Hi there, I recently installed 16 GB of additional RAM. Since then, sometimes my computer starts quite normally but sometimes it won't start anymore: When I push the power button, I hear the vans starting to work but after 1 sec or so it suddenly all stops. Then the computer will start countless attempts to restart but it will fail all the time. When I switch off the main power and try again after a short pause, I get to a screen where I have to reset or edit BIOS settings or load the "lask known good configuration" (press [F1], [F2] or [Alt] + [l]) anyways, I'll end up in the BIOS settings. Since there seems nothing to change, I press [Esc] and leave, wich will cause the computer to restart once again and either start to work normally or get into the endless reboot loop, again. I've read about how the power adapter could cause such trouble or the additional RAM might be defect; but once the computer runs it will also run "under load". I can use the currently 32 GB of RAM and the computer will run just fine with high CPU usage and all. Hence, I wondered how the RAM or power adapter could be the issue when both seem to work at least some times.
