External monitor randomly stopped working

Q: External monitor randomly stopped working

I have a Windows 10 laptop and an external monitor. The monitor was working perfectly for a few weeks, until one day I switched on the laptop to find that the monitor was no longer working. Going to 'Display Settings' only showed one monitor, and pressing 'Detect' said 'Didn't detect another display'.

After updating all drivers, then purchasing new leads and adapters for the monitor, I still couldn't get it to work. Then I stumbled upon the 'Hardware and devices' troubleshooter which, after restarting my computer, made it work.

Less than a week later, I just restarted my machine and suddenly it's not working again. This time, the troubleshooter isn't fixing it. Every time, it just says to restart my computer to finish applying updates/drivers but restarting doesn't help.

Anyone have ideas how I can fix this?

Cheers

I have the USBc to HDMI connector from Dell, to connect my XPS13 to a second LG monitor.
I have been using it without problems for 2 years. I use it every day. Same setup.
Since friday 29/12 it stopped working.
I tried to connect my laptop to different monitors. I did driver updates and even tried to roll back my Intel driver. I disabled the WIFI. (and tried putting it on airplane mode). But nothing helps.
I guess some of those latest BIOS updates, HD driver update, ... caused the problem.
Can somebody please help. It's urgent. I need my laptop+second screen for my work.

My laptop Lenovo Flex 2-14 has been working fine with multiple displays for 2 years. A few days ago, it stopped recognizing the HDMI output. Notes:The Intel Graphics driver is the latestWindows drivers are the latestIssue:1) When the external monitor is plugged in, I cannot open any folders or the windows explorer. As soon as I unplug the external monitor, the folders can open.2) The Intel HD Graphics control panel's interface is not usable as can be seen in the screenshot below. I have tried restarting, but that does not help. Unplugging the external monitor does not help either. It seems to be permanent.

I've been running this Z580 for a year or so, and updated to Windows 10 a couple of months ago. Both the laptop display and an external monitor (HPw1907 vga) have been working fine. The other day, the external monitor just stopped working.   I check the device manager and the Intel HD Graphics 4000 display adapter is disabled, due to a Code 43. I have tried rolling back to an earlier restore point, I've uninstalled and reinstalled several versions of the Intel graphics adapter, up through the current compatible one. The most recent display adapter driver from Intel is apparently not hardware compatible with this adapter. The funny thing, is that the driver wants to work! On booting, while the black and white Lenovo splash screen is displayed, with the little circular Windows logo circling around, I can move the cursor back and forth between monitors. As soon as the screen turns blue (I assume with Windows drivers loading) the external monitor blanks out and I'm back to one screen.  Based on that behavior, I'm wondering if it's not a display driver that is specfically the problem, since I've loaded up the latest drivers several times, but if maybe a recent Windows update has sneaked in a driver or component for something else that is causing the Intel driver to crash. Any thoughts?  Back in earlier versions of Windows, you could have the system load one component at a time during boot, so you could check for incompatibilities. So, if the... Read more

Well a while back my wireless networking hardware stopped working. Now whenever I try to turn my switch on it stay with the orange light instead of blue (meaning it doesn't work anymore). When I try to diagnose why I can't find any networks it says: 'This computer does not have a wireless network adapter installed and configured'. Then below that it has a click able box that says 'Install wireless networking hardware and verify the correct drivers are downloaded'. So, naturally, I click this box and it takes me to windows help and gives me a list of options such as: 'I installed new drivers and they do not work' and 'My driver used to work, but now it doesn't.' So I click on 'My driver used to work, but now it doesn't.' From there it says that I should install windows updates, which I have many a time. It also says I can try 'rolling back' my driver to a previous version, which also, I have tried many a time only for it to do nothing. I can't update my driver to a newer version either. So for a couple months I was just like oh well I'll let it be not that big of a deal. However, recently, it started working again, I boot up my laptop and it says 'Wi-Lan (or whatever it is called) Enabled' and the blue light was on my switch meaning it worked. So I was like alright sweet not sure what happened but I'm not complaining. The next day, does it work? no, it went back to as it was - not working, saying to check windows update, etc. Anyway, I'm wondering if anyone can tell me what i... Read more

