hi please help me diagnose this problem.............. picked up this machine and it was not posting....the hard disk lite was locked on........i swapped out the hard disk initially and it posted straight away...dead hard disk i thought.......so i ran it overnight with diagnostics testing the hard disk to see if it would blitz it befeore i bought a new one....next day it was still going ok so i bought a new drive.....i ran xp setup and it formatted 33% of the drive and it stalled.....i restarted the system and it didn't post again.... Gigabyte &VT600-1394 mainboard / AMD XP2500 CPU / 512 MB DDR there is no post.............when switching on, the hard disk LED comes on the DVD CDRW combo drive light flashes intermittantly and there is a few weak pops from the speaker, [nothing that could be interpreted as a beep code] the keyboard indicator is lit but there are no flashes as per the normal boot sequence...... and that is all...psu/cpu fans are spinning and the ram led is lit.....PSU voltages are all reading correct levels....the motherboard is on an antistatic bed with a 3rd hard drive connected to the power only, [the hard disk is spinning ok], a pci video card and keyboard.......the minimum config possible.... i have also swapped out the ram, video card and PSU with no improvement.......it is down to the mobo or cpu i guess unless i have missed something thanks for any input
