Msi StarCam Racer HP Photosmart C4280 I don't now why but some usb devices, except keyboard and mouse, like wireless card and hub devices, are resetting or stop working properly. For example the most annoying is when my wireless card stop responding to internet connection with my router ( although it seems to be connected to local lan but with limited access ) and i have to reset it from windows or unplug and plug it back . I've checked event viewer but I didn't found anything usefull. Also try rearranging usb ports, or remove any unnecessary devices, without luck. Drivers are all up to date and no windows updates left to install either. Could it be a mobo issue? Because it's really hard to find a new 775. If anyone had similar issues in the past or knows any workaround on that please be nice and share Thanks in advance.
But i have nothing connected on the case usbs. Everything is on mobo ports. For example since I post this thread everything's working fine. It's completely random. I'm thinking on buggy drivers which is really frustrating cause i can't do anything about it.