I  have my HP Envy (with a touch screen) laptop connected to an Acer monitor.  It has worked well for over a year.  It was working fine today (as an external monitor) when suddenly the external screen went blank and the laptop went back to being the display.  I have tried everything I can think of to get the external monitor to work again:  I tried rebooting the computer and the monitor, checking the HDMI connections, replacing the HDMI cable, etc.  I believe it is a computer problem because when I hit f4 and select  second screen only, and hit enter, the laptop continues to be a display but nothing shows on the external screen.

Okay, so I had no problem with the wi-fi up until today. Yesterday all was fine and today I turned my laptop on and wifi was not working. Connecting to my home network is not possible, it comes up "unable to connect to this network". I have read up online and tried to delete/reinstall and update drivers, tried to delete and reinstall wireless router, tried to renew ip. This is where the problem comes in. As I try to renew or config ip, it comes up with "media disconnected" for all wireless, ethernet and bluetooth sections. No action can be performed when media is disconnected. I would try and forget my network, but there are no remembered networks on my sistem. Really need help. Thank you in advance.

Hi, we have a D-Link DSL604 G Wireless router, but for some reason the internet has completely stopped responding one one computer. It's connected over an ethernet cable and can communicate with the router fine, but just the internet won't work.

It's fine on my wired connection and the wireless connection, but not on this one pc. I have ran ewido and found a few tracking cookies and i have a HJT log here too, although i'll get a new one tomorrow because this one's a few days old.

It has Norton Internet Security 2004 installed (unsubscribed). I tried starting up without it, because it has Zone Alarm Security Suite too, but it still didn't work.

I just recently got some amazing advice here on there forums and solved some strange problems with my computer.

however, just recently, I've noticed several programs that rely on an internet connection (such as iTunes store and sometimes AIM, nothing illegal) suddenly stopped working.

The iTunes music store simply never connects, AIM sometimes does but mostly doesn't, but the weird part is all the while my internet browser works just fine and at pretty fast speeds. So i'm fairly certain the internet connection is not the culprit, seeing how Firefox works like a dream but some other programs don't.

Also, sometimes both IE and Firefox won't be able to download things online. some things work fine, large files and small, but other items simply cause the searching indicator thing in the corner spin forever with no result, even after several attempts and even restarting my computer and waiting for a while.

I also tried disabling my firewall (though extremely briefly, just to test the problem) thinking maybe some things were just being blocked all of a sudden, but the same things keeps happening. I even tried reinstalling iTunes, IE, and Firefox but the problem persists. it's obviously not a huge urgent problem, but very annoying all the same, especially since not only am I very into media but I make almost all my purchases and downloads online because it's easier, cheaper, and in greater supply than in any local store.

Hi everyone,

I tried system restore, but it failed. The control panel shows that the driver is properly installed and up to date.
 
Any help?

A:Track pad randomly stopped working

Two possibilities immediately come to mind. One, you may have accidentally switched the trackpad off. I think on a Satellite it is the Fn key and F6, but I'm working from memory here. Look at your Function keys and one of them will have some symbol that looks like a mouse and/or a trackpad. You use this, with the Fn key to toggle the trackpad off and on.
 
The other possibility is that your trackpad may be on the way out. They are, I believe, replaceable if you feel up to it, but the simplest solution is to use a USB connected mouse. As I don't like trackpads, I normally plug a mouse in and switch the pad off if I'm doing anything other than casual work on a laptop.

Hello Everyone,

This is my first thread, so be gentle with me. Im not as tech savvy as I'm sure the lot of you are, but I can do some things.

