PC Specs:
Intel Core i5-4460 3.2Ghz
Vengance Pro 16GB DDR3 1866Mhz
Corsair 600W Power Supply
MSI Gaming X GTX 1060 6GB
Gigabyte B85 HD3 Motherboard
Windows 10 64Bit
1TB Western Didital HDD Blue - 2 Years old
500GB SSD (Forgot manufacturer) - A few months old

The Graphics Card is a year and a half old, the Power Supply is a 2 - 3 months old, ram is 6 months old and the rest is 2 years old.

I think it's dying because sometimes when I start up my pc, the mouse lags so much it's unusable, Windows 10 is ran off my SSD as well with a few games, Grand Theft Auto V, Counter Strike Global Offensive and Garry's Mod. It takes 6 seconds or so to load into windows but as I said, the mouse lags that much it's unusable, and then it sometimes crashes. Once it crashed, I restart my pc and it's perfectly fine. It can't be ram or anything like that, makes no sense for it to be the ram. Hope you can help, thank you :)

Right now, I've got 5 tabs open on google chrome, two are youtube and one is playing music. I've got Microsoft Visual Studio 2015 open and I'm coding a game, it's running and not lagging and neither is anything else (currently). I'm using 7 - 10% of cpu usage while doing all this too. I've tried a stress test and pc crashed.
