Help my friend

My friend really needs a new pc. We are playing games on daily bases but he can't menage to run our favorite game "Counter-Strike". Everytime we play his games crashes and keep crashing when he runs it again, and we end up losing then and he gets very sad. I would love to make him happy and get him a new pc. Firstly you should donate to someone who realy needs it for more important stuff but if you feel like it, you can help us out. Thank you!
