    Possible CPU problem advice please


    A few months ago I got the occasional desktop crash, suddenly, like a power cut.

    I also got the windows message about it being overloaded, etc, and restore chrome pages etc.

    I didn't think about it much. Just re-booted, and presumed it was because i had speakers running, external hdd playing music etc, maybe my pi was running, maybe not.

    Anyway, in the last few weeks it has happened far more, and sometimes cuts within minutes or even less. Once or twice the on off switch illuminated on and went off immediately.

    so I've took the case off, gave it a good dust inside, etc, using an air duster spray, and it made no difference.

    So I'm now thinking is it the power box, switch, or something else like the mobo which due to the age of the desktop , about 8 or 9 years, it was originally windows 7 and i upgraded it to windows 10 etc a couple of years with more RAM but that was all.

    Does anybody have any suggestions please, I am reluctant to upgrade as I like windows 10 and so long as they support it I don't want to change again.

    I did a speccy report, it isn't overheating.

    Also since I attached a new power lead its been fine, and now I'm reluctant to move it back or put the cover back on in case it disturbs it. I supposed blowing the dust out could have settled it down now and nothing is wrong.

    However, if the CPU is being overloaded, or crashed, how dangerous is it, is buying a new CPU still the best option.

    Windows 10 Home, version 22h2.

    First job when you have a crash is to run chkdsk as a crash will leave data not written

    How do you know that it is being overloaded?

    Over the years the heat sink gets clogged with dust.

    I would say that you should remove the fan without removing the heat sink and do a good clean with a vacuum and a paint brush.

    At the moment, I'm not supposed to be lifting stuff and bending too much LOL...... but I used a can of air and its been fine since, but I'm not putting the side of the case back together again or moving it !!

    So it could be the problem.

    Sorry.... it told me it was overloaded, or words to that effect, but i couldn't get a screenshot, because it cut out like a power cut, and when I re booted chrome enabled me to restore pages.

    If it's an old desktop or laptop, a rubber tap on the memory and graphics adapter pins, and a vacuum cleaner won't hurt.
    If that doesn't work create a small partition to install Windows in dual boot to see what happens.

    Never use a vacuum cleaner in a PC unless it has been certified as anti-static. The static electricity charge at the end of a vacuum hose, or worse yet the bristly brush attachment, is large enough to ruin a motherboard, CPU or the RAM.

    Compressed air and a camel hair (artist's brush) or hog's hair brush are all that should be used. Unless you have an anti-static vacuum.

    I've never had a problem with a vacuum cleaner on computers.

    It must be anti-static or don't produce.

    When shopping for such a vacuum look for those made to clean up toner power from printers and copiers, I have one made for the purpose.

    I'm now finding speccy reports my motherboard as 115 degs centigrade. But a large number of people say speccy often reports this as on ASUS mobos and is probably an error.

    How can I check this using other software or with my bios settings ?

    The PC has worked perfectly for a week since I used a whole can of air spray on it

    How about using an IR thermometer to see what component temps. are? How about directing a small fan at the open case?
