Hello all This is as much a question to confirm my fear as to ask for any alternative suggestions. Build is an i7 920 on an Asus P6tse mobo, BeQuiet 900w modular psu (op I know but a warranty replacement), Gigabyte GTX 970, 3x4gb rip jaws, optical drive, an ssd and spinner HD in an Antec 300. The machine froze (I stupidly switched some audio plugs, which always has that result) and decided to turn it off by holding down the case power switch (not the first time I've done this). It turned off but now won't restart either using the case switch or the mobo integrated power switch. However, everything attached (including the Corsair H50, the fan speed of which continues to slow to normal after its original max speed burst) appears to power up when I paper clip the psu. I've done all the same with RAM in/removed and no difference. I've tried to discharge any static using the power lead/power button route. My fear is that I've damaged the mobo and will need to replace it. Any thoughts or suggestions would be very welcome. Thanks in advance.
