I just got an Acer Aspire 5552. It's a fairly basic thing. I have an Athlon II P-340 dual core chip, an ATI Mobility Radeon HD4200 and 4 GB of DDR3 RAM in it. I know I can upgrade the hard drive, but I can't seem to find info on the Acer website if I can upgrade the CPU, RAM or graphics. Any ideas? I am in no rush to do this, but since this will be my only machine I'd like to know that. Thanks.
