MY PC has been fine since i got it but i removed sp2 because i heard bad things about it and ended up reinstalling it but now when i play videos or dvds they are all green in colour, like overlayed. In winamp it said remove hardware video overlay and i did and now in winamp its fine but every other program it is still green and i cant play dvds in winamp. What im asking is why has thsi just happened and how to fix it, many thanks in advance.
