Question about System Power Supplies
Hi, my advent computer will not switch on anymore... i've checked cables fuses etc and changed the power supply but this did not help, any assistance will be greatly appreciated! thanks
More than likely nothing to do with the motherboard.
I have the Thermaltake w0049. and for the money paid is poor quality.
This model and I would guess other models by Thermaltake go belly up if subjected to voltage spikes ie lightening strikes (they are not well protected)
Remove all the leads to your motherboard and join together the single green wire (power select) to any one of the adjacent black leads (ground).
Any atx supply, if connected to mains voltage will not operate at all unless if has some form of load on it. if you do the shunt as suggested(use a paper clip) the fans should spin and you should be able to measure the voltages between ground and the relevant pins.
If you can, plug in a hdd to one of the plugs to give it some kind of load. if you do not know which voltage pins are which on your 20/24 pin connector , then search google for "atx pinout"

SOURCE: computer doesn't switch on!
The troubleshooting techniques you might try is swapping them out with another monitor and keyboard. If they work then you know its the monitor and keyboard if they don't work then the motherboard is bad. The ports for the keyboard and monitor are integrated into the motherboard. So you can't fix the ports, the whole motherboard has to be replaced.
