My desktop hard drive seems to be failing

I’m getting memory errors, it struggles to load up my computer sometimes, and occasionally my browser and stuff I have open in general will crash because of memory problems, and I just got a unknown hard drive error warning now. Is there any way to restore a hard drive’s health, or should I just invest in a new hard drive and transfer my operating system to it? It’s a Samsung SSD, 1TB, and only 3 years old. Thanks in advance.
