Hi, thank you from your quick and detailed reply.
I do understand much more after reading what you wrote.
So sorry, it was a typo on my behalf, i meant "uses" instead of "useless"
Ah okay, i think i shall upgrade my Ram then. And of the 2 brands, which would you say is better or recommend?
And also, is it possible to use my 4Gb DDR3L ram that i am about to replace on a different laptop? Say with a laptop that isn't of the same Specs or processor and motherboard as the Dell Vostro 5470. Or will i hear a beeping sound when i try to use it? Haha yeah, don't wanna waste a brand new 4Gb ram since there's only 1 slot.
Okay, i shall check Ccleaner out, and is there anything from the list that i shouldn't touch? Because i don't want to accidentally disable stuff that will cause problems to the running of my laptop.
Thank you once again and i await your reply

No problem, glad it helps.
Ah, I misunderstood then. No worries, as long as you understand.

Honestly I would pick up Corsair for sure, since Corsair have a better reputation than Kingston, and I myself have a few bad experiences with Kingston.
Yup, in most case you can. Usually DDR3L RAM can support standard 1.5V as well. For example look up Corsair specs detail CMSO8GX3M1C1600C11
here. This means DDR3L can be supported by all kinds of notebook / ultrabook. No need to concern on brand / processor / motherboard etc. But you have to at least make sure two basic things:
1) Laptop must be using DDR3 version, not DDR2 or DDR (most important, for obvious reason

)
2) Laptop must be supporting 1600MHz, if the laptop can only support 1066 / 1333MHz, you wont get the benefit from this DDR3L 1600MHz full performance. But you can still use this.
I just quote another interesting knowledge for low voltage RAM when comparing to standard one:
QUOTE
The difference between the two is the voltage required to run the RAM at 1600mhz. Despite 1.5v being more than acceptable, a low voltage is generally always better. It means less stress to the CPU memory controller and also allows for more headroom when overclocking.
That's the reason why I bought low voltage RAM for my desktop.
For CCleaner, you just have to remember one thing: all startup item listed here are safely disable. I can assure you that. CCleaner already filtered out all critical Windows startup apps (or Services) and listed everything else that will not affected your system much.
(I try to be more elaborate here)

Startup and Windows Services are two different things, both starts together when Windows boot up, but Services are more critical to Windows compare to Startup. CCleaner only listed Startup programs. Open msconfig for more details on the list of both.
tl;dr Just disable anything without worry. Restart to take effect. And enable back the apps if you feels you need that back.
Eg.
You disable touchpad startup apps, named ELAN. Or disable Dell Audio.
You restart, touchpad STILL CAN BE USE but may not much functionality such as using multiple touch or no multi-touch system tray indicator. Or you can still hear sounds, but cannot set any sound mode eg Orchestra, Karaoke etc.
You enable back and restart again, and its back already.
