Q: external display detected suddenly stopped working

Hi,

I have been searching in several forums but have not been able to fully fix this problem. It was fixed temporarily and failed again.
This the system I have:

HP TouchSmart tx2 tablet pc with Windows Vista Service Pack 2 (Home Premium) x 64 bit
AMD Turion (tm) X2 Ultra Dual-Core Mobile ZM-82, 2.2 GHz
ATI Radeon HD 3200 Graphics

I have been working for over a year with an external display Dell ST2310 flat screen monitor and working fine with the "use external display only" setting . From one minute to the other both screen went black so I forced a restart and again the same problem. I decided to manually disconnect the external display by unplugging the VGA cable from the laptop which automatically switched back to the main display as it would if I disconnected the display. When I plugged the VGA cable back in again the same issue both screens were fully black. I disconnected once again the VGA cable so I could change the settings in Windows Mobility. I plugged back in the VGA cable after changing the settings from "external display only" to "mirror monitors" and after playing for a bit with the Windows Mobility Center I got the external display to work back again to my regular settings: "external display only". This solution lasted for a day and now the main display works and the external display screen is fully black.

Solutions I have tried unsuccessfully:
- Changed VGA cables, still experiencing the same issue.
- Tested monitor according to Dell's specifications and monitor is working fine so the back-light is not the issue.
- Tested current monitor on a different computer and monitor works fine. Tested a different monitor on this computer and the same issue happens -black screen.
- Updated drives for ATI Radeon HD 3200 Graphics adapter and Generic PnP Monitor and Dell ST2310 driver.
- Uninstalled ATI Catalyst Manager and re installed it now as AMD Vision Engine Control Center.
- Verified that in AMD Vision Engine Control Center recognizes the external display connected.
- Uninstalled Dell ST2310 driver and re installed driver.
- In Display settings have tried extending the desktop onto the external display (second monitor)
Now this is what is happening and not sure how to fix it:
- Windows Mobility Center detects an external display even when the VGA cable is disconnected.
- When it detects the external display it sometimes detects it as DELL ST2310 and sometimes as Generic Non-PnP Monitor.
- Sometimes under 'Monitor' in the Device Manager there are several Generic Non-PnP Monitors listed in addition of the Dell ST2310 and Generic PnP Monitor.
- When the external display is connected the screen is fully black and does not work even after changing the settings with Windows Mobility or Fn F4. It seems that the VGA port needs to be reset but I do not know if possible or how!

HELP!!!

The title says it all. I'm very frustrated with this problem since I really need to connect my laptop to an external monitor for work. I've read and tried all relative topics in this and intel forums (e. g: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-920-can-t-connect-to-any-external-mon...), have done all steps mentioned (including firmware, bios and windows update, windows reset, ...) but the problem still persists. Apparently, most users that had faced the same problem been able to get it worked after installing "Type C Firmware for Windows 10 (64-bit)" or the BIOS update provided by Lenovo. I installed them successfully but nothing changed. I am sure it is a software issue since there is no sign of any hardware one (all devices are fine as device manager shows and diagnostics app found no problem). It was just working fine until suddenly stopped working (probably after some recent windows update). I would greatly appreciate any help.

Hey everyone, I've officially got THE worst luck with technology EVER.

Today, my Western Digital 500GB External HDD has stopped working. One minute it's working fine - the next its completely unresponsive. I deleted a music folder off the hard drive that wouldnt play and I dont know if that's been the cause of it to become unstable.

When I plug it in via USB I can feel the disk spinning inside and loading, but the windows sound does not play. About 2-3 minutes later I get the sound but it does not appear under Hard Disk Drives on My Computer. When I try to go into device manager it crashes windows explorer.

After a couple of attempts the name is now "Local Disk I:' and not even 'Elements'

After about 10-15 minutes of being plugged in the drive clicks and won't do anything else.

I REALLY need some of the work off the hard drive - It's so important to my second year at university.

Any help you can give me I will be eternally grateful. Call me a *******, but I usually back up my work via dropbox anyway but theres some bits I didnt back up yet and it's so important I get them.

I've looked at getting a universal drive adaptor but i've heard about data recovery software but there seem to be so many out there - If my hard drive isnt completely screwed could someone reccomend me one or give me some advice?

Thanks in advance.

Hello Would like to help but first what is the specific model of your PC? Dirty PC is not good to begin with. Upgrading from Windows Vista, amazed the upgrade worked, to Windows 10 is another snag in finding the problem. Suggest you try going back to Windows Vista and diagnose problem with factory operating system. Do you have HP recovery discs for Windows Vista? Maybe you can start there to find problem. Grzy

Hi there,

Well let me describe my set up first. I'm running a HP Pavilion dv2000 (Vista Home Premium) series laptop, and I have two external hard drives connected to the laptop through a 4-port USB Hub. The two I have are a Western Digital MyBook 1110, and a Seagate FreeAgent Pro. Both have an AC power supply and are plugged into a power strip. There have been no recent software or hardware changes.

