Hello,

My computer screen flickers periodically. Well, it's not quite a flicker, the screen contracts and expands very quickly and it looks like a flicker. It does this mainly when I haven't used the computer for a long period. The flickering stops after about 10 seconds and then the computer is fine. Also the windows startup and shutdown music stutters/sounds unstable, like either the system is unstable or something is slowing it down. Other than that my computer works fine although if I have a lot of stuff running and I watch something on youtube or a similar site the sound starts to stutter in that same way on rare occasions. I'm sure it is not a virus or malware as my computer is up to date and I have done all the scans recommended on this website. I even had someone on this site run me through stuff to get rid of any existing malware on my computer not long ago. Can my problem be fixed or is it something I shouldn't really worry about?

Pls provide some details of the computer. Is it a laptop, as you say computer screen, or is it a stand alone monitor. If the latter is it CRT or flat screen LCD.
Please click Start, Right click, My Computer, click Properties, Click Hardware, Click Device Manager and check if there are any warnings - yellow mark, against Display Adaptor, Monitor and Sound

The monitor is a CRT monitor, and the computer that I am using is a desktop Dell Dimension 1100. I use Windows XP Home Edition. I checked the device manager and there are no warnings shown.

I suspect the flickering is the Cathode ray tube in the monitor.
If it is powered from its own mains plug, leave the monitor ON, ie: power to it, whilst the computer is OFF, ie overnight and see if then by powering the computer ON it still flickers. If the monitor is powered from the computer, ie: on a power in - power out arrangement at the computer then you will have to connect another lead. - depending on the power arrangement at the computer.
Alternatively, try the monitor on another computer. If the monitor has a degauss button try that first.

Please see this and check your driver situation. I realise you said there were no warnings but does anything need updating, albeit most are five years old or more.

I would also run this
