I know this is a beta program so this is not a complaint, it is just for your information.
I downloaded Speccy v1.00.125 Beta from filehippo.com.
I installed the program and ran it. The details of my computer started to appear and then the screen froze, a blue screen flashed on for a split second and then my computer restarted.
I tried the program a second time a few days later from a fresh reboot and the same thing happened again. However this time my computer failed to restart. I turned it off and back on again and the Bios screen didn't even come on.
After a few minutes I tied to restart my computer and was successful. I have now uninstalled Speccy.
While Speccy was installed on my computer I also noticed a slowing down of the system, which since it was uninstalled has gone away. I don't know if the two things are connected, but I thought I should mention it.
