ASUS U31F won't boot after Memory Upgrade

Hi!

I have a Asus U31F with 2x2GB PC3-10600S, i was working perfectly since I tried to upgrade it's RAM with 2 modules (same specs but diferent brand) 2x8GB PC3-10600.

After that, laptop wont boot, neither with new modules or old ones. All of them works perfect in another laptop and i tried each one in each slot and wont boot to.

Exactly, what it does its when power button is pressed, light come on, vent start and after 2 sec, shut down and tries to start again.

Any idea?

Thanks

 

The behaviour you are seeing is because the BIOS can't find the RAM and load itself. I wonder if the RAM isn't properly seated.

Try again, first with one of the original modules, pushing the module more firmly into the slot at an angle of about 45 degrees before pushing down the free edge to latch it into place. If the first module doesn't work then try the second one. Once you have success with the original modules then try again with the new ones.

There's also the possibility that you had a static electricity problem which has zapped the modules. Good practice is to make sure you ground yourelf before touching any electronic components.

As John has stated, have you tried reseatting the RAM? Also does it boot with your original 4 GB set?

 

Yes, I've tried with original 4GB set, and lots of times pulling it out and inserting it again, with caution, and same results...

Any other idea? Maybe static electricity have done anything, but not to the module but yes to the mainboard.

 

Did you remove the AC power and the battery before you pulled the RAM out?

I don't think the 2x 8GB modules would work on your Arrandale platform either way, but since all sticks are working in other systems, it sounds like you killed the M/B.

 

Of course I did! And they are modules of 4GB, total 8GB (supported by this mobo).

 

Just in case the system has got confused over the RAM changes I'd try disconnecting the mains power, removing the battery, removing the CMOS battery, holding down the power button for a minute and then leaving the computer overnight. Then put in some RAM and try again.

This shouldn't be necessary, but strange things sometimes happen.

John mentioned what I was going to suggest next.

And just because a M/B supports 8GB total does not mean it can support a single module or more of the same capacity.