My wife's PC encountered an issue on the weekend in which the corded Ethernet stopped connection was MIA suddenly.
I have:
- restarted modem and router.
- plugged Ethernet cable originally from PC into my laptop (connection was present)
- checked for driver issues, uninstalled the LAN driver and restarted.
- changed the Ethernet cord out.
- Windows N&S Troubleshooter reports no issues.

At this point I suspect its a problem with the port itself, the PC was custom made and has only one Ethernet port.

Im considering a restoring to factory settings to see if it could fix the issue, but wanted to get a second opinion before I back everything up.

Thank's in advance

However, my personal laptop which is connected to my router through the Ethernet cable worked fine for a few days. Then the internet on it went out, which my Windows troubleshooter told me was my DNS server not responding. Which I fixed by changing my preferred DNS server to 208.067.222.222 which fixed it on my laptop but has not fixed the wireless. I have a Westell Versalink Model 327W router if that helps at all.

You will definitely want to perform a reset on the router using the reset button on the router. Router's typically will lose wireless while the wired connections stay active.

Sometimes a 30-30-30 reset is required to fix these types of problems.

Ok so i've been running Windows 7 for like 2-3 months on my pc and up until this week it was working fine. For some reason this past week the pc has been turning off on me and then the light on the pc proceeds to start blinking in 1-2 second intervals. Well tonight i feel asleep with the pc on and it did this and usually i have to disconnect the power to turn it on but when i went to do this it doesnt turn on properly. The pc sounds like its powering up but its not powering up its components. The screen does not turn on and it doesn't turn on my external HDD the right way.(My external HDD usually takes like 3-4 seconds to turn on and the light on it usually blinks a couple times but it does not do this now).

Hi.

I have a Samsung ES15 digital camera with which I use a Sandisk Ultra 16gb class 4 sdhc, using windows 7. I inserted it into my laptops sd card reader, and could view the files. For some reason after trying to select certain files and change from tile view to list view, the window froze for a little while. I could see about 50 icons then when scrolling down the remaining files didn't have an icon. Selecting one of these to open and in the file viewer it said this file may have been deleted or removed (from what i can remember).
I then removed the card (Using 'safely remove hardware' tool). Then upon reinserting the disk i get the message 'You must format the disk in drive before using it'. When inserting into my camera it says 'card error'. But if i format the card all the current data will be erased.
I then used a software called Recuva to try and recover some files before formatting, but nothing was found even in deep scan.

What can I do, I really need those pictures/video clips.

Also, i noticed a funny thing when i first inserted the card. There were about 5 folders named as letters (N, O..). No idea how they got there, but when opening it would let me in saying those folders may be on the harddrive instead. There was also two files with no file extensions, with just symbols in the name (!$...).
The only thing I know of, is changing the rotation of a few images last week from my laptop - which then couldnt be viewed on my camera.

A:SD card randomly stopped working

Sadly you are probably out of luck, SD cards like all storage devices fail all the time.

I'd try PhotoRec first: http://www.cgsecurity.org/wiki/PhotoRec
PhotoRec guide: http://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step

You can try these programs as well and see if they have any better luck then Recuva: http://www.computerworld.com/s/arti...covery_tools_for_SD_cards_USB_drives_and_more

Just as an FYI, you really shouldn't work on the pictures while they are on the SD Card, you should copy them off the SD before editing them. SD cards have very limited read/write cycles. Most times once a photo is edited(ie. rotated) many camera's won't open them anymore. Additional, just like the SD has failed so can your computer's hard drive and you can lose everything just as easily so hopefully you have a very well established data backup for your computer as well.

Very annoying problem - every now and then the monitor blacks out for 2 seconds and comes back.

Monitor is powered all the time.
HDMI cable changed twice and does not solve the problem.

Seems like a change of resolution or a reset - can the problem be in the graphic card? Otherwise maybe the HDMI port itself detecting strange stuff?

Please help I'm getting crazy as I work 90% of the time on external monitor.

