GRRRRRRRR...I WANT TO SCREAM AND YELL SO BAD...

Well I bought a digital/ web cam combo thing and I pluged it into the USB port and it says my connection failed!! GRRR. I just don't know what to do....I think i'm going to have to hook up my old Webcam and sale this one or something b/c I can't get it too work..times like this I wish I had a Computer Knowledgable man around the house.
I almost LOST it today.I had to put the babies to bed early b/c I just couldn't take it anymore. I thoiught I completely screwed up my computer b/c i couldn't get it to connect on the internet then something told me to restart it..well it froze so i had to manually click the power off and then back on and the internet is back up and running...Now, To figure out this damn Digital Camara i bought today. If anyone can come over here and plug it in for me....I'll buy you lunch.
