Recently (a week ago) My computer shut off randomly and wouldn't turn on. A couple days after that I got it to turn on but nothing shows on the monitor and the computer doesn't boot. So I'm wondering how to know what I need to replace in the computer. Thanks for any help.

How do you know it's not booting if you can't see what's being displayed? Try clearing your CMOS and if your computer has integrated graphics, disconnect your discrete graphics and use integrated instead. I don't know anything about your specs, so this is a general suggestion assuming you have both integrated and discrete graphics.

Sorry my bad. I heard that to know if it is booting or not if you press the Caps Lock key the light will light up if it booted and if it doesn't light up it's not booting. I'm using integrated graphics (no video card at the moment)
And since I don't know my specs by heart I'll look for it

Tell me if you need anything else

TR2 units are no good so I immediately suspect your power supply, but an APU would draw so little power from it that it's probably not an issue.

That makes sense I've been having problems with it (random shut offs) but never really thought about it. I don't have the CMOS jumper so I took out the battery and put it back in and it didn't work.

And what other power supplies do you recommend?

For an APU build, you don't need much at all. 300w would be more than adequate, but pricing makes it best go with ~450w. The Antec VP-450, EVGA 500B, Corsair CX430, and XFX Pro 450w are all good options around $40. I'd suggest whatever is cheapest.

That said, it's probably not the power supply that's your problem.

Ah so how do I know if it's either the motherboard or the CPU? I don't want to replace the motherboard then realize it's the CPUs fault.

There's almost no chance the CPU failed and unfortunately, a motherboard failure is very hard to diagnose. If it's turning on and running but not displaying anything, it sounds like a configuration issue that would be fixed by clearing the CMOS. Did you say you don't have the jumper? That would be a problem because there needs to be a jumper on pins one and two of the pinout.
