Build a new system wich worked perfect for 6 hours. flashed bios to 1011 for x2 support and new video drivers. For my asus 6600. after a normal shutdown from windows i came to turn the system on the next morning and... NOTHING. nothing at all. no fan noise no boot up nothing. The green light is on. please help..I tried different startswitch but this did not help. also tried just the mb/cpu+fan/ram and videocard.nothing is overclocked.
Could be the power supply unit. Which PSU are you using?
Antec Truepower 2.0 550 watt
Found the problem it was my internal modem .... Once it was removed bootup was fine so now have to get external Modem ...
Nice to hear you have the thing up and running again.
