I'm having issues with very slow POST times (pre BIOS) screen, it can take almost 2 minutes or more to even get to the BIOS screen. It loads the OS from the SSD in 20-30 seconds after that which I think is a normal time. I only have my keyboard, mouse and display plugged in on startup. Keyboard and Mouse are on the recommended ports (top left) according to the Mobo manual.

I've played around with my BIOS settings, disabling everything I thought was not necessary(Legacy USB, Parallel I/O, HPET, Legacy USB support, etc). I verified the Boot order lists Windows Bootloader on my SSD first. I haven't changed any components from stock settings. I've also enabled MSI Fast Boost and GoToBios, disabled full screen BIOS splash and yet nothing has changed. After all this I have reset the BIOS settings to default inside my BIOS and have done a clean install of windows and before loading any drivers that windows doesn't load or find on it's own the POST time is still two minutes or more.

Looking at the MOBO debug LED lights I can see that the CPU light is on for 1 sec, DRAM for 1 sec and then at least a minute or more of no lights followed by the VGA light being on for 45 seconds - 1 min approximately.

When building the PC I made the mistake of putting a bit too much thermal paste on. I realized my mistake before ever powering it on and I cleaned of the excess from my cpu and cooler but a very tiny amount slipped onto the socket (3-4 pins) . I spent hours cleaning it with q-tips and (90%) rubbing alcohol and then left it overnight. There were no issues booting up but could this be related to my very slow POST / Boot times?

I took out my GPU to see if I could boot faster from onboard graphics but the NVIDIA drivers were still there and for some reason the on board HDMI did not detect the display. I'm going to try booting up with no SSD, HDD, no USBs and just one stick of RAM in the DIMM 2 slot.

Thanks again for reading and any ideas you can come up with.
