My computer will not turn on
Ok, so here's the major issue. I bought a computer cpu from the brand pluto from singapore 2years back, now when I use it, when I turn it on everything lights up except the green light indicating cpu activity, but no image is shown on my monitor, white states no input detected. It is only after I press the reset button on the cpu and through trial and erromr manually shut it down and turn it on will the cpu womrk, but even after that it is prone to freezing and blue screening.it also blacks out periodicallt with the cpu running but the monitor dead I have tried everything from system restore to scanning for viruses, but to no avail. I am despkerate as I have major projects to do on it but it simply will not start.
