Hi. When i play media on my Dell D800 (streaming video or music) it has developed a problem where the cooling fan comes on very loudly and suddenly the processor slows right down. I have to re-start to get performance speed up again. Can anyone help me?

Re: Slow speed, fan coming on loudly in Dell D800
Yeah the slowdown is the laptop throttling back due to overheating.
When you do processor-intensive work like - streaming videos - the laptop overheats. The fans come on loudly.
When the computer heats up despite the fans, the processor throttles back to relieve the heat.
When you reboot your machine, it stops performing intensive work, giving it a chance to cool down. It's not restarting that fixed the problem it's the fact that the laptop cooled down.
So here's what you do. Get an air duster and blow all the dust and gunk out from your fans. They are most likely clogged with dust and that's what's causing your cooling problems. If there are large dustballs in there, use a tweezers and pull them out. Get as much out as possible.

If you place a dvd in your drive and play it does it play slow and stall? If so you need more memory. If not then the site you are streaming the video from might be slow or have heavy traffic.
Your internet service provider might have you on a slow line speed. AT&T has different line speeds for their customers. If you purchase the lowest priced package then your line speed will be very slow on downloading and streaming.
You probably need more ram memory. Also try playing a video in your dvd player. If it plays slow and choppy you definitely need more ram memory.
If you are trying to play a video from a website (streaming) then three things can affect how smooth it plays. 1) Memory - your ram memory might be low 2) The website might be experience heavy traffic from many users. 3) The Line Speed of your internet connection from your service provider might be slow. For example: AT&T sells about 3 or 4 different packages and each one increases the line speed for uploading or downloading. If you buy the low end package the line speed is very slow on uploading and downloading or streaming. It's ok for just surfing, but nothing else.
Does it freeze when you play a DvD on the system? if not, Video Memory is probably not the problem. I would say your problem is probably the streaming or downloading from the site you are watching the video from. Your line speed might not be high enough (for example, AT&T sells different line speeds and the lower the speed, the slower the download). How much main memory do you have? That might be a factor too. I would say you should at least have 1 to 2GB of memory.
There's a second fan beneath the keyboard, you need to pry open the top panel where the power buttons are, then remove 2 screws for the keyboard to come off. When I did this, I saw the second fan with dust blocking it. I used a vaccum cleaner and my D800 works perfect again. One reason why the top left corner fan runs at full speed is that it reacts to the other fan being disabled, kind of like an emergency detour for the heatsink.
