usb ports and sound card don't work properly
Hi. I don't know if it's the right forum. I got a hardware issue. My computer has started screwing. When I booted I got a message about checksum being bad and options to change settings or load defaults. I got it few times, then it booted normally. Then after a while I noticed I have no network connection. The usb port suddenly stopped working. I connected the modem to another port and it worked. After reboot I had no network connection again. So ethernet is the only way to go. But the main problem is not usb ports. I have no sound since then! If I turn volume up or down, the volume bar in Debian doesn't fill at all, it's empty. Any ideas? And it's not a software problem. I have no sound on Windows either.
