So my computer froze. And the power button I have has always been very finicky, sometimes it would take me many presses of the button to get my PC to turn on. So, when my computer froze today I tried the regular power button to no avail.
So I decided to flip the switch in the back to turn the computer off.
Now, when I DO get it to turn on, it lights up for a second then shuts off. And does this repeatedly.
How screwed am I guys? I'm sweating and so worried.
