Upgrade RAM and other stuff

[Discord]

The guy working at the computer centre needs a good foot up his arse, unless you've confused something. Let me guess, he also tried selling you the RAM-chip?

Your internet might not work for a good number of reasons, e.g. malicious software, messed up driver or hardware, etc. Your HDDs (hard-drives), which you defragmented, have nothing to do with it at all. In fact, they're probably the least related components after your sound-card. I don't know how much RAM you have, but I honestly doubt that it will not suffice to run IE or Firefox, so that's also gullies.

To be frank, viruses/spyware could be the problem, but as far as I am aware viruses can damage pretty much anything in your OS, making it no longer functional. While they often are the problem, saying, without a detailed inspection, that a system doesn't work because of them specifically would be quite stupid.

As for RAM upgrades in laptops, yes, you can do it very easily in some models. Check the bottom of your notebook. There might be a 2x3cm lid ,which can be either opened or unscrewed with a common driver. If it says RAM next to it, that's the one. Some models, however don't have external upgrade-slots, making an upgrade practically impossible for anyone without an expertise in hardware. From your questions I'm guessing that you are no IT-specialist.

NB: If you find such a slot, first make sure that it's actually empty. Sometimes you'll find a chip inside. And remember, you'll often need a RAM chip compatible with your model, thus I'd suggest asking somebody who knows a little about PCs (obviously not the guy from the computer centre), i.e. write down your models number.
