Now i decided to get QuickCam Pro3000 ( thanks to people at this forum and their advice for other people ). Its a great camera, and i was happy!. so i install latest drivers, and software.. and it was working!! for about 30 seconds!! and then it FROZE AGAIN!!! so i reboot, open it up again, and it was working again .. till i clicked advanced options.. and the program and video FROZE... i keep having this freezing problem!! So, i thought i was having usb issues.. so i installed the latest 4in1 drivers for my VIA chipset... and it didnt fix anything i would greatly appreciate it if someone could help me !! thanks!
