Thank you Pangor, I'll have to wait until my bf is home to check most of these things as I'm clueless about swapfiles and all that other tech stuff. I'll show him your post and let him sort though it all. I don't think it's my fan (power supply) because I just bought a new one about a month ago. I still think it has something to do with a couple of pieces of software I've installed, so I'm going to remove and install them again and see if it helps. One of those was
photoshop, I was playing around with the scratch disk property's and I may have messed up something in the process plus I tried to re-load a bunch of my filters and plugins the easy way by copying the folder they were in after I reinstalled it. I think I doubled up on some, and also some don't work because they are missing files (dll's) which weren't in that folder that I copied in.
Yes Tormie, It's great to be able to come here and get help from people, even if I am too computer ignorant to do them all myself lol
Now give me back my coffee!