Thanks

A:Portg Z30-A-1E1 - External monitor blacks out randomly

Two points would be interesting:

1) Notebook model/name
2) Preinstalled system

Furthermore it would be interesting to know if whether the external monitor works properly in connection with another notebook…
Please check it because it could be possible that your external monitor could be affected.

But if it’s not the external monitor issue, I would recommend you to reinstall the graphic card driver as well as to check the monitor functionality using different screen resolutions.

Hi all,

This is my first post to this forum, and I'm looking forward to meeting and greeting, as well as solving my issue. I consider myself fairly computer savvy, but have been unable to tackle this problem. My specs are posted. Here goes:

I've installed W7 Ultimate 64 bit on my notebook, and often use it connected to an external monitor. The monitor in question is a Samsung 216bw LCD at 1680x1050 and connected via HDMI/DVI cord (HDMI out on notebook and DVI in on monitor). I am using a ATI Mobility Radeon HD4650 card.

My notebook turns off randomly when connected to this monitor. It used to turn off randomly when on the notebook monitor also after being idle for a bit, but I fixed this with different power settings. It doesn't seem to matter what I am doing - anything from internet browsing to games. When it shuts off, I do not get a BSOD, a shut down warning, or anything - it simply turns off like it lost power. I have to turn it back on manually, but have never had problems with it turning back on. It asks me if I want to boot into safe mode, and after I choose it will boot like nothing ever happened.

The only thing in the event viewer is the "Kernel Power" and "6008 event" errors that notify me that it shut off, but it doesn't give me more info to go off of. All of the bug checks are 0x0.

Then:

So my USB ports decided to stop working.

I have two ports and I've tried placing three different items (two mice and 1 webcam) in all the ports, no avail. Even the light under my mouse isn't lighting up. I restarted twice and when I go to device manager there are no exclamation marks or anything wrong under USB tab.

I even uninstalled all my USb serial controllers and restarted and they got installed back but still nothing. Then I disabled selective suspend and nothing too. =[

I've noticed that nobody's replied to your post, so I figured I'd try to say at least a little something. I'm not too sure that it'd be of any help to you, but have you checked any settings in your BIOS that might be responsible for the control of it?

I have a Dell Inspiron 1525 and it's about 5 years old (can't really afford a new one right now). I'm running on windows 7.

The other day, my computer randomly disconnected from the wireless connection in my house. It cannot connect to the Internet at all. It isn't my router, because I've restarted it a lot of times and it works fine on my iPad and the other computers in the house.

When the problem first arose, my computer said that there was another computer with the same IP address on the wireless, and I needed to check with a system administrator. Since then, that message hasn't shown up again and now when I try troubleshooting, it can only suggest that I restart the router (it isn't the router!)

I'm a huge beginner so I haven't tried much more than restarting the router, restarting my computer, or restarting the Internet switch on my laptop.

Please let me know if there is anything I can do!!

A:HDMI sound randomly stopped working

The HDMI is generated by the video card. If the HDMI is set as the default audio playback device and there is still no audio, its most likey a problem in the video card.

One thing you haven't tried, reseating the video card. Its a long shot but give it a try. Power off the PC before reseating (unplugging and plugging back in).

My graphics card is ati radeon 3450. i know its older but thats fine for me. money is tight so if so i want to avoid buying anything. im using Windows 7 x64. The MSFixit for Aero says that my graphics card does not support Aero. I know is false because its been working fine. I have directx 11 installed currently. I am all the way up to date on Windows updates. I have downloaded the latest driver for my card from ati's website. tried uninstalling and reinstalling it. Looked at my system restore points it shows nothing happened within a few days of my problem starting. im not sure what other info to give...thanks for your help!

Yesterday I was using my laptop, everything was working fine, I left it for a couple of hours whilst I went away to do something else, when I came back it was in Standby Mode, I powered on & I noticed that my wireless wasn't picking up my network, I tried multiple restarts, installing the device driver again & switching to switch on the side to no avail it just has a Orange light & does nothing.

Anyone know anything else I could try?

