acer aspire e1-771g-33128g1tmnii bios and GeForce 710m

Hi there.

I bought the laptop via the Internet. Overall satisfied, but is concerned that:
- Noise cooler as if working full. I thought dusty and hot - make out - clean.
- Stated in the laptop graphics card geforce 710m, but in the computer management - Device Manager can not see it. What could it be? When demounted the laptop cooler and removed, there were 2 playgrounds - one percent, and the other as I realized just graphics. It is impossible to pull out? it is soldered to the board like? The BIOS does not show anything, only information about the built-in intel HD 4000. I thought it is disabled, but there is no Advanced tab to watch (
- In the laptop has been replaced on the processor i5-3380m, it may be associated with these issues above?

Chipset intel HM77, BIOS version 2.30 (the latest official site), insydeh20 rev3.7, windows 10

Help tips, please, can we fix it?
