Hello, I have been having this problem for awhile now and have not been able to narrow down what it could be until now. My computer will All of a sudden my screen will go black, the speakers will make the usual "ERRRR, fked up" and the fans in my computer will speed up to max. Now I have checked my event logs and nothing, Ran every diagnosis I could and nothing and didn't know what to do until I saw this. Now I know the voltage is a little under than what it should be for the -12 V however I used my Psu tester on it and it says it is fine... However its always good to get a second opinion about these situations.. So would anyone know if this is why my computer will tend to crash a lot ? Or should I be searching somewhere else ?
