Can anyone please tell me i need to know there rep for each answers

Nope. With specs like that, it's best to use a less resource-intensive operating system like a Linux distro to get better performance.

I believe its possible, well its possible on some APU E series(not too sure about this one). Would i recommend it? No.

First of all im assuming you've got a Laptop and i would n't overclock on a laptop unless it was built to fully support overclocking. If you did the temperatures would rise quite a lot also you have no cooling options and tbh you wouldn't see much of a difference.

The PC is very outdated and if you wanted to game(which im assuming you do) I'd advise to save up some pocket money and get a decent budget together and request a Gaming PC Build in the PC Building Section in which me and other members will be happy to put together a build for you.

Also you wouldn't be able to upgrade your current CPU as Microprocessors such as yours on soldered onto the motherboard.

i just had a quick look around and someone had managed to get the same CPU as yours to 2.3ghz on the stock voltage.

although the idle temperature was around 65'C and he said that he had the laptop permanently mounted up higher for better air flow.

to be honest i don't think i would bother, even though it will get you a big boost in performance.

the decision is yours:)

hope this helps

If you want to keep your computer I would say no.

It may be possible but its not a good idea
