Stuck at "Starting Windows"!

[versaceflexx]

Hey there, dear community
So this problem started 3-4 days ago and i'm just sitting here all day trying to fix this issue, but no hope.
Sometimes it gets past the "Starting Windows" but when its starting up, 2-3 mins later, the laptop freezes (cant even move the mouse or caps lock)
I CAN GET INTO SAFE MODE THOUGH
Oh and it's just overheating sometimes where it turns off suddenly, just started 3-4 days ago as well
I didn't install any new software and this just happened out of nowhere

So here's what i tried so far

• 
  System Restoring to an earlier point but it says failed to system restore
  
  Going into recovery mode and running a repair, it also shows an error when it's done scanning
  
  Running CMD from recovery mode and trying to fix to the GRUB loader using fixmbr(because i uninstalled kali linux 5 days ago and i thought that what caused the problem but it turned out not to be the case)
  
  Updated the BIOS, no hope
  
  Reset the BIOS to factory settings, also no hope
  
  Got into safe mode, installed an antispyware program, installed AVG, and CCleaner, and MALWAREbytes, scanned for malware and spywares, there were some trojans, i removed those, still no hope..
  
  Got into safe mode, disabled all startups and services (except the microsoft services)... no hope
  
  Tried doing a clean boot, no hope
  
  Partially disassembled the laptop and the keyboard, tried to clean the fan (not completely though) and no hope
  
  Removed all USBS while booting, no hope
  
  Did a hard reset, no hope
  
  Did a chkdsk scan, no hope
  
  

Brand: HP ProBook 4730s
6GB ram
Windows 7 Ultimate
Laptop age: 3-4 years


Some of my assumptions that this is happening is cause of:

Overheating
Updated my Windows (i never usually update cause ik it causes issues)
Having no antivirus (only malwarebytes)
I'm sure its not cause of the HDD
Maybe i have to reinstall windows all over again?

Ill not give up, or if i did, id take it to a repair store but most of these stores just tell me its cause of the motherboard when they dont even know what they're doing!

Try to reinstall Windows, thats your only hope. But Did you upgrade your ram by yourself or?Buy Extra ventilation or clean it bcs of that it heats up.
