I bought a Gateway Profile 5-in-one used from sale of large number of corporate computers. Memory is upgradeable and I need to do it to get the computer fast enough to do graphics work. When I was ready to do it I found all four screws had been stripped, possibly done by IT personnel to keep users out of computer. How can I get the damn things out? It is way too late to bitch about it to the seller. And what if they have not only been stripped but super-glued?
