I assume this means they re-issue when the cd no longer works. (must see if my cd's still work - they must be around here somewhere).

We buy all our dells with Prosupport. I had the slowdown for ages - drove me crazy. Everyone at work blamed Linux (which it is running). Eventually phoned Dell up and told them to replace stuff until it worked. Next day they came in, replaced motherboard, cpu's and memory and it worked just like a new machine (strangely enough). Never had the problem again. Wished they'd replaced the case too - that scratch is bugging me. Maybe should drop it in a bucket of water and try again.
