Open it up and inspect the caps for bulges, leaks and such. Most makers will replace the board if you call it in.
There are quite a few startup problem threads but I don't know if any of them has a specific situation like mine. I recently did quite a few things to my computer (installing new printer, several programs, add external harddrive, etc). At the beginning everything was fine until last week. I usually turns my powerbar off after each use of my computer. Last week when I tried to turn my computer on, somehow it wouldn't boot. The computer was getting electricity, but it seemed like it was stuck there and there was no BIOS beep sound. So I turned everything off, powerbar off, unpluged the computer, and repluged, and restarted, and repeated twice. The computer then booted. If I don't turn off the powerbar, the computer can startup as usual. Once I turn the powerbar off, I have to repeat the unplug/start several times until the xp properly boot. One of the times I also got the repeated long BIOS beep signal (even though after another repeat I was able to start up my computer). I was going to do system restore, but my last restore point was no good. Does anyone know what this is about and how I might be able to fix this??? This computer is about 5yr old with pentium 4.
try looking in the BIOS to see what the power Mangment settings are.
You may not realize that by turning off the Power Bar will cause the 5 volt standby power to be removed from the mobo. [that is normally there ALL THE TIME]. The removal of the standby voltage is interpreted by the computer as a power interruption.
Thus, check in the BIOS to see what option for action is enabled for action after power interruption.
Some mobos have BIOS that allows the system to start after power interuption. I enable that, thus as soon as I turn the Power Bar on the system boots up.
Note that unplugging the power supply if it is plugged into the power bar is a redundant action. Turning the power bar off already turns off the Power supply.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