Really hope it's something software related, my DVD drive failed a few months back, hope I don't have to spend more money on it.

A:Laptop Wireless Randomly Stopped Working

You've done the driver, good. You've checked the switch, good. I doubt a System Restore will help here, but you could also try that.

Also, most of the laptops face the problem with the residual charge storage. Residual charge gets stored near the RAM chips of the laptop. If the voltage of the residual charge reaches threshold then the system will not be able to access the memory and hence will give some problems while working. To bring the laptop back to the working state, you will have to clear the residual charge which is stored on the laptop. To clear the residual charge, shut down the laptop and disconnect it from the AC source. Remove the battery and then press the power button of the laptop for about 30 seconds. Replace the battery and see if the problem still persists or not.

I woke up this morning and some of the keys on my keyboard have stopped working.

Im nearly 100% sure it isnt a faulty keyboard but rather a virus or something that is remapping my keyboard. The keyboard has been working fine up until today when the f, y, m, and ' keys stopped working all at once. Nothing spilled on the keyboard.. nothing like that. Ive tried a system restore but it didnt solve anything.

I tried to do some research on my own, but didnt find much.. one guy had the same problem, but I didnt see any concrete fixes.

One thing that makes me think its a remapping problem is that when i hold down the f, m, y, and ' keys and hit x, the return is " \eqx ". Holding different combos of the keys that arent working yields different results, but results nonetheless, and since theres some sort of return when i hit the keys, i assume they still work but something on the computer happened. The other person who had this issue that I found gave me the idea of holding down the keys and hitting x, since he did it and had the same results.

Is there a known virus that I may have? Any way to restore the key set/map to factory defaults? Anyone have any idea whats going on here?

Thanks

Hey guys,

Normally I can fix most issues with the PC's I maintain, but recently my brother's audio on his PC stopped working. It uses the AC97 chipset, and I have tried multiple drivers etc to fix it, but not getting anywhere.

Just wondering if anyone else has experienced a similar issue, its an asrock k7gs41s I believe. Its also running XP, and I'd rather not format it, unless this would be the only likely fix.

Cheers,
Nic
 

A:AC97 Audio stopped working randomly.

im sorry to say I also have the A97 sound stuff in my lappy
one day i was playing happily ... listening to music ... then the speakers started to distort!
i turned off the music and ran some speaker tests and eventually the problem cleared up.
next time i turned the laptop on i didnt hear anything .. when i went to play music i got the error "media player cannot play the file as there is no audio hardware present"

i had a look in device manager and my sound stuff wasnt there

restarted the system and it worked fine again

but a few days later the windows seems to think that the audio hardware does not exist in my machine!! its so frustrating!
i contacted acer and they said to return my laptop to factory settings ... which didnt work
so acer wanted to take my laptop from me ... for 8 weeks!!!! i cant realistically be without my laptop for more than a week as i need it for work, presentations and university.
even though my laptop is still in warrenty period they will not give me a like for like transfer!

in the end and bought a really nice creative 5.1 external sound card and its really good!

should have been 45 but because it was the last one in stock at comet they sold it to me for 20

tho i really would like my on-board sound to work again because lugging external speakers about isnt really handy.

so i guess my advice is to expect the worst and buy another sound card preferably creative!


if anyone has any suggestions i woudl ... Read more

My sound stopped working last night, and everything I have tried hasn't worked. I've had this computer for 2 years using vista.

Here are the symptoms:
In the "playback and recording devices", it says my headphones are working.
If I try to do the "test" option, it gives me a failed to play test tone error.
If I use my microphone on another laptop that also has vista, it works
It's obviously plugged in. I have tried reinstalling the drivers and I've restarted my pc, still doesn't work
I have tried restarting windows audio in services.msc, doesn't work
the "roll back drivers" option is greyed out for me in device manager
Googling hasn't helped me either, none of the solutions so far have solved my problem. Even some method involving regedit.

So I'm exhausted and a bit frustrated. Does anyone know?

