No Sound in speaker , Failure link to external

[ingwingfingerling 0]

I firstly dont know of any free software that gives a detailed list of all pcs drivers etc . I am using Xp Home.

The problem I am having is that I am getting no sound in my speakers , headphones .

My external aint responding either

I can download , access web , burn cds and dvds

I am also getting poor performance from my graphics card

 

Look I know this is absolutely vague and no help so If someone could help me get this sorted I'd be so grateful .

 

I have run antivirus , spy removers etc .

 

Plleeeaasse Help me !!!
