Hey everyone, Well i got all my bits today, so i put my new system togther, being very careful, all went together fine, bootd her up, flashed bios to newest version, then checked the BIOS and everything wasbeing displayed properly, everything was recognized correctly. So i set CD-ROM to the 1st on the boot sequence, and got ready to install XP PRO, got to where you choose to format etc, and the pc died. So i started her back up (she wouldnt reboot straight away) and she keeps dieing at around the same point, Checked all Temps and they seem fine, nothing is over heating. (obviously im going from touching heat sinks and bios temps) Cpu was idling at 40c which does sound kinda high.... just hope the Temp is being read correctly, and im not burning up the cpu. The full specs are.... AMD XP2400 Asus A7VX8-X Kingston 512mb PC2700 Radeon 9800 pro 40gb HDD CD-RW 2 case fans Cooler master Aero 7 Generic 450w PSU As you can see from the list above you can see what i think the problem is, Crappy PSU that i got a with a case. So any ideas?
