight on having a laptop, sorry. Have you held the power button down for at least five seconds?

The next thing to do in this sequence of troubleshooting would be to remove external power, power off by holding the power button down for five seconds and then removing your battery.
Leave the battery out for awhile, a hour or so. Reinstall your battery, do not connect external power and power up normally. See, if things remain the same or not and let me know.
Question: do you have a bootable CDROM disc, such as your Windows or Recovery CD? Otherwise, do you have a floppy device to either swap out of your CD drive bay or is it permanently a part of your laptop.
Clearly, I haven't looked your machine over at Toshiba and won't until needed.
The reason I ask about the bootable CD is too see if your machine will boot to another device instead of your Hard Drive. So, let me know please. Thanks.
Lastly, what we see when we look at your problem entry it shows you selected a motherboard with a specific mode number.
So, since you have a laptop could you post the model number and let me/us know if you have Vista or XP and if you have XP or Vista did you install the Vista SP1 or XP SP3.
Thanks,
Worldvet

Hello,
I would let it proceed with option 1 and when and if it Alerts you that Windows is already installed you should see an option on the Alert Page that is titled 'repair'. XP is really good at repairing itself.
I would give that a try because one of the first routines the installer runs is a disk integrity check and if there is a problem with your hard drive this would confirm that.
As always, ask me via the comment box if you have any need for more clarification.
Sorry, but I will be on and off the computer this day as I do work on Saturdays and have to run out and take care of problems for people and can be away for a few hours at a time.
Regards,

Test your PSU or replace it if your power supply units fan
is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including
electrical extensions,IDE,SATA
the leads from your
"((motherboard to your hard drive))" make sure they have a secure connection and
are not faulty or just replace them they could be faulty
make sure all leads that
are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections
and are not faulty even the electrical extensions or just replace them they could
be faulty a computer
needs its connections to continue its cycle and have an end so any faulty leads
will end up with a computer error hope this helps

Okayy, I re-enabled the hard drive. Now the computer just keeps rebooting.
The power button is not stuck.
And my computer is a laptop not a PC so i don't know what to do...
It won't even shut off. The power button won't let it shut off.
It's okayy. Yess i have held the power button down for at least five seconds.
I do have a recovery disk and have tried to start the computer on it. Although, there were two options. One was to install all of the default programs, or another one where data could possibly be lost. i did not want to take the chances of loosing everything on my computer so i did not start it up with it.
I have a XP.
