How Increase the Voltage level of a PC

hi
i want to increase the voltage level of the electricity so that i can burst my pc or any one.in vb.net 2005 plz help me

Don't do it!
The chances are pretty high that your CPU will indeed 'burst'. And besides, these settings are hardware dependant. Use BIOS or OEM software provided by the CPU manufacturer.

P.S. And you wouldn't be able to create a virus like that, sorry.

plz tell me the code how i can do that i want to make such an application

Use OEM software.

can u tell me that software name plz

exact name plz

It should have been supplied with your CPU or motherboard.
If you don't have it you should visit the website of your motherboard manufacturer and look it there. There's no universal software like this. Different chipsets require different software.

do u mind to tell me some sort of code in visual basic .net 2005
thnx in advance

You'll burn your CPU even if your motherboard supports such things. And I don't think it's possible with vb.net.
You can control ACPI, but this is not the same as overclocking. Here you can find some example: http://www.pbus-167.com/nhc/nhc_adva...r_acpi_methods
But overclocking should be done through the utilities that come with your hardware, NOBODY IN HIS RIGHT MIND DOES IT THE WAY YOU WANT IT TO DO.
