system restore ?????

Hi to all, I have had a problem with my audio play-back within video files ( another story, see " sound problem " in the hardware forum if your interested ) anyway in my fumblings I seem to have altered some settings that I can not find again, oops!!!
My question ( at last I hear you say ) Is there a system restore or return to default settings program within windows 98se.
Thanks for any help given Alan

 

Thanks eddie, that at least has sorted out one of my problems.
Could I pester you for a bit more advice ?
I recently installed a new soundblaster card as I was having problems with my onboard sound. To save us both a bit of time ( and to be a bit cheeky, sorry ) my problem and a some data concerning IRQ's are posted on the hardware forum under "problem with sound??? "
A quick summary, I can play audio files from cd rom and off hard drives, I can play video and audio but the audio is very distorted, if I reduce the file to the task bar the audio plays fine. One idea was that there was a conflict on IRQ 11.
I'm not that savy so any more help would be much appreciated.
Thanks in advance Alan
