Question Computer starts up fine but won't boot

[robert234]

Hello helpers. I just built a new system and went into my old one for the graphics card. While there I noticed how awful the cables looked compared to the new case.
I thought to clean it up some. Removed the cooler and reapplied the thermal paste from an Intel core i5-2500k on a P8 Z68-V Pro motherboard that worked for years perfectly . It then failed to go into the bios.
I see the led dram light stay on then reboot and stay on. I tried the mem ok button but nothing changes. I also notice the cpu led flashes once every new start.
Tried everything I can think of. Removed the board, rerouted the cables, and did the remove battery thing. Messed around with swapping the memory in different slots.
I would love some ideas where to go next.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Include the age of the PSU, apart from it's make and model.

Remove the sticks of ram for your build until you're left with only one. Try one stick in the first slot(mentioned in motherboard manual) and see if the same happens with all sticks in th same slot.
