Acer Aspire V5 431 super slow, file explore lags and videos and images will load for a while

as the title says, starting up the laptop will take like 5 minutes, file explorer always lags and not responds, videos and images will load for a while when i open them in file explorer, opening softwares will sometimes freeze or lag the whole laptop, downloading files from the internet even if its as small as 100 mb will take a few hours, the storage size is 304 gb free out of 447 and thats alot, what i seem to notice is that in task manager google chrome will usually take the most disk/memory alongside antimalware service executable, any solutions?
