Weird problem when adding ram to computer

[Guest]

I bought an Acer Aspire 5720Z a few years ago. It came with Vista and a 250 gig HD and 1X1 2 meg ram. I upgraded last year to a 500 gig HD and Win 7 32 bit. Now I bought 2X2 meg ram and when I installed it the Bios recognised it but windows wont load. It says there is a software or hardware change and wants to try to fix it, but can't. I put the old ram back and everything functions normally. What could be wrong.

You can't use the 2x2GB RAM, because Aspire 5720Z only support up to 2GB RAM total like you have. You should return the RAM if you can.

Your Aspire 5720Z System Specs
Memory Type: DDR2 PC2-5300, DDR2 (non-ECC)
Maximum Memory: 2GB
Slots: 2

That is strange because the bios sees 4 gig ram. Does the bios need to be updated to allow windows to load?

Update the bios don't help. The BIOS selects candidate boot devices using information collected by POST (Power-on self-test), and your MB only support 2GB RAM. So you can see the 4GB RAM in the BIOS, but it don't mean the PC can boot, that why you get the message "a software or hardware change and wants to try to fix it".

OK now I understand. Thank you.

Staples has an Acer 8 gig/750 gig core i3 touch screen/win 8 for $699. Maybe that's next.
