What's your budget?
Also check what your Power supply is.

My budget is around €140.
But where can I check my power supply?

You have too look inside your PC really. Tell us what the Voltage is (eg. 500w) and preferably the brand.

Maybe a dumb question but how do I open my pc?

Ah.. You should be able to find some screws on the back of the pc? (the side the power cable goes into.) Your best bet is to look up online and google it. If you are newing to messing with the inside of your computer it may be best to find someone you know who knows how to or if you are confident do it yourself.

If it is a pc you bought in a store it may be a pain to open whereas custom PC cases are made to be opened up regularly. Im not really the best one to help you on that one im afraid.

EDIT: If you have the model number of your computer on the box it came with? Or a link to the website you bought it from etc you should be able to read up what the power supply is without opening it.?
