So I got the PC setup and all and when I turned it on, nothing. Shut it down using the switch on the PSU and then tried turning it on and it booted into XP. Then it froze and I shut it down again with the PSU switch and now it won't display anything on the monitor when I turn it on. The monitor is good, it worked when I tried ot on my laptop and the cable is good too. I had an internal speaker already installed on the motherboard so I tried booting with no RAM (usually has 1 stick of 1 GB) and there were no beeps, removed the graphics card and still no beeps. I removed the HDD, Optical drive, Network card and front panel card reader and still no beeps. Used my multimeter to check the voltages on the PSU and I got these results :
3.3 V wire showed 3.2 V
5 V wire showed 5.2 V
12 V wire showed 12.6 to 13 V.
These results were measure with the PSU spinning the HDD so it had load. I was using an analog multimeter and I know it works correctly because I checked some 1.5 V and 9 V batteries with it and another multimeter and the results were the same. When I had the graphics card installed I could feel that the GPU was working because the heatsink was warm to the touch (has no fan, passive cooling). With everything plugged in the CPU fan works, HDD spins, I can open and close the optical drive, the GPU is working, on the front the power light works and my motherboard also ha a power light that lights up too. Could you please help me in diagnosing the problem?
