The thing was shutting back down again during boot up, I did it again and it happened at the same point so I knew it was a software issue. But the only was to get my data back was to boot it up on another HDD and transfer the data. I did have a backup of my business related files on my 40gb but it was a couple of days ago I last backed up so I prefered to just put the extra work in and save everything.
As for the blue leds, I had that new case lying gathering dust, and was going to spend the night on it anyway so I put some new toys into it in the process of fixing it.
I guess the lights dont really improve performace but the old case had one fan excluding the heatsinks fan. The new case has 2 80mm infront of the hdd bays and a huge 200mm over the top of the case, so it should improve the performance and life of the system. I am also going to get a 120mm for the glass door. So its now a 3.2 GHz P4, 2GB Ram, 540GB HDD, with a saphire GC.
To keep this on topic though, if you have allot of business info on your PC backup every day.
