Could my All-in-One computer be upgraded?

[seven_1]

This is my computer-

I'm running low 40-50 fps on my computer while playing the game CSGO, but I found that my CPU is pretty good, but I have a lousy integrated intel graphics card. I was wondering if iI could possibly replace a better graphics card into this computer, or if I have enough space to fit better one in.

I'm an extreme noob in PC. I've never disassembled a PC(especially An All-In-One) and I do not have money to buy a new PC. If there is any way to replace my graphics card from this computer, what graphics card do I change to increase my fps in CSGO?

CS: GO Minimum Requirements:

Intel CPU: Dual-Core Pentium D @ 2.4GHz
AMD CPU: Dual-Core AMD Athlon 64 X2 @ 2.0GHz

RAM: 2 GB

NVidia GPU: NVidia GTX 200 or greater
AMD GPU: AMD HD4000 or greater
Video card must be 256 MB or more and should be at least DirectX 9-compatible with support for Pixel Shader 3.0

HDD Space: 15GB

FPS Verdict: 60 - 100.

Your present system does not have space for a video card and lacks an adequate power supply to run a video card.

I suggest you buy a bare PC case to put your CPU in. An H61 Chipset is a 2011 model. You can find a motherboard that is Socket LGA 1155 on eBay.

Net:

You can't upgrade the video in an all-in-one. It is what it is.

You can buy an older used gaming PC or PC parts and make a gaming rig, but it will end up costing a few hundred dollars and you must be willing to take risk and learn to swap parts. This is an example of what you can get: (I do not know the seller or know if this is a scam other than reading the listing) $320 Intel i3-4170 3.70Ghz GTX760 8GB RAM SSD+HDD http://www.ebay.com/itm/Gaming-Desktop-Intel-i3-4170-3-70Ghz-GTX760-8GB-RAM-SSD-HDD-/172436551243?_trksid=p2141725.m3641.l6368

A new (not used) gaming PC (pre-built or you build it) costs minimum $400.
