I have a new HP 4620 Officejet and new Dell desktop computer with Windows 7. The printer causes the computer to go to blue screen when it's used. I am being told that this is most likely caused by Intel Chipset 7/C216 needing to be upgraded. I do have this chipset on my system. Is this the likely cause of the crashes? If so, if I upgrade, will this fix the problem? And, is it safe to do this upgrade?
