Hey guys, I'd like you to help me with a question I'm having about my PC. A few days ago I was on Youtube, the PC (described below) turned off out of nowhere, I tried to turn it on back but shutdown in 5 seconds. I tried to turn on again, but now the CPU_LED is stuck and I can not POST or even enter BIOS! PC Description: CPU: i7 870 STOCK Mobo: ASUS P7H57D-V EVO RAM: Corsair 2x4GB 1333mhz Source: XFX 550W PRO Core Edition VGA: GTX 760 Here's what I've done: -Reset BIOS either by removing the battery or by moving the jumpers -I tried my PSU on another PC, and it works perfectly -Booting the PC without memory = According to the manual, it should beep, but it didn't. -I tried my memories on another PC, it works. -I checked CPU and still warm up, dunno if it's related The most curious is that, if I turn the PC on without the 8-pin connector on the processor, the PC turns on, the LED light on the CPU goes off, but the PC shuts off shortly thereafter. If I boot PC with the 8-pin connector, it gets CPU_LED on, but if I keep the 8-pin connector and take out the CPU, it's still the same, almost as if the processor was never there at all. The manual says that if you connect the mobo without the memories, the PC should beep, but it didn't. In other forums that I researched, turning computer ON with no CPU nothing happens, does not POST (obvious) but also does not generate beep or anything, even if everything is OK. So, what might have died? Processor or motherboard? Has anyone went to something crazy like this?
