Have searched the forums and got some ideas but...My son's Maxdata pc with an Asus motherboard just stopped working. I have replaced the PSU but the old PSU passed the paper clip test when I got it out (as does the new one!). Where next? How do you test the on/ off button on the comp - and I have also read a dead CMOS battery might be the problem- is that true? Memory and graphics cards appear to be seated fine. What to do next please!
Bumpkin: nothing- fan on power supply not turning , nothing. Paper clip test (sorry Wiz-King!) proves psu is ok as fan does turn then. Fruit Bat: thanks, will try your suggestions tonight. Thank you all.
What are you doing Exactly with a paper clip? as above only real way to test a PSU is with it connected to the Motherboard and using a Multimeter to back probe the pins for volts, that means setting Volts on meter to 20v DC Black probe to frame of PC and red into back of each pin
Pin Volt Colours

PSU are Power Switching ie they need to have a correct load on them to test, anything above and beyond can blow the PSU EVEN a NEW ONE
