Question about PC Desktops

2 Answers

My computer won't start! It was shut down by the start menu and when I went back to it about an hour later, I push the button in to power the computer on and nothing is happening. Yes, it is plugged in correctly; no, there are no problems with the outlets. Not sure if it helps, but there was no storm of any sort present at the time this occuring. No fans, no beeping, nothing are present. The only sign of ANY life whatsoever, is on the back of the tower, where the power supply would be located, the green LED light is on and solid.. otherwise, there are no signs of life :(

    I have exactly the same problem. I replaced the Power Supply with a new one, but still no luck. I tried everything from pulling out all cables/devices and reattaching.
    I am thinking of replacing the power reset switch (though it tested ok with a multimeter) before even thinking of the mother board. Does anyone know what the part number for HP Paviloin a705w is?

Try this. While pushing and holding the start button, look at the back of the tower, where the power supply is, and see if the power supply fan turns.(you can't always hear the power supply fan running) Then release it and see if it stops. If this event occurs then your power supply is probably bad and needs to be replaced. To troubleshoot further you can replace the power supply with one that you know works, maybe from another computer, if available.

Another possibility is that one of the cables, inside the case, could be loose.

To reduce the risk of electrostatic discharge (ESD) while working inside your computer case, first unplug the unit from the wall outlet, then touch a bare metal surface with your hands, preferrably on the case.

Unplug it and hold the power button in for up to 60 seconds to discharge.

Is there an I/O button in the back of the computer? Make sure it is set to I.

You will have to get your power button unstuck. I do not know what type of button you have but if you would like to at least get your PC on without it instantly turning off, you can remove the power switch connector from the motherboard. You will eventually need to have the switch unstuck, or replaced though.

Acer Veriton M498g - ui3540c won't start


Need more info, Give as much detail as you can. What happens when you push the on/off button? Fan spin? LED's Blink? Any thing on the screen? Sound? Does the computer try to start and a second later shut down? Check the power cord, check the AC outlet? Is it on a UPS? Try AC outlet? Can you get to BIOS or Boot Menu? ETC.

I have a emachine that powers ou, power pack fan, cpu fan but not the hardrive. It shut down and now won't start up. No beeps


Unplug from AC, open the case, clean if necessary, reseat the memory mods, use Electronic Contact Cleaner spray on contacts, plug in, push the on/off button. Does it begin to start, and in a few seconds completly shuts down? No LED's , no fans, nothing? Sounds like a PSU failure. Mine went out in 6 years.

Hp dx2200 computer won't power off


If your HP computer refuses to power down, this means that there are still programs open that Windows can't close. Normally when you select the "Shut Down" button from your "Start" menu, Windows closes all open programs, then closes itself, and your basic input/output system (BIOS) turns off all of your hardware. If Windows can't close all open programs, your computer won't be able to power off. This means that you must close these programs yourself.

Right-click on the window of an open program on your Windows taskbar (Bottom of Screen) Click "Close Window." Windows manually closes the program. If a window appears on-screen indicating that Windows cannot get the program to close, click the "Force Close" button in this window to have Windows force the program to shut down. Repeat "Step 1" for any additional programs that are open on your computer. Click "Start." Click "Shut Down." Hope this helps.

Won't go into sleep mode


Which operating system ?


Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work.


This option cuts the power to your monitor, powers down the hard drive and pauses all functions until you awaken the computer from hibernation.


Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money!


Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow. Mouse over the arrow.


The Shut Down menu appears.

Point at "Sleep" and click on this option.

Your Windows 7 computer goes into sleep mode.


Wake your computer from sleep mode by jiggling the mouse.

There may be a delay of a few seconds before your hardware powers on.


All of your open programs are still open and your work is intact, just as you left it before the computer entered sleep mode.


Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time.


Click "Start" and select "Control Panel." Click "System and Security."

Click "Power Options."

A menu opens.


Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode.


If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity


Your Computer in sleep mode


First, save all of your work. Information in computer memory is not saved while your computer is on standby.


From the Start menu, select Settings, then Control Panel, then Power Management.


Click Standby Beside When I Push the Power Button.


Push the Power button.


Automatically Putting Your Computer on Standby


Save all work before leaving your computer.


From the Start menu, select Settings, then Control Panel.


Double-click Power Management.


Set the times that you want your system to go on standby, to shut off the monitor and to shut off the hard disks.


Click OK. Your computer will go on standby according to the schedule you have entered.


Putting Your Computer in Hibernation


From the Start menu, select Settings, then Control Panel.


Double-click Power Settings.


Click on the Advanced tab.


At the When I Push the Power Button On My Computer screen, click Hibernate.


Click the Power button.


Hope this helps.

Depending on how long the power was off, your desktop power supply circuit capacitors may have fully discharged during the power outage. This will effect how fast your computer will turn on when you press the power button. Turning off the power by pulling the cord, or a power outage while the computer was on will usually result in a message that Windows was not shut down down properly when you try to restart it. Also make sure your computer isn't plugged into a 'switched' receptacle that's wired to turn on a table lamp etc from a wall switch. It's usually the bottom half of the receptacle that's switched while the top plug is always 'hot' or powered and unswitched in a wall switch controlled recepacle situatation.

Vaughn it sounds like the power supply is going bad, try another known good working power supply. If that doesn't work then the motherboard would need to be replaced. If the power supply isn't giving the correct voltages that could cause the computer not to turn on. If the motheboard isn't able to convert the voltages properly then the motherboard could be faulty.
