I tried unplugging the cable for a min. It didn't work.
I also tried unplugging the main power lead and than the power to my HDDs and DVD drives. That also didn't work.
I looked at the power cables inside the case they all look ok, connected well.
Thing is I left my PC to work overnight. I doubt cables are loose or anything like that cause the PC has been in that position for like 5-6 months. Ironically the last time I opened it was to replace the power supply. So the PSU in my PC is like 6 months old. I'd hate to think it failed so fast.
But when I push the power button on my PC nothing happens, the fan doesn't start up on the PSU, nothing makes any noise at all.
But like I said a little red light on the main board is on, when the main power lead is plugged in.
It was working fine yesterday. I was sitting on it at like 1.30 am, I left it overnight, I woke up at about 4 am it was dead.
If anyone thinks if It could be anything else other than the PSU please write in, cause my PC is from early 2005, and a PSU cost like 25 $. I'll gladly spend the money if it fixes the problem cause I really depend on this PC for college.
PS: SeÃ¡n thanks for the advice.
