Hello everyone, I have planned to upgrade the my old computer for various purpose, so I have done some changes like I have upgraded Ram, formatted windows XP and installed Windows 7. I have done all this things properly. I have also put PCI-E ATI HD 2400 and in second slot I have put PCI-E Saffire Radeon HD 4350 and both slot have same problem. When I use process explorer, it shows no card installed on board, and 0% hardware interrupts and 20% CPU usage. When I put HDMI card on board it shows 60-70% hardware interrupts and CPU usage is 100% everytime. Can any one help me please to solve this problem? Reply.
