I use to leave my PC turned on for a long time, but ultimately I've found it blocked. The mouse just don't work and the keyboard leds are blinking and there is no HD activity. I'd like to know which log should I check, to find the problem or what should I do. I u need more details, please just make know how to give'em.
It seems a hardware error. Check your hardware before check the software. You should check the CPU fan especially, so the boxes appears totally freezed when CPU is overwarmed; next, the mobo and the RAM. If don't exist any hardware error, it will be time to check the software.
