I can't speak for everyone on this forum but if you've purchased a PC recently or built one yourself I'm 99% certain it will have SP2 on it. I bought a HP last March and it ran fine up until November and then it developed a few problems... Bad BIOS Checksum and No Input Signal to name two of them. No one has said anything about SP2 causing either of them.
