Not what I expected. Please help

[Byzazam]

Hello guys.
This is my first time here and Im asking for a suggestion regarding my first build.
I decided 4 months ago to buld my own PC and had a buget of around 700-800 Euro. I did some research and I came up with the following :

Gigabyte Radeon R9 380 Gaming , 4 GB GDDR5, 2x256-bit
Intel Core i5 4460 3.2GHz, 84W, socket LGA1150
Corsair Vengeance 8GB DDR3, 1600MHz, dual channel, CL9
Seagate Barracuda 1 TB, SATA3 7200rpm, 64MB
EVGA 100-W1-0500-KR, 500W, 80 Plus
Gigabyte MB INTEL, B85M-D3H-A, 32 GB, Socket 1150
I didnt buy a SSD because I was out of money.
My problem is I expect...more...I can run new games on a decent level, and I knew that when I decided on the parts list, but I stil have low FPS on older games, sometimes stuck on youtube videos, extremly long booting time ( around 10 min until I can freely use it after windows loading ).
So my question is : what did I do wrong and what do I change ?

thank you for your help

You should not have a 10 minute loading time even on a standard drive.

Try a clean Windows setup, make sure your heatsink is on properly.

Your PC seems fine, the boot up time should not be 10 minutes. Do a fresh install of Windows or whatever OS you're using if you can, but otherwise run some scans for viruses and do a "UserBenchmark" test. It will tell you all of your problems usually. http://www.userbenchmark.com
