BSOD when using 2 sticks of RAM, OK when using 1 (1x8GB)

[Jake_111]

It all started when my laptop froze and crashed to a BSOD. The error messages vary between memory, driver, and other random errors which threw me off. I ran memtest on both sticks including a spare (all same model) and all three check out good. I have tried using a stick in both DIMMs and the computer operates normally using both. It only crashes when I use two.

I updated the BIOS and the chipset drivers and this didn't remedy the issue. Rather, after updating, the computer can now boot using two sticks, but the keyboard and mouse will not function and it appears the video drivers are also not operating due to the low resolution that appears on my desktop.

I checked the power supply with a multimeter and it showed ~40v coming through although the correct output should be 19.5v. This is obviously not good and I will be replacing it soon, but how does this relate to the issues I've been having? Could this be the cause of all my errors and is there something else that might be failing or has failed? Also the OS is on a 128GB SSD which checked out good using that nifty memory tester program (crystal something or another?). I re-installed windows already so I forgot the name.

Did this begin after adding the 2nd stick to the system?

The system always had 2 sticks. I only removed them to troubleshoot the BSOD I kept getting. both original sticks tested ok with memtest and even my spare (all 3 are the same make/model).

Whoops, I just realized I posted this in the wrong forum. I must have been googling some possible solutions and just posted a new topic from a thread I was reading. If a moderator wants to close this, that's fine. I'm gonna go try this in memory.
