Throw the damm thing out the window...that will solve the gremlins,then your boss will have to get you a nice shiny new puter.
The most reasonable suggestion so far. Alternatively, switch to a company that hires competent IT staff. Unfortunately, in the last years, IT hiring has been dumbed down enormously - management seems to think that "it's Windows, anyone can handle that, so we might as well hire trained monkeys". To some extent, that is correct: even Microsoft certified experts often suggest desparate pseudo-solutions like "just reboot the thing" or "let's just reinstall everything". There's usually not much more you can do, since it's often practically impossible to find out what exactly the problem is. That's why many IT professionals hate Microsoft software passionately.
Buy yourself lots of Dilbert books in the meantime. They won't fix your computer, but they will lighten up your day.
