Windows crashed from unexpected error while playing League of Legends

Windows crashed while playing League of Legends no BSOD

Hello, while i was playing League of Legends a couple hours ago my monitor froze and i got an unexpected crash on my computer. A screen popped up saying "windows has crashed from an unexpected error, if this is the first time you have seen this please restart your computer". I restarted my computer as i was informed to and when it turned on again i go to a system restore screen to restore my computer to an earlier date. The monitor froze on this screen and i had to restart my computer again. After restarting my computer for the second time it kept on turning off and flashing a yellow light while beeping. About an hour later i turned on my computer and it was working fine. I am afraid of this happening again and i don't know what caused the crash, i am not the most computer savvy person but if you could help me out and see what might have caused this crash and give me instructions on what to do it would be very much appreciated. The computer is about 10 months old and it is a Windows 7 Home Premium 64bit.

Where was the beeping coming from? Where was this yellow light?

Can you also upload a report

my pc has a yellow light on top of it when asleep and a blue light when it is active, the beeping was coming from my pc and the the light was flashing yellow i tried to upload a BSOD report but when i clicked grab all i got an error pop up

I actually got the SF_diagnostic tool to work (i forgot to run it as administrator) Here is the attachment file

Do you remember the pattern of the beeping? like 4 short beeps or 1 short 1 long?

You had one BSOD and it was memory corruption. I would like you to run a memory test
