Alright, a little bit a new's
After a few hour's of working on it, we thought it was the video card that was broken, but after a few looks, it was the processor, and it was completely dead.
But, there's really good news.
My granddad managed to contact a friend, who's computer he was selling/giving to him, which is more faster then his current one(More faster than mine), so, when I come back on holiday, we're seeing if he can give the computer to my granddad, I get my granddad's computer (Really good, and for free(I think ;c), this computer can run games like Far Cry 3 etc and has like 250gig+ hard drive space with I believe 4 gig's of RAM) and I think we might sell my current old computer to someone and get a bit of money off of it, although I doubt we'll get any.
I don't think you can put just any random stick of ram in your motherboard :|
No, we had a look to see what could fit and match the requirements of the motherboard to put in the computer, I wouldn't go around and forcing them in and willingly hope they worked.
Make new computer from scratch, use the RAM?
No, it's a old computer that we'd decided just to put a bit more RAM in it, but went HORRIBLY wrong.
Your cheapest option is either get a new hard drive or get an external hard drive.
I was thinking about this, but then again, I just didn't want to go through the hassle of putting in a new hard drive, and maybe loving up my laptop(Which I've done on this occasion, silly me).
I won't be working on my computer tomorrow because I'm off on a cruise around Spain. <3
