Bluescreen errors help!

[Slipnation]

Yesterday at around 9pm I was watching youtube videos when I suddenly got a bluescreen. I didn't mind it just updated flash player thinking that was the issue.
Before I went to bed I put the computer to sleep and today when I woke up and turned the PC on I got another bluescreen. I'm starting to get worried since I am no computer technician and I have no idea what to do from now.

What should I do, where should I start?

Check your RAM, maybe remove your sticks one by one to see if one of them is faulty.
If you have another set of RAM, replace your current one by this one to check if it works fine also.

Is there not a test or something to do so itself determines which RAM is faulty? Or do I have to do it manually?
