Question about Photoshop memory and CPU usage?

It probably sounds like I'm an idiot but I'm not very technical when it comes to system stuff - but I need help on this. I have my scratch disk set on my main drive because I can't afford to get another drive. Is it safe to do this and what is the safest setting to use so that it won't mess up my computer?

I just did a bunch of work in Photoshop and now whenever I open it my CPU usage shoots up to 100% and stays there even after I close Photoshop - it only comes down if I restart. But if I open PS again (even after restarting), the same thing happens again.

I don't really understand all of this, but I know the thing with the memory isn't good. Do you have any suggestions on what I should do? Is there any way to ''empty'' Photoshop's caches or memory or whatever? I realize I sound like a dimwit, LOL.

Help would be much appreciated - ask me if you need any more details. Thanks in advance! And please give any instructions in English that I can understand ;D
