New to the group and building in general.
Installed a new air cooler and now I get no boot. Just cycling between 00 and 15 with the memOK light flashing.
Cleared/reset CMOS (both battery and jumper method)
Tried all dimm slots one at a time with each stick of ram. Was also functioning fine before hand, and I've done this trouble shoot method with other ram I have available.
Have done tried a basic boot with just CPU and ram, no GPU.
Any idea of what I should do next?
Remove the CPU cooler. Take out the processor from the socket and observe if any pins are bent (highly doubtful). Check the pins on the hardware component. Install carefully the processor and the cooler. Code 00 means "not used". This probably has to do something with initializing the CPU but I could be mistaken.
