Installations and upgrades are a part of the life cycle of technology. Whether it's hardware, software or network, you need to perform installations and upgrades in a manner that protects your data. There is not much point getting a new storage drive if all your most critical data has been deleted.
Upgrades can extend the life cycle of your investment. Sure there are times when you need "New" but with the appropriate knowledge, Technology 411 can improve the situation with substantially smaller investments.
Installing a "Solid State Drive" ( SSD ) will make your machine run like new. The prices of SSD's have dropped significantly and are regularly placed on sale.
Another shortfall for most older devices is memory. Modern operating systems will run on the minimum but will perform substantially better with more and memory has also dropped in price over the years.
Since we don't keep hardware inventory you get real advice based on what you need, not what is in stock.
Before you buy, get Technology 411 involved.
