I disassembled my PC to clean it and replace the case because the old one was damaged. It comes with a 6600k, MSI Tomahawk Z270, TridentZ RGB 16 GB, 3200MHz, and an ASUS ROG Strix OC 2060. After reassembly, I changed the thermal paste and added more fans, but the system still won’t spin and the screen goes black. It got stuck in a boot loop initially, then it booted after removing RAM, though there’s no post. The DRAM and CPU debug lights are flickering unpredictably. I’ve tried different cables and connections, but everything seems fine on the front panel. This machine worked perfectly before I made these changes—I have no idea what might be causing the issue now.

The top LED shows the CPU status while the bottom LED indicates the DRAM status during flashing. A change in either signal means a failure or detection issue.
