I hope this isn't a tough one to figure out. I turned my computer off the other night, and returned the next day. When I pushed the power button, the light doesn't come on anymore indicating power, but i hear the fans, dvd drive, and HDD all power up, but nothing shows on the screen. The motherboard doesn't have a power LED so I can't really tell if its getting power there. I have changed the PSU and still the same issue. Is it possible the case switch has gone bad? Would that cause the symptoms? Also it seems as if the fans are spinning at a higher RPM then normal. I have also reset the bios by removing the CMOS batt, and tried with a different monitor. Any ideas would really be appreciated. Thanks!!
