Hello folks,
A newbie need your help!
Asus P4P800S with Intel 2.8 Prescott, 512 DDR 400, 80GB Seagate SATA, basic agp 4x, XP, 56k modem card
I built up the computer myself and it has been running perfectly for 8 months. No hardware changes in that time. Booted up the computer, got "Bad checksum error" message. Put in the Asus cd, it found psp800.rom and reflashed. Re-started the computer and the monitor didn't come up. Pressed reset, rebooted, monitor cam up with "Bad checksum error" message. Reflashed. Restarted computer and the monitor didn't start up again. Sudden electrical smell from the p.s. Obviously all caused by a faulty power supply! Purchased a new power supply, install, boot up. No monitor and that nasty smell again. Another dead power supply! Use flashlight to examine mothernoard and find a hole burnt through the South bridge controller!
I'm thinking either the south bridge was faulty or something controlled by the south bridge is sinking a lot of current! So what are my options? Obviously need another power supply and another motherboard. Should I go for another P4P800S ? Anyone recommend another socket 478/agp/ddr400/sata motherboard?
How should I proceed without burning out a whole lot more equipment? How can I test the things controlled by the south bridge without doing more damage? Looked for wiring faults? Can't find any shorts. Check cards. No visible signs of damage on the agp card, the sata hd or the modem. There isn't anything else.
Did a local search on "south bridge" but nothing similar reported
All advice gratefully received.
Ross.
