When you’re racing to meet a deadline and your computer suddenly freezes or flashes the dreaded Blue Screen of Death, you understand how critical regular maintenance and dependable support really are. For more than 28 years, we’ve solved virtually every computer issue imaginable—from cracked screens and failed hard drives to virus infections, system errors, and everything in between. There’s almost no problem we haven’t seen before.

Our technicians are local St. Louis professionals, not outsourced or overseas. You never have to ship your computer away or wait weeks for service. At Dimension Computer, we provide fast, expert repair for a wide range of hardware including desktops, laptops, and more.

We are Certified Resellers for ACER, DELL, HP, and LENOVO desktops and notebooks. In addition to repairs, we’re a trusted source for Certified Refurbished PCs and laptops direct from the manufacturers—systems in like‑new condition, many of which are still sold new in stores.

We also sit down with you one‑on‑one to ensure your computers are set up perfectly, configured to your needs, and ready to perform at their best. This level of personal, hands‑on service is rare in our industry — and it’s one of the biggest things that sets us apart.

Looking for something custom? We also build high‑performance desktops and carry a large selection of used and off‑lease computers, all fully tested, optimized, and ready to go with Windows 11.

Call us today at 636‑527‑9660 for fast, friendly, and professional service.