Problem started a few weeks ago. Not sure exactly if anything changed on my PC in terms of software. I know there have been no hardware changes. I am having horrible WiFi capabilities on my PC. Every other device in my household works perfectly fine. My PC is custom-built, running Windows 7 64-bit Home Premium. The BIOS and drivers are all updated. I was using a TP-Link USB WiFi adapter, which seemingly out of nowhere started running slowly. Then, the Internet would disconnect randomly and intermittently, or slow to almost a crawl. Since then, I ordered 2 more WiFi adapters (Panda and Linksys). All 3 adapters seem to work just fine on my laptop. All of them do the same thing on my PC. Oddly, the Linksys adapter worked beautifully for a couple minutes right after the installation. However, it eventually went back to horribly slow download speeds and/or intermittent connection. Nevertheless, I know the problem is not with the adapters, since they work fine on other machines. I have tried swapping out my keyboard, mouse, etc. with all of the available USB ports to no avail. The keyboard and mouse work fine in all of the USB ports, but the adapters don't work no matter what ports I use. Recently, I ran CCleaner, cleaned up the system and registry, did a fresh install of the WiFi adapter, and still it sucks (again, though, the adapter worked GREAT for a minute or two, then the connection pooped out). HELP??? Never seen this problem in all my years of building P... Read more

Hello! So my notebook has a lovely function key line-up that lets me adjust screen brightness, turn the backlight on the keyboard, mute and adjust volume, pause/play/fast-forward/rewind, and turn the wi-fi on and off. I have never had a problem with these keys and use them all the time, but they all randomly stopped working a few days ago. I've tried pressing them in combination with the fn key, but they still don't work. And when I do press them, it seems like they are doing other stuff (for example, if I press f6/mute, the content of the google search/address  bar will become highlighted).  I thought maybe my cat stepped on some combo that turned the function keys off, but I haven't been able to find anything under "settings" that would allow me to turn them back on. I did the BIOS thing - they were already enabled in there, so I disabled, restarted, tried the keys with no luck, shut down, enabled, restarted, and they still don't work.  I've been browsing the forums and downloading drivers that people have posted, but that hasn't helped.  I've gone into the device manager and made sure my keyboard and monitor drivers are up to date.  I've tried going through HP support for updated drivers, however Windows 10 isn't an option for my notebook, only Windows 8 and Windows 8.1, and neither of those had a hotkeys support driver option anyway. And before you ask, I've been running Windows 10 for a long time now without any trou... Read more

I can't find a solution anywhere, here's the situation..

I am running Windows 7 Ultimate, the mouse is a Microsoft Wireless Optical Mouse 2000 (along with the keyboard)

So i've been running the windows 7 RC for a long time now, i'm telling you this because i know many will put it down to the fact that it's probably not stable, which in fact i don't think is the reason at all.

So today i was just browsing the internet etc, when suddenly my mouse goes a bit jurky then just stops. I tohught don't panic, theyll be a simple solution. So i checked the batterys, fine (i knew they were anyway as the led was still on normally), i knew it cant be drivers etc as the keyboard was still working.
Next i thought it must be the mouse itself, so i unplugged everything and booted up with a mouse i used to use (a plug in 1, u no with the green end) and guess what ... not working! So it must be something to do with the computer, so i reboot with my microsoft mouse and check the driver, servies (mouhid.sys etc) and the process, and my computer just says that everything is working fine. I really don't understand, iv re installed drivers, gone back to previous versions of drivers, uninstalled then re installed windows updates, system restored, but still no luck. Please not that I have been doing everything you are reading with my keyboard!)

Does anybody know what could be wrong?
 

A:Solved: Mouse randomly stopped working!

Try in Safe Mode and see if the problem persists

How to Start in Safemode

1. Restart your computer.
2. Before the windows logo you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
3. Select the option for Safe Mode using the arrow keys.
4. Then press enter on your keyboard to boot into Safe Mode.
5. Do whatever tasks you require and when you are done reboot to boot back into normal mode..