After an automatic windows update my computer (running Windows 8.1 64-bit) suddenly lost connection to my external monitor. I tried connecting to the tv with another cable and it didn't work either.I uninstalled the latest update and it didn't work. I tried doing a system restore to a few days earlier and it didn't work. Then I updated the BIOS and it suddenly started connecting again.The problem is the next day it stopped connecting to the monitor again. This time I couldn't update the BIOS because I already had the latest version. And even if I could I shouldn't be having to do that.What can I do?

Hi,

I'm a bit kind of desperate now. I purchased a 2TB Western Digital Sata drive (WD20EARS) and an enclosure with USB2 and eSata interface (independent power supply). Everything was ok for almost 2 months till today it just suddenly stopped being detected at all.

I wasn't doing anything in particular when this happened. I remember I restarted my laptop around the time this happened (I do not remember if it happened before or after this). Any idea what could be wrong?

When I attach it with the eSata cable, nothing happens. With USB, I hear the beep that "something" was attached but then again nothing. Nothing at all in Device Managre or Storage Management.

Any ideas, please let me know... I'd appreciate it. Thank you.

Hi,

I have had an Iomega external hard for a year now and it used to work perfectly, until suddenly, my computer (Mac) won't detect it anymore.

When I turn it on, the blue light comes on and I can hear the disk spinning inside, but there is no trace of any external device connected to my mac. I've connected through USB and Firewire with no success. Going to disk utility, only my internal hard drive appears.

It simply just stopped showing up on my computer. Does anybody have any advice to get my hard drive working again?
 

A:Iomega External Hard Drive stopped being detected

Try a different usb & firewire port physically on your mac & try a different cable. If no dice try it on a different mac or even on a PC, see if the other computer detects it. many times w/ external hard drives the enclosure fails but the drive is ok. worse case scenario the enclosure is bad & you can remove drive to put in another enclosure, or the whole thing could be hosed. try this, post back. thanks!

Hey there, I have been using the same external enclosure for quite a few months now with no problems at all. I bought a new hard drive the other day (Western Digital SATA 80GB WD800JD), connected it to my PC like a normal HDD, and formatted it to NTFS using EASEUS Partition Master 6.1.1 Professional. I have scanned it for bad sectors via Partition Master, and ran chkdsk; all concluding with no errors.

I connected the HDD to the enclosure like normal, and it worked for a few times. Then last night I tried it and it didn't work. I was originally plugging it into the USB port located near the power button, so I tried using a USB port on the panel round the back, which kind of worked. It said it had to be formatted, so I tried formatting it but an error arose reading "The request could not be performed because of an i/o device error". I switched the enclosure off, waiting a few seconds, then back on again. The light was still on, and it seemed the same appearance-wise, but now it's not being detected in any USB ports on my PC. The USB connect "babum" sound plays, but nothing happens. It no longer shows up in any partition software and in Computer. Also, in Device Manager, it's listed under Disk Drives as 'USB Device', with its status being "This device is working properly."
I connected it to a laptop I got my hands on, and the sound plays, with it not being recognized. It runs Windows the same Windows OS version too, and whe... Read more

It's my experience that enclosures are less reliable than the HDs that we put in them ..
Assuming you get a good brand of HD .. (WD Black series are my favorite)

Sounds like you've tried every thing except try the HD in another enclosure.
For this reason .. I always have a spare enclosure.

Okay, this is the weirdest problem I've ever hard with computers. Here's what happened:

1. I had a few years old Pentium D 2,8GHz processor running on Asus P5VDC-X mobo. PQI 566MHz DDR2 and GF 7600GS 256mb PCI-E, 350W power.
2. I updated the mobo to Asus P5L-MX to support faster PCI-E cards. Everything worked fine, despite the processor ran too hot (58C on high use)
3. Because of the overheating I replaced the thermal paste but it had no effect on the temperature.
4. I thought I used too much paste so I replaced the paste again.
---
5. Bang, no video when I turn on the computer. I tried taking off everything part by part but nothing worked. It didn't work even when I only had processor and used the integrated graphics port. Tried resetting the bios too.
6. Nothing worked so I put back the old P5VDC-X and it worked like charm.
7. I thought it was logical that the problem was caused because of the mobo so I bought a new one, Asrock G31M-S.
8. No video... Did the same steps to this one too. It also had integrated gfx but it didn't work either.
9. The old P5VDC-X still works.

So I have no idea what's causing the problem. Is it the CPU? Mobo? PSU? RAM? I have no speaker on my case so I can't hear any beeps, but it won't start loading the OS from the hardrive and my USB mouse won't turn on. Tried using a differen't monitor too.

