Laptop so laggy, what to do?

I have had my laptop for a long time now and i play a lot of games on it, minecraft, Just cause, Gmod, etc. It didn't used to be so laggy but now it is running at like 10 fps. My friend says it is because i download so much things onto it but i don't think that that's the case. How can i make my laptop not so laggy, Like 30-40 fps?

Do you know this minecraft seed?

So I found this seed on chunkbase.com, and it was probably the best seed I've ever found. I remember a good amount of info on it. I think you guys will hve to use admist or something to find it, if you'de be so kind. The first digit was "-7" (note the NEGATIVE!). It had three sevens in a row, I believe in the middle of the seed ("777"). At the end I THINK was 659 or 609. It had the digits 6, 5, 3, 0, and 9 in it. (I hope this info is good of actual use! ). You should spawn in a desert. If not, a forest or plains. There should be a mesa biome around it. Not too far (few 1,000 blocks) is a mushroom island (I don't know which direction), and maybe 8,000 away somewhere is an ice spike plains biome.

Something is wrong with my Minecraft?

So my family just got our computer upgraded to a Windows 7 because our last computer was really old, so i tried downloading Minecraft on it (minecraft.msi) and i did everything you're supposed to do, going on the website and downloading it, running it, but after it finished downloading, it displayed a message on my screen, "Unable to start the Minecraft Runtime Environment. This is most likely caused by a corruption. Please try to reinstall Minecraft." I keep trying to redownload it but it keeps doing the same thing. What do i do?

I've downloaded Optifine for both 1.7.10 and 1.8.4 and neither of them seem to work or even appear on the launcher. I have installed them correctly but they just don't show up, can I get help? I've tried to uninstall the game, yet nothing seems to work.
