|I have finally managed to solve my problem with the help of Acer support. I have pasted what they suggested. |
"It sounds like it may be advisable to perform a system recovery on your machine to rule out that the problem is a software related one. In order to do so, you will need to launch the Disk2Disk recovery feature (which should be supported by your machine). This can be initiated by pressing ALT + F10 when the computer is first switched on. You will need to hold down ALT as soon as the Acer splash screen appears, and repeatedly press F10. The window of opportunity is very small, so this may take a few attempts. The Disk2Disk recovery feature allows you to recover the system without recovery CDs. This will return your system to factory settings and will delete everything stored on the machine. If possible we strongly advise backing up anything important on your machine before starting the recovery process."
As I said this worked for me, and also as it says it clears everything stored on the machine ,which in my case was very little. So if this is any use to anybody be aware of the possibility of losing anything stored.
I would just like to thank everyone who took the time and effort to help me, a very grateful, and now relieved, DVD watcher!!
