Inspiron 3537 soo many problems

So I bought a dell inspiron 3537 5 months ago with these specs:

-Intel i5-4200U 1.6Ghz
-AMD Radeon HD 8670m 1gb
-Intel HD Family
-Windows 8 64-bit
-Seagate ST500LT012-1DG142 500gb
-4GB Ram

From the day I bought its been nothing but problems. There is a whole list of them

1) Ever since I bought it the hard drive has been making soooooo much noise I can't sleep while the laptop is on. I know it is the hard drive because it is coming from the right hand side of the laptop and I had disabled both the optical and dvd drives and the noise was still there. I have run every test that I have found, I have used bios diagnostics CLEAN, SeaTools full scan CLEAN, Speedfan's SMART test CLEAN again, have defraged it as well and nothing works. Even with headpholes on and while gaming I can hear it making noise, it's driving me crazy. And the noise happens all the time, not just when running demanding games, even when watching youtube videos or listening to music it is super loud. It's been like that from the start, but I am on the verge of losing my sanity because of this. I have set it to be idle after 20 minutes of inactivity but apparently that doesn't do anything either. The sound is like a static noise, I can't really explain it but it is very obnoxious. Sometimes it gets really high pitched as well.

2)Since the day I bought it, sleep and hibernation mode and sometimes even shut down don't work. I can't even turn off the display. The screen just goes black but it still works, the lights are on, and I can hear it working but I cant turn the display back on ever. I have to keep pressing the power button to shut down and start again. I have tried uninstalling the amd drivers and the intel drivers and install the ones from the dell site, but they are really outtdated and don't even work.

3)Another problem I had but was fixed was that my charger was not recognised but I contacted dell and they sent me a replacement one. The thing is, though, sometimes when I stop playing a game I come  back to the desktop only to see that there is no charger connected. I unplug it and plug it in again and it shows the charger for 1 sec and then it disappears. The only temporary fix I have found is removing the battery and then putting it back on (I have the battery plugged at all times because I have been terrified the charger will stop working again like before) but the problem comes back after a few days.

4)Every time I would run windows media player, my dvd tray would flash and beep for no reason. After I run an update from the dell site the beeping also happened when starting up and closing games. I had to use system restore to undo that. The only thing I have found to stop the beep when I run wmp is disabling the dvd driver from device manager (PLDS DVD+-RW DU-8A5HH). I have tried uninstalling and then scanning for hardware changes in device manager but it didn't work, I have to keep it disabled if I don't want it to beep all the time.

5)I've also had many other issues with dell updates. The first and worst was after an update that dell recommended, I restarted the computer and entered my password only to be greeted by the error message: The user can't be found or something like that. In other words I lost everything. I had to use legacy boot and reinstall windows to gain access to my computer again. Another bad update caused my startup to take much longer and the screen to be black after the welcome message for a few secs before loading my wallpaper and shortcuts and also every time I shut down my laptop the screen goes black then lights up again for a few secs and then finally shuts down.

There are no words for this, honestly buying this laptop was the worst decision I have ever made. I was so happy to have an upgrade from my old laptop but now I just want to throw this one out the window and keep the old one. I was sure I wouldnt have such issues since my dad has a dell laptop that is like 10 years old and it had no problem. Turns out that laptop works better than this one. I really need some help on this one, I wanted to contact dell but I keep waiting on the phone for hours if noone can help I can only hope they will answer sometime and send me a replacement laptop, otherwise I will stop paying for it. And before you ask my laptop is fully clean of viruses and everything, have run windows defender's as well as avira's and malwarebytes' anti-malware full scans and they all came back clean. Also run dell's full diagnostics and everything came up clean, I have no idea why everything comes up clean when something is clearly wrong with it.
