Windows 7: USB Wifi Adapter Freezes PC

Hi!

I'm having this problem for last one week, after boot my computer just freezes. When I boot without USB Wifi Adapter the computer runs okay. I have 2 different Wifi Adapters, with both of them its the same problem.

I followed this thread [Solved] USB devices freeze computer - Gigabyte - Motherboards-Memory , and disabled usb legacy support. the computer ran fine with USB adapter after that (last night) but today morning again its freezing.

Problem started with TP-Link wifi adapter, now i'm using Linksys Wifi Adapter.



driver update doesn't do a thing.. I read somewhere there could be IRQ conflict, how do i check that?


PC Config - Intel G41, Core2Quad 8300, HD5770, 4GB RAM

Please help!


Thanks
