There are plenty of places to buy computers these days, including Walmart, Best Buy, etc. but where do you go when your computer is acting up? You can certainly take it back to those places if you bought a service plan, but if not, just take it over to Galveston Computers. The owner/operator is a nice man who wants to help in whatever way he can. The prices are reasonable (every computer servicer is going to overcharge for the knowledge and labor actually required to fix most computer problems) and he offers a free diagnostic service. He's honest and won't try to screw you over, at least in my dealings.
Bottom Line: Need some computer advice or service, go ahead and let him diagnose and price the fix.
