Nice video but completely useless as far as diagnostics go.

What is the name and model of your computer. OS and RAM.

What if anything do you see on the screen. Do you hear any bleeps

If the screen is blank, there is a good chance it is the power supply. The fans spinning mean nothing.

It's a custom build I bought years ago.

RAM is 4GB 1333Mhz & OS is Windows 7 (I think, old HD I plopped in it).
Nothing comes up on the screen and no bleeps (Else you'd hear it in the video).

It only happened after I fiddled with something (It was a good few months ago, so I can't remember now).

Did the OS on this hard disk you popped in already have Windows 7 installed on it. If so it will never work. You need to install Windows on the computer it is going to run in.

If it stopped working when you fiddled with something only you know what you fiddled with. Was this in the BIOS or in Windows.

"Removed individual components and tested without"

Did you have the HDD disconnected? You don't need drives to POST & if a drive is bad, it might prevent the system from posting.

Yes I tried removing the hard drive, and no POST beep was heard.

It doesn't appear the board has a piezo speaker, do you have a case speaker connected to the board? Can't hear beep codes without one or the other.

You need to disconnect ALL drives, remove ALL cards, remove ALL RAM except one stick, unplug ALL external devices except the monitor & keyboard. If that doesn't allow the board to POST, remove the last stick of RAM & try again. It should beep like mad with no RAM installed. If you still don't get any beeps, either the board, CPU, or PSU is bad. Fans & LEDs do NOT necessarily indicate the PSU is good. I didn't see the label on the PSU in your video but I suspect it's a cheapie.

BTW, did this system ever boot? If it did, what's changed? Is the heatsink installed properly? Just a single dab of thermal paste in the center of the CPU? Like THIS?

Hi, thanks for taking the time to respond.

The board does have a speaker connected.

All drives removed
All cards removed

(There was no monitor/keyboard plugged in initially during the video, so that's removed)

1 RAM removed

Boot up, no post.
Power off, unplug power supply (Just to be safe..)
Remove RAM (No RAM in system, literally only thing plugged in is PSU and CPU and Motherboard at this point) and no POST.

System did use to boot, yes. However I decided to do some "Cable Management" to it but that seems to have screwed things up heavily.

Heatsink is installed properly yes and CPU has a fresh dob of Thermal Paste applied from a few days ago, no go. (Wouldn't matter anyway, as there would still be some sort of temporary POST before it burnt out).
