I have a Acer Veriton M410 and if I try and add additional memory the PC will not boot, just beeps. I tried every combination of ram with the same negative results. The system came with two sticks of 512 meg ram. The dealer swears I have the right ram. I took out my original ram and tried two 1gig sticks in four different slots. I put my original sticks back in and it works fine. Can it be a bios issue? I have swapped out ram for many a year and never had this problem. Need help with this one. Thanks.

This usually happens when the laptop is not able to take more then a certain amount of memory, as the system BIOS does not support higher. By saying ACPI as the blue screen, that tells me that the power subsystem does not 'like' having more then 512MB of RAM. I am 95% sure this is your BIOS because of that information. Check and see if you can find a BIOS upgrade for your computer model, and that might fix the issue, if an update is available.

Good luck. Window will only recognize 3.2 gigs if yours is a 32 bit system. Acer tech is not existent as far as I can tell.

i had same problem with mine, i have the acer aspire ast180-ud360a, dont put the same memory next to each other, u have to stagger it, so it looks like

------------> [1gb] [512mb] [1gb] [512mb] <--- correct setup

and not like

------------> [1gb][1gb][512mb][512mb] <--- incorrect setup

SOURCE: Incorrect RAM reported on BIOS

4GB RAM requires a 64 bit compatible processor AND Operating System to be able to access
addresses in memory that exceed the 32 bit assress space.

I'm not familiar with the motherboard that you are using but simply expanding RAM isn't enough if your
system isn't 64 bit compliant. Assuming it is, then ensure that you are using a 64 bit version of Windows 7 opposed to a 32 bit release candidate.
