Im not sure where youre based, i'm in essex so its probably not easy to help if youre in London. I always keep a load of tools for dealing with these kinds of issues- one such tool would be a dvd bootable copy of a linux distro or a disc called hirens which has 'mini xp'- then one could load up the computer with another os to quickly check if the mouse functioned ok outside of windows. The other bonus with a linux distro is you can access the file structure with none of the problematic windows malware slowing things down. Its normal for a laptop fan to spin at 100% for a few seconds at boot before it reduces. If it stays on full its likely the heatsink is clogged or theres a thermal compound or sensor issue. Sometimes the Bios has a setting to run fan at 100% when on AC power ie plugged in. Then re the trackpad - the only other thing that springs to mind thatcan disable the trackpad is the relevant FN key combination but that tends to turn the whole thing on or off.
