For about the past week or two I've been having problems with my computer. Chrome has been crashing and when it does I have to reboot because it says the program doesn't exist. Also most of the icons on my screen disappear. I noticed this time around that my "C" drive was gone. Sometimes when I go to reboot it just shuts off the screen and doesn't shut off. I'm not sure if I have some kind of virus or if it's the harddive failing. I've checked my BIOS and it's up to date. I ran malwarebytes and nothing there.
I'm running Windows 7 Ultimate (64) and have 3 internal HDDs. The "C" drive is a Western Digital 500 GB.
Any help or ideas appreciated.
