I have two computers that developed the same exact problem yesterday. Despite both of these pcs not showing any signs of life, the usb power on both of them seems to be fully functional. This started last night with my brother's pc going out while he was gaming and now my computer is showing the same exact symptoms, despite being made of completely different components. I'm at my wit's end trying to fix these. I've tried different wall sockets, I've tried disconnecting components down to a baseline, I've tried clearing the cmos and making sure the Power button is connected right. I'm not sure what else to try.

Update. After disconnecting the power and holding the power button to ckear power from the mobo, and plugging it back in and trying to power it on, the cpu fan seems to start spinning but immediately stops.

You want to pray that it is just the PSU (Power Supply Unit). Lay the PC on its side with the side off, set another PSU on top of the one bolted in, connect the two systemboard power connectors and the video card if it needs it, then turn it on. If you are lucky, you'll get an error on the screen about no boot devices! If you do, try the other PC then go about replacing the bad PSU(s)

It did indeed turn out to be the PSUs on both. I guess there was a surge of some kind on the breaker we were on.

That's about the cheapest fix for no boot, no wheedle, no cursor there is! I'm glad you fixed it.
