I brought this desktop computer about 2 months ago.
I was hoping i could fix it myself save sending it back cheers
You need to send it back before you void the warranty. At the very least, you need to contact the vendor and get on record you are having this problem.
My first suspect is the PSU. You could try one stick of RAM at a time. And you need to ensure the CPU fan is properly connected - but really, you risk voiding your warranty if you mess with it too much.
