Must....resist....your doing it wrong....joke....
I've been VERY lucky in that respect then
Only 3 times can I remember cocking it up.
1. Rebuilt a mates computer and then it wouldnt see any of the hard drives. EEP!
Turns out I hadnt put the damn power cables in
I spent nearly an hour bricking it thinking I was gonna have to buy him all new HD's!
2. I blew up an Athlon XP chip by thinking I could run it for like 10 seconds without a heat sink to trouble shoot something.
3. Back in the day before it was easy to update your bios. I did it to one of my Dad's computers and it nuked it.
Thank god it was like a P2 or something so he bought a new one lol
I'm sure there probably are many more but I just cant remember them.
