My laptop is a Dell, with Windows 7, 2GB RAM, and an 80GB hard drive. I don't remember what is processing speed is, but you can probably make a general estimate, based on its RAM.
This is exclusively a "home/home office" laptop. I use it to stream Youtube videos while I'm laying on the bed (because I can just reach across and turn it off if I want, so I don't have to get out of bed to turn the playlist off at the desktop), to look up guides online when my desktop is running a full-screen game, and also as a secondary computer in my desktop isn't working right.
However, my laptop has, for a while now, spontaneously crashed on me. It's usually a blue screen of death. But what's really annoying is that, nine times out of ten, the screen will become excessively pixelated and I can't see anything. Sometimes, I'll still be in Windows, but it will actually show me TWO versions of the desktop, one on top of the other.
This is definitely a hardware problem, because in the rare event the blue screen does not result in heavy pixellation, it will tell me "Hardware failure. Contact system administrator." I wish it would tell me precisely which hardware part is the problem, but at least I know it's hardware.
How do I do a diagnosis to tell exactly what I need to swap out?
