OK
got Teef loaded up last night and managed to get onto a random server which had no players on it. ran around as the heavy dude shooting up infrastructure with the minigun just to see how it ran, which wasn't too great actually. Same prob running HL2, small stops, especially during cutscenes in HL2. Fiddling with the gfx settings seemed to lock the PC up for 10 minutes at a time with the HDD LED on full burn so I figure I'm having fragment / read speed issues.
Managed to get nto the 5punk server and piggybacked hehulk on spectate for 5 mins, but the lumpiness was still there. Tried to dumb down the res a bit but then it hung up completely.
Left the PC to defrag this morning (20% space free, 15% fragged) so we'll see if that improves matters when I get home.
Question (coz I've been thinking about doing this for a while anyway) how easy is it likely to be to upgrade the HDD?
I have a 4 year old (actually maybe 5

) fairly standard Dell Box
The current drive is a WD 80G
I have an external drive easily big enough to back up to (320G or something)
what is the process to swap in a new drive / add one?
Do I just plug the new drive into the 2nd IDE, mirror the existing drive onto it, shut down, put the new drive onto the primary and boot?
