Laptop just shat the bed? BSOD freezes on startup, black screen, etc

[Rat3d ///M]

I have an HP Pavilion laptop about 3 years old. no issues with it until now.

Started it yesterday and connected to WiFi. All was well but when I opened the internet I noticed some lines flickered on the screen and it froze. I turned it off via the power button and restarted it only to find that it now won't load windows. it will either:

a. give me a blank screen and not do anything when I turn it on (it has power)

b. give me a bsod with a memory_managent error (this only happened once or twice)

c. tell me that windows failed to load and give me restore or recovery options.

d. get to the windows login screen then flicker some lines on the screen and freeze when I try to login

90% of the time it's a but c and d has happened a few times. I did manage to boot in safe mode and it started just fine. Now the last 10 or so times I turned it on a has been happening. seems to be dead completely now.

Any ideas what I can do? I'm guessing bad ram. I was able to do a system restore which didnt fix the issue. it's hard doing anything as far as diagnosing because it won't even load bios now. I am really hoping to fix this and to do it for cheap because I have lots of bmw programs on my laptop that are a huge PITA to setup and I hate to lose them all.

I need to also add I don't know a whole lot about computers.
