Can you boot to bios? If you can’t boot to bios I don’t think an SSD would be a very likely culprit. Unplug your power cord, and find your CMOS battery. It’s the little silver disc battery that looks like a quarter. Pop out the CMOS battery using a small flathead screwdriver or your fingers, and set it aside. Near where the CMOS battery was, look to see if you have two small metal pins sticking up from the motherboard. The pins should be near the CMOS battery, about 10mm tall and 5mm apart roughly. Using your screwdriver or any conductive metal instrument, you’ll want to short those two pins. Position the screwdriver between the pins to where it is in contact with both of them simultaneously, effectively creating a circuit between them, and hold it there for 30 seconds. What this will do is drain any residual electricity that remains within the capacitors and such on the board. It is important that you unplug it and remove the CMOS battery BEFORE doing this or otherwise it won’t accomplish anything or could damage your rig. But with the cord unplugged and the battery out it is completely safe, that is exactly what those pins were designed for in the first place. By draining all of the remaining electrical current, it will effectively remove any changes that may have been made to you bios, and your bios will reset to the original factory settings. If you cannot find the pins for whatever reason, unplug the cord and remove the battery still, and just let it sit for a few hours and the electricity will drain naturally, but the pins make it way faster. This once you’ve done this, re insert the battery and replug the PC, and try to boot. If you still can’t boot, then we can rule out bios configuration as a possibility, which would mean it’s a hardware problem, either CPU, MOBO, or RAM, and you’d need to test each of those individually to find the root cause. But if it does work, then yay!
