New computer - horrible performance?

[calin.alecsandru]

Alright so this is my first time building a PC. Here are my specs:
Intel I3-8100, MSI B360 Mortar, MSI Gtx 1060 3Gb GamingX, TeamGroup 8gb Ram 2400Mhz, Kingston A400 480Gb SSD and Corsair VS650 (2018) Gold+ PSU

My issue is this: I'm getting horrible performances. In everything.
My real boot time is around 30 seconds, and when I check in Task Manager, it says the BIOS' boot time is 11-12 seconds, while my old pc which is trash by today's standards, had 3 seconds max BIOS boot time. My internet speed is horrible. If i download a file, another download at the same time will be impossible and I'm also using an Ethernet cable and my ISP has a 1Gb/s broadband. (In speedtest.net, I get 300mb/s download).
Alt-tabing from game to desktop takes much longer than on my old pc, it takes around 3 seconds, and also the overall general smoothness of the desktop is just....bad.
If I'm installing something, everything becomes 3x slower, and even trying to open another program becomes a problem. I'm constantly getting "Not responding" in system folders/programs.
Games/programs load not much, but a bit slower than on my old pc, which I don't think is normal.
Also games. I have 10-20 fps less than the benchmarks I see on youtube, I could live with this, but the main problem is the stuttering. In singleplayer games I see it less, but in multiplayer games, man does it not stutter. I have framedrops, spikes, freezing every 5-10 seconds in multiplayer games.
Any help please? 🙁

I assume you did a new or clean install Windows? Which Windows version are you running?

I'll be honest, it's not a genuine windows, but it's the latest nonetheless. Windows 10 pro x64 architecture and forced windows update many times until it stopped finding any new updates. Yes, it was a clean i stall, as the ssd was new.

Hmm. The fact it's not genuine Windows could be a trouble point but, then again, perhaps not. Are all the drivers and your mobo BIOS up to date?

 

[calin.alecsandru]

Bios driver idk. The others, yes, except for the Intel HD graphics, which i wasnt able to install..

 

[SkyBill40]

It's worth checking to see if your mobo has the most up to date BIOS. Also, make sure all your other drivers are also to date.

All you can do is test ram using memtest, check temps and test your SSD.

Transfering an os from different hardware is never a good idea. Chipsets and software do clash bogging the os.

Concerning os not genuine i can only imagine it being pirated and who knows what is done to compromise security and performance. Because of this, its difficult to create a foundation here since your hardware is good enough.
