Envy 810-150Se Ram/Bootup Issues

ENVY Phoenix Desktop
Microsoft Windows 10 (64-bit)

Computer is locking up occasionally with high speed fan. Force shutdown and it will sometimes start up with a normal power on. Other times I need to remove RAM, reinsert and it will power up fine. So I began to examine replacing RAM as an option. But when I go through system checks it reports all RAM as okay, so I am not sure if the RAM or motherboard are to blame.

 

But in the process of researching, I noticed that the specs on the machine say there are 4 DIMM slots. I can only find two. When I remove both DIMMs I see 4GB of RAM. With both DIMMs installed I have 20GB of RAM. With one DIMM it is 12 GB of RAM.

 

Now to the questions. Are there RAM slots hidden somewhere on the motherboard beyond my bifocal viewing range?:Glasses: It is a Pegatron. Computer SKU is E3W48AV#ABA.

 

Is there a way to test the RAM and/or motherboard to determine the cause of the lockup issue?

Hi

 

I can't see the picture you posted.

But to get 20 GB of memory that is probably 2 x 8 GB and also 2 x 2GB.

Equally the 12 GB is 1 x 8 GB and still 2x 2GB in the first pair of slots.

The board doesn't look like your diagram. I only have two slots visible. Will try posting the image again. This is upside down.IMG_2225.jpg

Hi

 

Yes it does seem to match. 

So you have added 16 gig of RAM that may not match the existing 4 gig installed, either by speed or voltage.

This a bit of your piccy.  Try a vanity/dental mirror to view hidden corners.

The blue  bit is your MEM Slot.

I see the additional slots hidden by the big red cooling fan. Thanks. 

Any ideas on how to zero in on cause of lockups?

FYI all of the RAM is factory installed and the issue just started a few days ago. The computer is 2+ yrs old.

Hi

 

Nope.

I would gather information first.

Piriform Speccy and MemTest/MEMTest 86.

 

Then if a module is out of sync.....
