Minecraft running at 0-5 fps?

I just got a new laptop. An asus 401u that has AMD as its graphics driver. I'm not very good with computers and was wondering if anyone had any advice.

I have:
updated graphics card
run virus scans
closed extra windows down
tried using optifine mod and also MCpatcher (separately)
set all settings to tiny, no clouds, decreased particles, default texture packs etc.

last thing is that once in a blue moon, itll run at 20-30 fps on normal distance and normal difficulty, But that has only happened maybe 4-5 times ever.

Added (1). Processor: AMD E2-1800 APU with Radeon HD 7340 graphics (2 CPUs) ~1.7GHs

memory: 4096 MB RAM

anything else i should put from there?

Do yourself a favor and type in your specs. On your PC, search "dxdiag" and tell us the specs.

Try downloading Razer Game Booster. My videos I was recording and games work so much better after downloading. Technic worked at about 20-50 fps now It works at 60-100 Link: http://www.razerzone.com/...amebooster

Your memory is a bit small for Minecraft and java can't run as well. All I can say is that your graphics card isn't great and your processor and memory isn't either. My only suggestion, is if you have a windows 7 operating system, change the appearance all the fancy stuff like transparent start menus or stuff like that all off)
