Recently my computer got a random BSoD while I was abiut to post something on the forums. After the restart, I tried turning my computer back on, but it does nothing. I hear three beeps, fans are running, and nothing appears on the monitor. On occasion, it actually turns on but only works for at least 3 hours until it shuts down again and I can't turn it on. I haven't installed any new software/drivers recently.
I'm not much of a computer person. This is a custom build someone gave to me and it's been working for 3-4 months.
