My HP Desktop powered off overnight and now I can't turn it back on at all. When pressing the power button, the LED light flashes for a second and then goes off. The computer won't start at all. I'm out of warranty and I don't want to throw out a perfectly fine computer if the problem can be easily fixed.
Any ideas?

Hi @User38583
Welcome to the HP Forum.
You have a hardware problem if you see and hear no activity other than a momentarily flashing LED when you depress the power button. It is very difficult to troubleshoot a hardware problem in a Forum.
It may be best to have a local PC Tech take a look.
Any component connected to the MB or external device connected to the PC could cause this issue.
You have to methodically reduce the PC to a minimum config. Eventually you will be trying to start the PC using only the CPU, one stick of RAM, one at a time, in each memory slot, and a monitor.
It looks like you have Intel CPU integrated graphics so you don't have a discrete graphics card to check.
You may also have to swap in, known good, replacement components.
A PC Tech would have the required components.
