I've just been given a spare hard drive that works great except for one thing. Whenever I move my mouse the monitor goes a reddy colour and sometimes has stripes. It's not my monitor, mouse, keyboard etc as they work fine when hooked up to my original hardrive. My refresh rate is 75 hertz my power is okay I guess because I run my comp on it with no probs.
Am I up for a new video card or could it be something else??? Any help would be greatly appreciated as it's a great hardrive with everything I want in it.
