Turn it off and un-plug it from the outlet, "otherwise it still draws power", then clear the cmos, that can be done by removing the battery that looks like a quarter on the motherboard, if you aren't comfortable taking the cover off your computer then don't. But if you are leave that battery out for a minute or two, that is where the settings are stored. Put it back in, and re boot. You will need to put back some of your settings, but if it still won't run, it's really hard to tell without running a volt meter across some of your internal connections. I hope it just lost the settings for your pocketbooks sake, or you may need a new power supply, if you do please let us know there are stores online that can save you 50% over what the retail stores charge, merry Christmas and hope it works for you

Pc not booting


If you hear the CPU fan turn on that doesn't mean the CPU itself is working. It can be only that the motherboard is getting power. Check all your connections such as monitor and peripherals and re-connect them. If you still don't get P.O.S.T. or ANY letters or boot options on your screen then your CPU is dead. (unless your monitor is bad)
Another easy diagnostic is using your ears. For example the pitch sound of the fan in some motherboards tends to lower and then increase because it's reading of the hard drive. This means your CPU is ok but either your graphics connection is bad or your monitor is.

My Dell Latitude D620 is constantly spiking at 100% cpu, the problem arises especially when running the mouse over any program, it basically locks down my whole computer and nothing will run, it always...


It sounds like there could be a virus on your computer that is using up all of your CPU resources. Try to monitor the processes and CPU usage, buy pushing Ctrl + Alt + Del at the same time. This will open up the Task Manager on XP, or show you a menu screen on Windows Vista and 7, and you can click on start task manager at the bottom. View all your processes and how much cpu usage is being taken up from those processes. Look for the process using the highest cpu usage when it spikes to 100% and please repost the process name!

In the mean time might I suggest running and anti-virus scan, scanning for malware, and spyware as well. If you do not have any of these programs, I would suggest using either AVG, or Avira Anti-Virus, Malwarebytes, and Super Anti-Spyware, all of which are free programs that can be downloaded here!

Do you have an separate VGA card to try and then hook your monitor up to this card.
Actually does the rest of the PC work. Powers up fine and and keyboard and mouse seem to work?

When i press power buton computers, on/off led just blinks once,cpu fan turn few times and stop, power supply fan also turn few times and stop and computer does not start.


Possible bad power supply, hard drive, and or CPU. If there is a computer repair store close to you, I would take the hard drive to them and have it checked out thoroughly to make sure all the sectors are in tact and possibly have the power supply OHM'd to make sure the proper amount of voltage is coming out in order to turn the computer on in the first place.

Replaced motherboard and power supply. Monitor says No VGA Signal and No DVI Signal, then goes to sleep. Will not wake. Unable to load OS because I cannot view the monitor.


Power up your computer. As soon as you can open the DVD/CD drawer and put in your OS CD. shut down the computer then reboot. Let me know how you make out. Thanks Dana

My computer cant turn on and its making noises


Did you your CPU Fan inside, that's the one who make some noises inside.
If your computer is failing to start then check CPU inside, all the peripherals double check on it. From VGA Card, Memory and other devices, maybe its not properly connected inside. Good luck!
