Basically the computer starts up fine, no beeps etc...

When it reaches the desktop i can click on icons to highlight but double click does nothing. I can't click on the ballon that pops up for updates, start button or even the menu bar. I don't know what to do. There is a RUNDLL error that occurs but i don't think its relevant to anything of great importance... "mykxyqty.dll" probably just a useless dll for one of my brothers games or something nothing about it on google.

Any ideas anyone?
