So the thing is these weird random shutdowns these days, whenever i regular work on my PC basically, my pc shuts down itself, first monitor goes off then gpu fan goes to 100% speed (maybe more than 100%), HDD led goes very dim, power led stays off, led inside motherboard stays on. To shut this thing down i have to forcefully cut its power source.
The main thing is my PC doesn't even starts again after a shutdown like this, when i press the power button to start it again, all the components inside cpu starts for about a second then goes off and hdd led stays on but very dim.
To start this thing i have tried a lot of things including cleaning up the mess of wires, cleaning up dust, removing and re-placing the ram, replace sata cables. At last, i thought it is my smps which has given up (bought this april 2012) but i tested it with hair pin test and it worked perfectly (connected atx green wire to any of the black ones).
The trick which worked for me is that, i removed atx connector from motherboard than pushed the power button(i know it won't start) then turned off the power and re-plugged the atx connector to its place, now my PC started like before after pressing the power button.
Now i want to ask the expects what do u think is the problem? Is it hardware related or some software incompatibility? I am asking about incompatibility because i am using windows 8 release preview since 4 months, i never had such an issue with windows 7 or any previous version of windows.
Now this problem is expanding, whenever i shutdown my PC, it is putting me on the same situation like when that random shutdown happens.
Please help me if u know anything about this error!!!!!
