Computer shuts down after start but before Windows loads.

By reginald_stanton ·
My computer shuts down randomly after powering up, but only before Windows starts to load. After Windows starts to load, its stable (no shutdowns)! This behavior just started (ran without this incident for years). I'd like to believe its hardware, but there's that stability after Windows starts loading and the fact that no new devices have been added. In addition, its also stable after Linux starts loading. Is this some kinda ACPI or APM thing. USB devices with lights stay lit after power down (some go off if the power cable is removed and replugged back after a few minutes).

What type of computer is this?

by OH Smeg In reply to Computer shuts down after ...

If it's a desktop system it's possible that the BIOS Battery is going flat and needs replacing. That could cause this to happen.

Yea, its a desktop. I'll check the CMOS battery. But question, why does the behavior stop after an OS loads?

Well CMOS is the very basic level of Hardware Control

by OH Smeg In reply to Computer shuts down after ...

It comes into play long before the OS starts to load itself. If the System can boot to the stage that the OS becomes fully loaded the OS can then look after the Hardware Level things that need to happen.

Naturally enough if the OS can not load it can not run the Hardware.

caps

by brian In reply to Computer shuts down after ...

In addition to what Col said, you may want to check the motherboard (all of this post is assuming it is not a laptop). Though it is stable ONCE windows or Linux loads, the motherboard could be on its way out as well. When you open the case up, look at the capacitors on the MB and see if any of the tops are bubbled up or leaking (i have had this happen before). Depending on which caps are bad, it may still run dandy once running, but take FOREVER to run. What is bothering me is the fact that the system keeps power to the USB after shutdown. If you see no bad caps on the board, try Col's suggestion (usually about 3-5 bucks for a battery). If that still doesn't work, you may want to try a power supply (usually 40+ dollars). Since the system keeps power to USB after shutdown, the power supply could be on its way out as well, but first check the caps, then the battery, then power supply (take the cheaper options first).

by reginald_stanton In reply to caps

I thought about the CMOS battery thing (and hope that is the case, so I'll check it ASAP and let everyone know) but don't like the idea that the OS can circumvent hardware problems (cause 'em, yea, get around 'em...?). Especially things like MB capacitors. How can that be? I can kinda see it on the CMOS battery, cause the OS can theoretically manage the CMOS info using energy from the powersupply (somehow), but even that seems a stretch.
