Thanks for the advice, hope this helps resolve this issue.

My first guess is, like Executor says, compatibility issues.

You have two different RAM modules, with different voltages. One says 1.35 volts, the other says 1.5 volts. You need to match to the original, which seems to be 1.35 volts. Not 1.5 volts. When installing RAM always try to match with the same vendor and module. And if possible, in pairs.

Regardless, your issue appears to be mismatched RAM modules.

To be safe I would get a pair so you know both modules match.

Good luck.

Glad we were able to solve your problem :)