EightForums,

I have a MacBook Pro running Windows 8 (via BootCamp) and I was running games on Steam.

Randomly, the game froze, and my Xbox 360 controller stopped responding. When I exited out to try and fix the problem, the trackpad stopped working completely and the whole thing froze.

Upon restart, the trackpad simply doesn't work (still doesn't) and I have to use a mouse to control it at all.

I reinstalled all of the BootCamp drivers, and it still doesn't work.

Any idea why this could be?

Thanks,

David

A:TrackPad Driver Randomly Stopped Working

Found a fix. Just needed to go to Device Manager, found two errors with the trackpad, selected "Properties" then "Resintall Drivers", selected the drivers from the list (in WindowsSupport folder) and then updated them and everything works again.

Thanks anyway!

I have an Asus laptop and  Asus external monitor, connection through HDMI,  Windows 8. 
During installation of v/drivers, Windows recognize the second monitor. However later, it keeps randomly switching between first and second monitor, with different intervals (from 20 sec to 20 min). I don't have this problem when i use Linux, so it doesn't seem as a problem with a cable. Thank you!   

A:Laptop is randomly switching between Internal and external monitor

Uninstall all video drivers over Device manager and select delete software before clicking OK, after please restart PC. After booting let drivers install itself then restart after finished, if it fails to install over Windows Update itself then download latest driver from Asus site and manually install.

I recently bought a new cisco e2000 router and had no problem connecting to it on all the devices in the house (about 10 of them)

Just now, all the devices in my room (ipod, netbook, phone, and laptop) lost a connection to the router and no matter where I am in the house none of these 4 devices can get a connection. I can see other networks, just not mine. They all worked perfectly fine before, and out of nowhere they stopped working. Other devices that were not in my room at the time of this 'wifi surge' still have a connection to the router.
The wired connection works and that's how I'm typing this right now...

Any suggestions?

Thanks,
Ray

A:Wifi on all the devices in one room only randomly stopped working

Hello laxman7,

I would start off with a Power Cycle. See if it helps, if not please move on to the next tasks.

You may visit Linsys site and see if there's a most recent update for you router even though your router is brand new.

Install and run Xirrus Wi-Fi Inspector from one of your wireless computers.
Double click the Xirrus Icon on your Desktop, Tap the Printscreen key on your keyboard, open up Paint then choose Edit from the Menu and select Paste, then SAVE it. Upload and attached the file here.

Please post an update.

Hey, so as the title suggests, I was just using my computer doing nothing special and randomly my USB ports disconnect then reconnect a few seconds after. I didn't think much of it, but then 1 minute later, the USB ports all disconnect and don't reconnect. I've restarted my computer multiple times, tried replugging keyboard/mice into different ports (back and front), have let the computer sit for a while then tried, but nothing is working and my USB ports just don't seem to work.

I fear this is a hardware related issue, potentially with the motherboard or a fried USB controller - none of my ports work with any type of USB input (microphone, keyboard, mouse)

I have heard of doing a CMOS reset or tinkering with my BIOS settings but am not sure how or if it will even be helpful or even what those are.

I'm really lost and my computer is basically unusable. I would genuinely appreciate any help possible.

Important Details:
-I've had my computer for around 2 years with overall crappy USB problems (ranging from ports that randomly stop working for a few days, to audio problems, to other random crap) so i feel as though my motherboard is not good
-My computer is prebuilt: https://www.newegg.ca/Product/Product.aspx?Item=N82E168...
-Right when all the USB ports stopped working, I had a video in the background and for some reason, my headphones through a USB to audio jack converter stilled worked and I could hear the video
-I think this may be an elec... Read more

Just turned my computer on, tried to load a gme put it did not detect the CD. I then restarted the computer, still no difference. Opened up my computer to see if there's any loose connections, although there was none I still took them out and put them back in, still no difference.

I went on device manager and this message was on the driver 'Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)'

How can I fix this?
