Firstly my PC decided to shut itself down on Friday night - no warning, just switched itself off. So I'm freaking a bit inside because my PC and I switched it back on; it started to boot up then switched itself off again, then booted up again without me touching it, switched itself off again... repeated this half a dozen times before finally booting up properly. It's been okay since, and my son the computer geek has told me it was probably a one-off (although he's champing at the bit to build me a new one!)so it looks like I'll be keeping it for a while yet. Mind you, it's seven years old, so I wouldn't be surprised if things started going wrong.
The second thing to worry me was my gas heater. With winter approaching (so they say!) I thought it was time to fire it up and make sure all was working okay, but it wouldn't stay lit. Frustrating! I had this problem once before, when it cost me nearly $400 to get it fixed, and I was reluctant to spend that much on it again, when it's over 20 years old now. I got online, looking for a replacement, and stumbled across a troubleshooting Q&A on the manufacturer's website. Someone else had reported the same problem, and there was a suggested course of action which I tried, and voila! my heater lives to warm me for another season!
