I see you are using Windows 7, you should try updating to Windows 10 and get the latest creator's update.
Its the easiest way to build support and compatibility for most mining rigs.
I was thinking to switch to Linux but i didnt know if is possible to overclock, but about windows 10 if the problem is in the windows i will try the win 10 then.
Yes Linux posible to overclock and its easy. Lot of tutorial for OC on Linux
And
try to change your HDD to SSD, use SSD 60 GB is enough and its cheaper
The problem is not in the SSD, the computer freezing and that stuff is something different, before i open thread i switch and try ssd but everything was same.
When i run miner it goes VERRY VERRY SLOW so i cant open anything other untill i close it, but i have 8gb ram and good processor so i hope someone will help me.
I didnt know is possible but if is the OS problem then maybe i switch to linux.
