I am at a loss to what the cause of this is.

I will will be playing team fortress 2 and for about half an hour the game is fine then all of a sudden it starts stuttering madly every time it has to access the HD. It will not cease once it has started and the game becomes unplayable.

Also if I am playing streaming videos online the video will pause while the audio continues and then jump to the correct point again after a few seconds. This will happen a cpl times every minute.

Also when typing in boxes like this the words will freeze for a few seconds before spewing out in a big chunk. Also when scrolling a webpage the same thing happens. I will scroll and it locks up then I keep scrolling and the computer beep noise sounds from the mobo then it unclogs again.

I have now tried reinstallling windows several different times with two different windows versions and also on two different hard drives and still no change.

I didn't have this problem before but I had to reinstall windows cos it was screwing up for other reasons. Now that is fixed (fingers crossed) this thing has cropped up.

I require some new input as I've tried all the variables I can think of at the moment.

Another problem which is stopping me from trying the graphics card is that I tried updating the drivers but when I pick the new drivers they lockup youtube videos and cause a reset. I've tried it with several different versions of catalyst and each time the same problem .

I have a radeon hd4650. My default catalyst drivers I got with the card pick '4600' series as the correct drivers. Now with the new catalysts they have the option of 4600 series as well as 4650 (my box clearly says it is a 4650). So when I try the 4650's it appears to work in games but does the reset thing every time with youtube vids. When I try and pick the 4600 series from the new drivers the driver appears to be the same version as my OLD driver when checking in the display thing
.

I thought it was maybe something to do with HD but if I installed on two diff HDs I don't see how it could be that. Also two diff versions of windows, fresh installs and exactly the same thing.

Maybe it could be a graphics problem but if the drivers don't work what can I do?

Any other ideas?
