A mistake or inaccuracy, an error is caused about by committing miscalculations on the things that you do. It is a state of having a wrong judgement or conception in your conduct that allows catastrophic things to happen. In machines, error is a way to measure the difference between the observed value or the computed value of an event against its real value.

It is a deviation from correctness and accuracy. When errors occur, machines crash, computers freeze and softwares stop working. Errors are mostly unintentional events to happen. Most of the time, errors are a result of poor management and preparation.

Most computer errors are identified as internal to the server and not actually concerning the hardware or any device that can be of concerned to the user. One example is a system error where the problem violates the procedural rules. System errors are not recognized by an operating system and it notifies the user with the message, “A system error has been encountered. Please try again.”

A system error can be fatal and it happens when an operating system stops for a moment because it is in a condition where it is no longer operating safely. Some of these errors are stop error, bug check, system crash and kernel error.

Fatal error is triggered when the processor returns an exception to the operating system that causes a program to abort. This is in turn dealt as a fatal exception error which is non-recoverable. Usually, this error happens when the user is trying to start the computer, shutdown Windows or running a program. When this error occurs, the Windows system must either be restarted or shut down completely which will cause users to lose any important data that the offending program was processing.

Here are some common causes of a fatal error:

  • The user comes across illegal instruction.
  • The user is trying to get into invalid data or code.
  • Invalid privilege level of the operation.
  • An operation is not allowed in the current CPU setup.
  • A program is trying to divide by zero.

From the Forums

A user in the forum details it further:


The computer hasnt even started loading windows yet. It's not a big deal, but it seems like very odd behavior.   This has nothing to do with Vista whatsoever. Of course, I had my mouse and keyboard unplugged at the time, because I had just unplugged everything to move the computer. It is completely normal, really, and whatever OS you have, its going to do the same thing.  

My question is, what is with this error? That's what the system said, in DOS, on the black screen. As you said it showed up on the black screen with white text, which is the boot screen.

Anyways, I plugged the keyboard and mouse in, restarted the computer, and everything started normally. Keyboard not detected, Mouse not detected. The computer recognises this, and given that they are important, it puts a warning up that there is no connection. Fatal Error, System Halted.

Vista can't boot up if I don't have a keyboard and mouse plugged in? The fatal eror occurs because you have no input device.

Corrupted system files in the Microsoft Windows system can happen and it shows in the system error reports. Though an easy solution will be to reboot your computer, the better way is to repair the corrupted files.

No boot device detected: system Halted

When I start up my computer ( I am running xp home) when I turn it on I get a whirr sound in my cd disk draw and then I get the message "No boot device detected: system Halted"

I installed a disk burner onto my computer ("liteon" 52x32x52" nero software for the burner..) Could this be the cause of my problems? If you don't know how to get into BIOS, turn on your computer, and press F2 or delete repeatedly BEFORE the Windows screen appear.
I haven't been able to use my computer since I have got this problem.

Cheers Claire


Welcome to TF Claire! Please help!! Are you able to get into the BIOS at all? If so, try changing your boot sequence to start with the HDD.


System halted - Alert! Incompatible processor detected

I downloaded all of the latest drivers from dell, so I thought I did... So after I extracted the files for the A02 driver and rebooted my pc, I got the message almost immediatly,"System halted! I went to the dell drivers page and was going to update every single driver I saw... The problem is with the motherboard, not the CPU.

You might try booting to SAFE MODE to see if that will work for you. If not, start looking for a new motherboard on eBay, or go to someplace like PcSurplusOnline for a used computer or PCSolutions
 

nothing at all gets processed? So since the drivers didn't seem to work for me,..

But otherwise, I think your motherboard is done for. So what is my alternative method in your opinion? Sorry for the long intro.

As you have now discovered, installing a BIOS is a dangerous process, and you may have destroyed your motherboard. Newer boards have protections against BIOS installation errors, but older computers do not. As I was reading the other thread about the same situation, I found that none of that would work because the computer never actually boots, so all of that trying to reset the jumper and taking out the battery has no effect since the A02 driver is the only one I have on the system and doesn't recognize my processor, which I'm assuming... relatively same advice from all.

Alert! Everything looked in working order until i realized that I had no sound coming from my speakers. Incomp...
