Hey everyone. I am in a pretty precarious situation.

Recently my SSD stopped booting, so I am using a crappy 500 gb laptop hard drive because it has windows 7 on it. I just installed all the drivers and stuff etc, but when I load a game, the game freezes every few seconds, and it's consistent. Also, another thing is, this hard drive had like 1000 detected malware or suspicious things, which I've cleaned.

When I use a graph/tool to see the graphics card, I notice that when it freezes, the GPU goes from its 1050 mHz to 300 mHz, which is it's "idle" and lowest setting.

What can I do?
