Unable to set default programs as it will not start

[dvtrv]

I have a Dell Inspiron 1525, intel pentium dual-core laptop running vista 21 home premium.

When I try to load up the default programs and select set you default programs it just sits there and will not load up.
I have it running for approx 30 mins so far and no signs loading. there is the green lign below which moves across the screen as it should do but nothing else.

Please, please can anyone help me?

Tank you,

Run disk cleanup to clear PC junk.

Deep your computer with your antivirus.

Try to run sfc / scannow (System File Checker). To run the System File Checker in Windows 7 or Vista, type cmd in start search box. In the result, which appear, right click on cmd and select Run As Administrator. In the command prompt window which opens, type sfc /scannow and hit Enter.

Let us know if it helps - maybe other will have other ideas ...
