I have windows 7, 32 bit.....
Won't matter anyway, as your running 32Bit Windows, which is LIMITED to 3GB of memory, games (NO WINDOWS, NO DRIVERS, NO ANTIVIRUS, NO ANYTHING ELSE RUNNING) need 4GB normally. You need to use Windows East Transfer (just SEARCH through the Orb in the bottom left corner) and back up to a External HDD, then reinstall with Windows 64bit edition. If your using a OEM only licensed for 32Bit, then you will need to BUY a new copy of Windows to do this.
Second a R7 240 is a VERY LOW END card NOT for gaming. It is a general purpose GPU and will suck for the games even on LOW SETTINGS. Depending on the rest of your settings of your hardware (download and run SPECCY then copy and paste the first tab here) you probably won't be able to game on your PC sufficiently.
As with the MANY OTHER POSTS HERE of people NOT having the money to PAY TO PLAY (PCs are expensive!) your BEST alternative might be to switch to console as they are cheaper and can run all the games, new titles AND even play some at 1080p High settings 60FPS (aka Like I saw on Youtube! alot of people say)
