Re-read my previous post. Posting a more in-depth answer;
Processor: List of Intel Core i5 microprocessors - Wikipedia, the free encyclopedia
1024MegaBytes (1024MB) = 1GigaByte (1GB)
Your RAM amount (Memory:) is 8192MB, or 8GB. (1024MB x 8 = 8192MB)
A look at your motherboard not installed, and has no hardware components on it, (Not advertising for Ebay), ACER ASPIRE M3910 DESKTOP MOTHERBOARD MB.SDX07.002 MBSDX07002 S1156 H57H-AM2 | eBay

The alternate Blue and Black long slots, with the white Locking 'ears', are your RAM slots.
Right below the RAM slots is the processor socket. It is an LGA 1155 processor socket. (Socket has the contact pins, processor has the matching socket holes. There are one thousand, one hundred, fifty-five contact pins)
To the right of the processor socket is the PCI-Express x16 expansion slot. Black, with a white Locking Arm.
To the upper right of the PCI-Express x16 slot, (By the white Locking Arm), is the Southbridge chip. The Intel Core I processors do not use a Northbridge chip.
(QPI. Quick Point Interconnect ) (Nor do they use a FSB. Front Side Bus)
Processor has Solid Capacitors surrounding it. (Part of the Motherboard Voltage Regulator Circuit. They are probably Polymer solid capacitors. Regarded to be better than Electrolytic Capacitors)
Your computer IS using, (Provided you have your monitor plugged into the graphics card, and Not the motherboard), the AMD Radeon HD6450 graphics card.
(Should have caught that in the previous post. It is an HD6450, not 6540) Northern Islands (GPU family) - Wikipedia, the free encyclopedia
