System hangs after inserting a mPCIE Wireless card

[Nachiketh]

Hi Folks,
I recently bought a PC having a mPCIE slot for my peripheral cards. The system works fine as long as I do not plug in a mPCIE wireless card into this slot, Once I plug that in the system becomes extremely sluggish, takes about 10 mins for the BIOS screen and another 10 mins for the OS to load and then finally hangs at the login prompt. As soon as I disconnect the mPCIE card, the system resumes normal operation.

If any of you could please help me out in resolving this, it would be of great help! The following are the details of my system:
Processor : Intel Haswell Core i5
BIOS : AMI UEFI 2.4 (Version 5.010)
mPCIE : Intel Centrino Advanced N-6235
OS: Ubuntu 14.04
PC:Mini Computer

If you need any further information to help me debug this issue, do let me know! Thanks in advance.
Regards,
Nachiketh

You missed out one vital piece of info: make/model of motherboard (or make/model of PC if it's factory-built).

I bought the mini PC from Alibaba from a Chinese manufacturer, so it is a custom board. The following is the product link:
Mini Computer

I have already contacted the manufacturer and yet to get an update from him
Thanks for the reply!
