Touchpad stops responding

hi every one

i have 2 main problems with my laptop

i am using dell studio 1537 laptop running on Vitsa Ultimate 64

1. my first problem is that sometime my touchpad stops responding for sometime and then becomes normal again

2.my second problem is that some times my sound service stops running. this usually happens when i try to play a video or audio file.

the service needs to be restarted again.

i have recently refreshed my windows but does not helps.

any suggestions.

thanks

You should check Device Manager for any troubleshooting or errors! other wise then go for any Hardware Setup

there is nothing i found in device manager and what do mean by hardware setup
