I posted last winter about my computer rebooting on its own. I ended up having to take it in to have it repaired when one of the reboots lost some of the BIOS stuff. Got it back and they had added RAM as I requested. However it did still reboot. I did get a heavier duty power surge protector which told me that the outlet i was using had a line fault. So I then ran the surge protector to a different outlet. Then it seldom rebooted to the point there were months it did not happen at all.
However as we got way below zero temperatures here in WI, it has now started doing it again. I questioned if it might be the furnace running so much was affecting or dipping what power it was getting. So then I got a backup battery one. Then shortly after that, we had some sleet and fun weather and I was at the puter when the house powere flickered off and back on. It was enough for the microwave to show power failure. The backup battery surge protector did kick in for a very short time cuz it has a little beeping sound, but about the same time the puter rebooted again. It also did it a couple other times the same nite.
The timing just seems to indicate the puter has more problems when the furnace has to kick in a lot. The furnace is new...its a gas one, and I can say that it is not using as much power as the old oil guzzler that got replaced when I bought the house in 2008! When that kicked in sometimes the lights would flicker as the banging and noisy motor would start up.
I have been told by puter person that it is possible the power supply might have been affected by the bad electrical outlet I had been using and now its just more sensitive to fluctuations on the power.
So now I am debating taking it to store and having them replace the power supply...which I think will probably be just under $100 if they put it in. I am not sure if this makes sense or not. New puters have gotten so much cheaper I could probably get a pretty good one for not all that much more. I just hate changing stuff and really am not that crazy about having to rearrange everything to find room for a new computer.
Does tossing another $100 on the current one make sense? Mine uses Windows XP which I am very comfortable with. Also I have debated maybe getting a laptop....but really don't have the room to put that up in addition to a desktop.
