0crash0, Could you explain this better? The wireless card is a mini half card Intel AC7260, and it is installed in one slot. When installed, bluetooth works but wifi does NOT work. I am using Prema's bios mod, not the stock American Megatrends bios.

Well the network card doesn't show up in linux either, so it must be the socket on the motherboard is bad.

I'll try that. I'm not familiar with creating and using a "linux live cd" but google is my friend...

Actually I'm nearly convinced that the motherboard socket is faulty, after talking with 2 local repair shops. I have tried two different wireless cards in the computer and neither one. However, both wireless cards work in other computers. Also, as I mentioned I had a disk image backup on a separate hard drive. That backup was made when the wireless card was working fine, but using the backup hard drive also resulted in the computer failing to even recognize the card was there. I even then did a windows 10 reset on the backup hard drive and still the wireless card was not recognized. So I don't see how it could be a software problem, but please enlighten me if I'm wrong.

Well after talking with a local computer repair shop, it is most likely that the wireless card slot on the motherboard has a problem. So my question about replacing the motherboard is pertinent. My options are to replace the motherboard and keep the computer, use a USB wifi module (which sucks), or buy a new computer. I couldn't replace the computer I have for less than probably $1500 with the updates I've made to it, so replacing the motherboard seems like the best option.

I'm wondering if it is possible to get a replacement or improved motherboard for a Clevo W150ERQ? Google isn't coming up with much. I'm quite happy with the computer as a whole and the components I've updated are great, but might need to look into replacing the motherboard. What's prompting this question is a hardware problem with the connection between the wifi network card and motherboard. I've determined that the wifi card is fine (tested in another computer) but it will not show up in device manager, not even as an unrecognized device. Strangely, the bluetooth works just not the wifi. I'm looking into having a local computer shop try to repair it, but if that's not possible replacing the motherboard might be the next step. I really don't want to have a USB/wifi adapter hanging off the computer either.

Update: I have an image backup on a second hard drive, and when I swapped out the hard drives the wireless card was still not recognized by the computer. So I know that the wireless card itself works fine because it works in a separate computer. I also now know that it is not a driver/software issue because with the backup hard drive in place the wireless card was still not recognized, even though it had been working just fine before. So it seems apparent to me that the problem is a connection problem between the wireless card and the motherboard, or the MB itself. It should also be noted that I recently installed a new CPU, but the wireless card was working fine for a week after the CPU was installed. Any ideas where I should be looking for a loose connection etc? The wires connecting the card seem fine.

I have a Clevo W150ERQ with an Intel Dual wlan/bluetooth network card AC-7260. A week or so ago I updated to windows 10 doing a clean install. I noticed right away that the bluetooth would randomly just turn off or I would drop the connection to my bluetooth mouse. Sometimes the mouse would reconnect right away, other times I would have to use the physical buttons to turn off, then turn on the laptop bluetooth in order for the mouse to reconnect. This happened sporadically and all drivers were up to date. The problem was annoying enough that I thought I would try to uninstall the device in device manager, take the network card out, restart windows, shut down, re-install the network card and let windows re-install the card drivers etc. However, when I put the card back in the computer the wlan is not recognized by the computer. The device does not show up under network adapters. But very strangely, the bluetooth DOES work and shows "Intel Wireless Bluetooth" in device manager. I was careful to make sure the wires are connected properly. There are three wires labeled "ww1" "ww2" and "ww3". "ww3" was not originally used. (What is that ww3 wire for?) How can it be that the bluetooth shows up but not the wifi? I should also say that I have a spare Intel 7260 card that I installed and it too did not work. I know that both network cards work (tested in another computer). So the problem has to be with the Clevo computer, either software or hardware. Any advice is much appreciated.

Thanks for the info and for taking the time to look some of these things up. I was aware of much of this. But a few things: 1. I'm not a gamer, but I do a lot of video and photo editing/rendering that takes a lot of processing power. That's the main reason I was looking in to overclocking. Overclocking the GPU is fairly easy and have not had problems with the settings I have chosen. Neither overclocking or underclocking the GPU seems to have much of any effect on the CPU temps when trying to overclock the CPU. 2. The heatsink has aluminum fins. 3. I do run benchmark tests with the fan at high speed using fn+1 4. I just installed the i7-3940XM and applied Gelid extreme paste on both the CPU and GPU. 5. Yes, the GPU cannot be changed because it is built into the motherboard. 6. I'm not familiar with the foil tape mod, and at this point I'm thinking that trying to overclock the CPU is near to impossible without taking rather extreme measures that aren't worth it for me. I'm trying to be content with the stock speeds which are a large improvement over the original i7-3630QM CPU.

I have been informed that undervolting is not possible for this cpu, so I'm stuck with the stock speeds.

I have searched for hours and can NOT find how to do this. I would like to undervolt my CPU. I have a Clevo W150ERQ with i7-3940XM running Prema bios. The Intel XTU doesn't give me the option to adjust voltage or to adjust multipliers for that matter. Going into bios I can increase the multiplier, but I don't see any option to undervolt. It's probably there I just don't know the terminology, but there's nothing related to CPU voltage that I can see. Any help would be much appreciated.

Thanks for the suggestions. Most of those are things I'm not willing to bother with as I don't feel it's worth the effort. However, undervolting is a possibility. How does undervolting affect the processor speed multipliers?

Well this all might be for nothing. If I increase the multiplier in bios on even one core by just +1 I get temps in the mid 90s and thermal throttling, so unless I'm missing something I won't be able to overclock the CPU due to thermal concerns. The multiplier cores at stock are 1 core = 39x 2 core = 38x 3 core = 37x 4 core = 37x and as I said if I increase any one of those by just 1 it gets too hot for my comfort.

Understood, but at default bios settings XTU gives me no option to increase the multiplier and stays at the default 1-core 39x. When I change the bios to increase the core multiplier, then XTU shows the increased multiplier (I set it at 40x) but again it is the max and I cannot set it higher in XTU. Of course, completely understood. I assure you I've spent hours doing google searches on this and have come up short. No worries.

Thank you Prema, I do greatly appreciate it. You must get tired of newbies like me... One follow up question, when I change the X-core ratio, does that apply the new settings, or does it simply enable the settings to be changed in IntelETU? Also, is there a list or a place where all the bios nomenclature is defined so that I can see exactly what all the settings do?
