Does my computer keep updating shut down
The problem is, if there are two programs clashing, there is not much you can do to stop this.. For this reason, when installing absolutely anything on your computer, including a simple toolbar, I recommend you create a restore point for safety reasons. Anyway, if you see that flashing cursor you are almost guaranteed that your computer will boot from a CD or DVD. Of course at this stage, when you see the flashing cursor, it is too late to insert the CD, and it is too early for other remedies.
People are often aware of a faulty DVD drive because you might have had previous problems removing discs or opening the contents of a disc.
If this happens and you have either Windows Vista or Windows seven, your first port of call would be to insert the operating system disc.
Although Windows xp is a bit more difficult to deal with, both Windows seven and Vista will repair most problems for you. This can happen after installing almost any piece of software including Windows updates, believe it or not!
Years ago I had a computer that was hit and miss when starting up.
Sometimes it would boot to black screen with blinking cursor and then other times it was fine. The computer was performing Power-On Self-Test (POST) and was not finding the cd drive occasionally.
When the average computer user sees a black screen on startup appear on their computer monitor panic immediately sets in.
