Well, years ago I built a computer from spare parts, but that was in 1991 and a lot has changed. I've added my own drives and stuff until recently. So, being a cheapskate at heart, I'll always give it a try before taking it in, if I have a clue as to what I should try. Like when the Daughter dropped my laptop and the keyboard stopped working. Found video on YouTube about how to change keyboards. Took the old one out, blew the dust out, reseated it. Worked fine again. So, yeah, if it's memory I'll try. The Daughter says RAM is cheap.
Not sure it is, tho. Ran a memory diagnostics test on it and it came up with no faults. So...?
I can get a complete replacement of this machine, plus monitor, keyboard, and mouse, for about 85 quid on Amazon. I will probably do that, even if it's just to have it sitting in a closet for when this one does die. I was able to do a complete system backup, twice (on two different hard drives, for good measure) and created a system repair disc tonight, just also for safety-sake. Hopefully I will not need any of this.
Ran across a message on a computer problems website that was mentioning something about USBs and this type of thing. Stupidly did not bookmark it. (Sigh). It's been a long week.
