After years of great service this morning I went to power up my computer and nothing happened , Well not nothing . The CD rom's lit up ( But the lights would not go out) . The power light was on the fans and the water pump were all working but nothing else happened , The HDD light was not coming on though . It was strange , I have had this happen before when I used my tech water block . It took forever to get the thing to come back on line , powering it on and off , unplugging it over and over again but then it woke up like nothing happened booted right up . Then I was playing Fallout New Vegas and the system just turned off , Out of the blue it shut down . Powered it back up play the game for about 2 hours now and every thing seems to be just fine now . Is this an indicator that my PSU is going out or is this just a random happening ?
