Computer keeps shutting down engine every couple of minutes but restarts easily.

sounds like you could have a coolant temp sensor issue. If it senses the engine temperature higher than it actually is, it will tell the engine computer to shut down.

Also I'm not showing an 05 Eldorado, if you could give the correct information for your car, it would be very helpful

Have you stripped and cleaned out carburettor?
sounds like a blocked idle jet?

If I undrestand this correctly, this was a windows update? In some caese after a windows update, a restart is required and during shutdown and restart it configures that update. If the computer is shut down, "unexpectedly" or shut down before update is finished, then the update won't complete. If this is what happened, shut down computer by pressing power button on front of tower. Start system back up using on/off button. When screen comes up with options to start mormally or..., arrow up to "start in safe mode". Wait a couple of minutes and a window will come up "what is safe mode". Scroll down in that window until you see "what is safe mode", highlighted in different color, and click on that. It will take a couple of minutes, and another window will come up where you can scroll down to "start safe mode", click on this. This will take a couple of minutes and a window will come up with a suggested restart time and you will see a box "next". Click on the box. You should see the update in the list of things that come up. Click on the process just prior to the update and click "start or next". This will take a little time and will restart your system. When it comes up, let it think until you see a message "system restore complete", click on ok. Now you can click on start, find control panel and click on to open. In your list find "windows udate". Right click on and open. At the top left of screen you will see "check for updates" and click on that. It should recommend the update you just removed. If it it "important" check box, and install. Restart when update is finished and give it the time to do it's configurations.
If I misunderstood your problem you can let me know at "add a comment" or try reposting. Make sure you clarify between a "windows update" or a "windows upgrade".

cheak that there is no scheduled shut down

Mine is doing same thing

coil pack's change them that should do it they get hot shut down cool off they are fine

needs dealer computer ,sorry for the bad news but cars from 2005 use encrypted software

Your computer is most likely overheating.

Make sure it is positioned so that none of the vents are blocked on the unit.
Check it with your hand to see if it's overheating, make sure dust is not blocking the vents.
If the issue persists, could be software or a failed cooling system on the unit.

It would seem in my opinion from the information you gave, that your processor of graphics processor is overheating and shutting down the laptop. Possible the cooling fan is not operating correctly. Do you hear your cooling fan running at all?

Hope that helps.

Check your RAM. Do you know the program memtest86? You first download the memtest86 (easily found with Google). Then, you make a bootable diskette (or CD-Rom). The instructions are very easy to follow. You leave the diskette (or the CD) in your computer and restart it. You may have a result within few minutes. If not, do the test during the night. Once, I got an error message only after 8 hours running the test.

Give me some news.
