"Itel processor 2.7GHz Dual Core, 2GB RAM, Gigabyte Board 41"
Not very helpful. Which "Itel" dual core? Pentium D, Pentium, Core 2 Duo? What type & speed of RAM? "Board 41"? What's that? If you want help, you need to be specific & you need to list your specs correctly.
Now tell us about this new power supply - make/model, wattage & amperage specs. Check the label.
