Can I change the graphics/video card for the Sony Vaio VGC-JS155J/P all in one desktop?

Like the title says, I want to play more detailed video games and I'm wondering if I can upgrade the video card of this computer. The model of this computer is the Sony VAIO VGC-JS155J/P all in one desktop.Thanks in advance to those who reply.|||the graphics are currently integrated. it may be possible if you have expansion slots (PCIe x16, AGP or PCI), but i doubt it. Call tech support and ask if there is room for addition of a graphics card. good luck.|||Yes, You can do it.
