My PC (i7 6700 + 1050TI) pulls ~100W from the wall in normal use.  So for 4 hours you need a 400Wh battery. This does not include screen so let's round up to say 500Wh.
 
A quick google for a 500Wh portable UPS: https://lithiumbatterycompany.com/product/500wh-portable-lithium-ups-power-supply/
According to the specs this is 7.9LB (3.6KG)

you just saved my day man had this problem for a while now

-Have you ever cleaned the drive/OS? Use CCleaner to clean up files and fix any registry issues.
-You probably also have a lot more startup services and programs than you did at first, clean house and disable programs you don't want to startup.
-Have you run a scan (like MWbytes) to be sure it's not infected.
-Check the drive health with something like CrystalDiskInfo and make sure you're not running out of viable sectors (2yrs old shouldn't be an issue unless you're doing some crazy constant writing or bought a really crappy drive, but it's worth checking).
 
-Best option: Ignore everything I said above and re-install Windows from scratch. A fresh copy is a clean slate. If for some reason that doesn't fix it then you know it's a hardware issue.
