Hello, whenever I try to launch FTB on the launcher on ANY modpack it just lags like hell.. If I try to put mods by hand into the minecraft folder without the launcher it works just fine. Before this happened, it worked fine on the launcher. Does anyone know what might cause the problem?

My pc specs:
AMD FX 6350
MSI Radeon 7870
ASUS M597L
8 GB RAM 1600 mHz

No idea, try a fresh launcher reinstall maybe by uninstalling it and redownloading?

I have done that a couple of times.. Didn't work at all.
Btw, I have Windows 8 too, does it affect it?

The weird thing that your saying it's worked and all the sudden it's doesn't. All I can suggest is try to remember what you did just before it's started to act like that.

RAM allocations?
One install of 64bit java?

I have allocated 3 gb of ram, I do have 64 bit java.
