Having problems with your HP Pavilion S3420F Slimline Desktop PC ?

Computer won't use sleep mode anymore

\015 I am not a computer professional, I am just trying to figure out what the heck has happened to my computer. I have a HP Pavilion Slimline s3420f PC and it is running Vista on it. I have always just put my computer to sleep instead of shutting it down since I use it quite frequently throughout the day. About a month or so ago my computer decided it would not go to sleep anymore. I have tried just about everything I can think of in the power management settings and I even tried going into the device manager and modifying the ethernet setting and disabled the wake on lan setting but even that didn't work. Someone please help!\015
