Ok i had a thread with power supply maybe. I unhooked everything and it still would stay on for 5 second then turn back off. If i can the memory stick out and turn it on it will stay on but beep i know the beep means that there is no memory. But why would it stay on with no memory but turn right of if it has something connected to it. I also tryed each device and try to run with it. With just the cd drive it turns off, with the harddrive same thing.

Acknowledging the troubleshooting carried out earlier by and the suggestion from , the following is a concise, practical checklist to confirm whether the fault is the CPU or the motherboard and what to try next. Steps are ordered so you do the cheapest, safest checks first.

  • Visual inspection first: look for bulging or leaking electrolytic capacitors, burn marks, cracked solder joints, or damaged components around the CPU VRM area. Use a bright light and a magnifier. Visible damage points strongly toward the motherboard.

  • Inspect the CPU/socket area: for LGA boards check the pins in the socket; for PGA CPUs check the CPU pins. Bent, crushed, or missing pins can stop a system from booting and are usually a motherboard- or CPU-pin issue rather than PSU or drives.

  • Use board diagnostics: if the board has onboard debug LEDs or a POST-code header, capture the code. A POST card in a PCI/PCIe slot is also helpful. Those codes narrow down whether initialization fails before or after CPU handoff.

  • Isolate with known-good parts: if possible, test the CPU in a known-working compatible board or test the board with a known-working, compatible CPU. Confirm BIOS compatibility first — some boards need a BIOS update for newer CPUs.

  • Reseat the cooler and reapply thermal paste: a poorly mounted cooler or crushed retention bracket can cause immediate failures. Check the cooler mounting and the CPU for thermal damage.

  • When to replace or repair: visible board damage, bad VRMs, or many failed components usually means replace the motherboard. Bent socket pins or catastrophically failed CPUs often require board/CPU replacement or professional repair.

Take ESD precautions while handling parts. If data is the priority, remove the drive and attach it to another PC or USB adapter before further destructive testing. If still under warranty or unsure, a local repair shop can perform the component swaps and POST diagnostics safely.
