I'm going to try explain this the best i can. I did some cable management and fitted a new GPU cooler a couple days ago. Now the computer boots fine if i don't shut it off at the power (on standby basically). This only happens after i did cable management and gpu, computer was fine beforehand. Once i shut off the power at the socket or remove the plug then go to boot again with the power on, this happens: The pc boots for 2 seconds (monitor dosn't activate), pc shuts off. Then about 3 seconds after it boots again straight to windows and no issues? It's hardly a problem, but its one of those things that makes you worry that something isn't right in there? Anyone had similar experience, any help or advice on how to stop this?
