Pox. Got 2 computers linked very neatly so that I only need one monitor, keyboard and mouse. One powerful computer - other not so. Main computer suddenly gave up the ghost. Ok, fair enough lets check the power first. Mmmm - light showing on mainboard but a funny crackle when I switch the power on. Disconnect everything and still the same = power supply. Use the low powered computer to log onto website and carry out some work etc. Get and itch to play DAOC. Logs on but the low spec computer ain't upto the job. Takes out powersupply from low spec and shoves it in high spec. Great working a treat. Logs into game and bang - power supply gives up. Checked the internal fuse and it had blown. Resoldering a new one in don't fix it. Something is drawing a huge number of watts. How can I check on which component is doing this? I suspect the hard-drive.
