Actually this is a source code error, Meaning thatyour proccessor is sent a packet of code and it was not properly handled. this can be caused by the adding and removing of the same software a couple of times and the pathes are broken and confusing your proccessor and causing it to shut down and may also be caused by spyware/malware that was improperly removed. Another issue that may cause the same problem is that you have an out of date bios on your motherboard. or it could be a combination of all the above..
To get to the bottom of this.. you need to reboot your pc and as soon as the graphics posts shows hit the pause button on your keyboard to lock the page. If you miss do it again. In that writing is a BIOS version and date. write that all down and then go to your mobo manufacturer site and see if it matches the latest bios version that they have listed there. If not then you will need to update your bios. I would suggest that you get some personal tech help here if you are not familar with doing this.
It is very easy to mess this up and if you do you will be out a motherboard.
Now if you decide that you wish to attempt this then I suggest that you look at the bios manufacturer and go to their site an read very carefully the proceedures for performing a bios update. There are some utillities that does make this easier and safer to perform and it will be linked at the manufacturer's site.
Before you try the bios update you may try to do a simple fix with a regestry cleaner. I use regscrubXP and it is safe to use. Download thefree program and open it. In the upper left corner will be a tab "REgscrub finds problems" Click on that and just let it run..When it is done the tabs at the bottom will open and on the bottom left is"Fix all problems" click that one and let it do its thing > If this has not been done on your computer don't be surprised if it finds several hundred issues< After fixing the problems the file is backed up and can be restored later if need be****I have never had to restore an issue using this program***** Just exit out and reboot and watch the speed up of your computer and just wait to see if it locks up on you again. If it does then you will know it is the bios.
Here is the download; and a few others to clean up your system with.
