Worldwide PC sales in the first three months of 2010 grew 24.2%, according to IDC.
This is in sharp contrast with a 7% decline in the same period the year before.
The latest gains have helped reverse declines that started in the third quarter of 2008 as the world economic recession began to take hold.

IDC attributes much of the growth to economic recovery in emerging countries and improved business confidence.
Like Intel and AMD, IDC predicts a strong second quarter driven by product innovation that could push growth for the year to 15% or higher.
Hewlett-Packard (HP) recorded the most PC sales among suppliers in the first three months of the year, delivering a 20% increase over the year before.
HP's focus in emerging markets paid off, with especially strong performance in Asia Pacific (excluding Japan) and Latin America, IDC said.
Acer continued to capitalise on demand for its value-oriented product line, recording growth of 42% compared with a year ago.
Dell also saw gains in emerging regions and grew 21.1% year-on-year, in part due to improving business demand, said IDC.
Lenovo saw the biggest improvement among the top vendors, with 58% year-on-year growth in the first quarter.
IDC said renewed focus after restructuring, channel expansion and commercial sales accelerated growth from an already very strong fourth quarter.
Toshiba saw above average market performance in most regions except Emea. Notebook demand was especially strong in emerging regions, but the US also contributed strong results from the 2009 holiday season to deliver 29.4% year-on-year growth for the first quarter, IDC said.
