I built my own machine about 10 months ago. I have a small SSD which runs Windows and a few other things and then a traditional HD (Western Digital 1TB). Today after I woke my computer up, it had a message that AVG had downloaded an update and the computer needed to reboot. After clicking ok, the computer started making a wierd noise and it had a lot of trouble shutting down. I've managed to pull the computer back up but I can't seem to access the traditional HD. The HD light is on almost constantly and when I pull up task manager it shows my traditional HD running at 100%. Any suggestions on what to do?
