While attempting to look for problems with my hard drive, I used Windows Memory Diagnostics Tool and during the process around 2 of 2 80%. I heard beeping from my computer, which I suspect is from my hard drive. It beeped around once approximately every 4 seconds , even after the Windows Memory Diagnostics was done it still beeped for a while. From the description of the Windows Memory Diagonostics, I should of gotten the results telling me if my computer had memory problems or not. These results should of been shown after I got on. But when I tried to restart, it gives me the options to run normally or safe mode(s). When I attempt to run normally or in any kind of safe mode, my screen turns blank and only lets me move my cursor. I'm not sure if this matters, but I'm using an laptop.
