speachless, crosseyed, ellieoop, Old Biddy: I dont know what you have tried, but give this program a go...I instal it on all PC rebuilds i do, it will certainly get rid of any rubbish slowing your computer down.........

Piriform CCleaner

You have to set it up, by ticking what boxes you want it to clean, but it VERY straight forward

(the only ones i don't tick are Passwords & Wipe free space, but each to their own )

Also note, their is also a program included with CCleaner, that will clean your Registry. Cleaning Registries is not always advised, but as long as you back it up first it should be no problem. I always used it and have never had any issues

Is all this will do is make sure you computer is clean, so can run as best it can. It won't help, server issues or connection problems
