While trying to fiddle with my old Intel D915GEV motherboard, I encountered a problem. It won’t boot! No boot up post screen. This PC is really old; I got it around 2005. With a Pentium 4 CPU, it is still an interesting piece of old hardware. However the CPU did run very hot. The fan & heatsink that came with it wasn’t really fitting, and I had changed it to a proper version. However the replaced heatsink was smaller and fan top speed was slower than the wrong fit version.
A black screen, no post boot up could mean several things. Some possibilities were: the motherboard was dead, there was not enough power from the PSU (Power Supply Unit). However this unit was very old and some parts could be somewhat rusted. I pressed the CPU and RAM and removed some unneeded peripherals, and voila! It booted! So it is still alive!
