This morning, my computer wouldn't boot and a red led next to CPU is glowing on my motherboard. When I boot, my screen will say power saving mode and no activity after that. I tried to boot without ram and same problem. All my fans are turning on and I rechecked all of my connectors. Can anyone help please :(

Sadly this didn't change anything. I also tried without any ram sticks connected, and nothing changed. Do you think it's more likely to be a motherboard/ psu/CPU problem?
