No, there is no tax deduction available to students for the purchase of a computer. If you are self-employed, and use the computer for work, you can take a deduction, but other than that, it's eligible for a tax deduction.
Your purchase could qualify for a tax credit, but only if your computer is a necessary requirement for enrollment or attendance at an educational institution. If you are using the computer simply out of convenience, it most likely does not qualify for a tax credit.
