Hello Tom's Hardware community!I'm not sure if I have to write about my problem here,sorry if this isn't the right place but yes lets move on to the problem.So today I started my PC and it worked a couple of seconds and then shut down.I thought that the windows might restarted the PC for some updates or so.But after a few minutes it didin't start and I tried pushing the start button but nothing happend.I immediately checked the power cable if it was in place but again it didin't work.I tried removing the power cable and after a few minutes to return it back but again nothing.I know something might went down but I'm not sure what probably the PSU because my motherboard has a diode which lights up green all the time and it is still green.I also noticed that when I remove the power cable for a couple of minutes and then put it back in when touched the start button lights up and even my fan which has LED lights they light up too but this is only for a second and again the computer goes dead.
My PC:
CPU:Intel Core I5 3570k
MB:Asus P8/z77 VLK
PSU:Cooler Master:700w
GPU:Sapphire Radeon HD7950 3gb OC
Ram:1x8gb Kingston Hyper X 1600 mhz
