Answers :

There is no such thing as plugging something into 220v. That is the voltage at which your power supply will provide power to your computer. What you did was give your computer more power than it needed and you most likely burned out the mother board or other hardware.

Simple way to determine if this has happened. When you turn your computer on the first thing it will always do is run the bios of the MB and give you a beep code. 1 beep u are fine, more than one and u have hardware problems. No beeps....ahem...you need a new MB.

From what u stated you installed a new PSU and were actually able to run the Operating system since you were able to run a chkdsk option. So, if you hear the beep...your MB is fine. If you simply do not get a image on your monitor and the light stays "orange" (I haven't seen a red light on a monitor yet) then most likely u burned out your onboard/AGP/PCI graphics card.

I do not suggest that you continue to tamper with your PC hardware. But if you must, get a graphics card from a old computer or buy a new one and install it. I suggest a used one u may have in another tower as this may save you 40 to 100 bucks.

Now installing the drivers and checking the graphic config in the bios to make sure everything works fine.....you will have to post another request I guess. Good luck and please stop opening your PC if you don't know how to handle the inner parts. Just a suggestion.
Since something smoked I would look for physical damage on the motherboard and other cards. Make sure your video chip isn't visibly fried. If the physical damage is limited to the power supply I would definitely change it out, because it could damage other parts of your system and that's not a chance you want to take. Also, if the video is fried just get a video card and run with it.

Check the back of your sub to check your voltage range. You will see something like this: 110V-120V or 110V-220V. If you see the later, you are ready to go. If you see 110-120V only, you will need a power converter to power your speakers as well as a ... Logitech Z-2300 Computer Speakers

I bought a mag innovision model 780 monitor at a garage sale to use with my ACER mini laptop. This monitor has a manufacture date of January 2003 - it did not come with a power supply.
