do you have only one ssd like a storage?
do you have enough space left on your ssd?
did you recently upgrade a hardware driver? gpu driver or other
I have a SSD that holds my OS (Windows 8) and a 500GB HDD that I use as storage. My SSD only has the OS and a few other programs installed. It's sitting with 122GB free of 223GB. My HDD on the other hand is nearly full sitting at only 2GB free. Do you think that could be the issue?
I don't believe I upgraded any drivers or anything. Everything's been working perfectly for a while now so I haven't needed to upgrade anything.
