My computer just could not power on one day but the power light on MB is on. I have tried resetting CMOS and replacing the battery. I suspect it might be the PSU problem, therefore I tested the PSU powered on by a paperclip with a multimeter. Here is the result.
Yellow : 12.17V Red : 5.09V Orange : 3.38V Blue : -11.6V
Green and grey wire : 2.96V
I think the results of blue and black wire and green and grey wire are abnormal. The former one should be -12V and the later one should be above 5V. Could these two abnormal results prevent my computer from booting?
