    Your electrical power, in your residence, is it feeding any electrical heating loads. Baseboard heaters, standalone units, etc.

    Maybe I should have asked do you have your computer connected to a UPS.

    Hi Ken,
    I googled 'UPS' and it talks about shopping....
    can you explain what it is?


    So bizzare but NO reboots since 8pm Sunday ( and has been on non stop!)

    Sure

    UPS is an Uninterruptible Power Supply.

    One example.

    Robot Check

    The unit plugs into the wall and then the computer plugs into it. The UPS usually has two sets of plugs, those on battery and those that just have surge protection.

    The idea is the electricity flows from wall plug to battery to computer. If the power flickers the computer does not see the flicker as the battery instantly steps in. Really good UPS's also watch voltage. If the voltage drops below x% then it kicks in.

    I had a client and their machine would Blue Screen at any given moment. One day I was sitting there and the lights dimmed like some large electrical load had turned on. Sure enough computer blue screened.

    Turns out it was a 1700 watt Honey heater in a giant pot of pure honey. We install UPS and the BSOD's stopped.


    So I was asking about your electrical loads. Baseboard heaters turn on randomly when its cold and can suck the life out of other electrical circuits.

    ok-
    I have normal plugs and nothing fancy plugged in. Just pc monitor lamp printer etc

    the only thing is i am near a railway line and up til a few years ago lights used to dim/flicker- but now i use a surge protector

    BUT
    that still wouldn't it explain it causing reboots every few days then none for 3 week, the 32 reboots in 2 days and now only one a day. Would it?

    Good news. I have literally JUST switched my PSU. It wasn't easy for me (1st time for everything) and had to take photos of where cables go to track my steps. Plus unclipping wires that are clipped together with a pair of lady's nail scissor but it's done.

    If I go 4 weeks without a reboot I will celebrate

    So roll on Christmas!

    Cool

    Surge protectors do nothing for dimming lights and especially flickering.

    Lets see what happens with new PSU.

    It is not what you have plugged in, it is how power is being delivered and total loads. Trains causing issues is different.

    Interesting- could be my imagination but can hear a faint humming noise from PC that I don't recall hearing before. The sort of sound a 'healthy' fan should make.

    I did check the old PSU fan was working a few weeks ago (the little fan at the back near where you plug in PC) and it was turning ok- but is it possible it was just not rotating well enough?

    Starting to feel optimistic!

    So it was the PSU. Never seen a PSU with this behavior. Normally it works or it don't.
    Glad you fix it. Point for your persistence.