The main point is why it stopped working suddenly on new mobo's but still works with the old P5VDC-X? A... Read more

Two new motherboards tells us you made the same simple install error in both of them.
Tell us more about power supply, memory, cable.
Did you make sure the memory was correct for both new boards, and what is the memory on the old board. Would also like to know the power supply and other hard ware.
What happens with the most basic, simple install. Does everything light up?

If you used the same hard drive with the same Windows install on the two motherboards, that is the problem. Windows has detected that you have changed the motherboard and will not operate unless you reinstall Windows on the drive on each new motherboard... One install for each motherboard.
My guess is that you will be fine if you change hard drives or do reinstalls or repair installs of the Windows on the new motherboard.

Hey guys,

So I put together a new PC running Windows 10 Pro around 3 months ago and everything was working perfect till 2 days ago when my mic suddenly stopped working. I use a Steelseries Siberia V2 headset and the headphones work fine, but the mic is not picking up any noise at all. I tried plugging in both the back and front ports and my realtek always detects that a mic has been plugged in, but it simply won't work. I thought maybe my mic got busted so I also tried using an A4 Tech headset that I had lying around in the office but it has the same issue, the mic won't work. I looked around online for possible solutions and tried the following with no luck:
Ensured the mic was set as the default device and that its volume settings were maxed out.Tried disabling all sound effects (noise suppression, acoustic echo cancellation etc).Uninstalled all audio drivers and reinstalled the latest realtek drivers on my motherboard's webpage: GIGABYTE - Motherboard - Socket 1151 - GA-Z170MX-Gaming 5 (rev. 1.0) Uninstalled all audio drivers and reinstalled the latest realtek drivers on realtek's own webpage: RealtekUninstalled all audio drivers and let Windows auto-install drivers.I even uninstalled all realtek drivers and tried using the standard "high definition audio device drivers."

Hi all,

I run a network at home, 2 computers, both running xp. One connecting directly to cable broadband modem (computer 1) with the two computers linked by a single crossover cable. For the past year or so I have happily shared the internet connection as well as the printer and numerous files but today when I booted them up computer 2 - the one not connected to the modem - simply gave me a "Limited or no connectivity", I'd had the problem before and had in the past easily fixed it by repairing the connection however now it simply hangs on renewing ip address.

I've tried restarting computers, disabling and enabling connections, nothing I do seems to work. Any help is greatly appreciated and any more information I need to provide just ask.

Not to be harsh, but when you get it working again thru what ever means you might have to do, make an image on a flash drive or what ever you choose and then, if the SSD has failed completely, install a new one and use the image to bring you back to the time of your last backup.

So im not sure if im posting this in the right place. But i see no category for devices. Aswell as i feel like this is a windows related issue.

Anyway. I have an msi gaming G series laptop. I turned it on today to find out my [n] key no longer registers?. It is only my [n] key in lowercase. The key worked fine yesterday, i didn't spill anything into my keyboard or anything like that and everything else works fine. The key works if i hold shift ,i get a capital N, if i use caps lock however it doesnt work either. But if i use caps lock and hold shift and press n, i finally get a lowercase [n]. But this is the only way to get it to work. Ive checked for windows and drivers updates. Both updated, restarted multiple times, tried toggling languages. Still doesnt work. If i make a new user account, it works perfectly on that account. So for some reason only on my account will [n] not register. Ive asked all my friends who are tech genius's and even they are confused on how this is possible.
Please help this is very frustrating due to the degree of impossibility.

Good morning everyone, and a Merry Christmas!

I'm going to try to make this as brief as possible, while still including every detail I possibly can.

Today I received a few cool gadgets for Christmas that I wanted to install on my PC. I realized I was short on USB slots, so I tried to install a secondary set of USB slots. I plugged it in wrong twice in a row, due to me misreading my motherboard. After a few restarts, my computer wouldn't boot. I attempted to clear my CMOS, which didn't help. I then turned off my power supply's switch, then turned it back on. After I did this my PC booted, but I was fronted with a boot screen that said the CMOS settings were wrong. I was confused as to what this meant, and my options were F1 to Bios, or F2 to default settings and continue. After booting, my Razer Deathadder quit working. Now, at this point, I'm not sure why exactly I did this, but I reinstalled Windows. I am using Windows XP Pro -32 bit. After reinstalling all my drivers, I realized that NONE of my USB ports were working. My keyboard, mouse, webcam, nothing worked. I updated my Windows, BIOS, drivers, everything is new.

In the screen for Hardware, all my Root USB kits have exclamation points, and it says they aren't functioning properly. I have NO idea what the hell is going on, and if anyone has any ideas or comments, please please share them with me.

Hi,

I've been using the Microsoft Wireless Broadband router (MN-500) to connect to the internet. This afternoon, while I was away, the wireless connection was suddenly lost. The internet is fine, because when i plug my computer directly into the router (via ethernet), i am able to access the internet. However, the router does not seem to broadcast a wireless signal for the LAN.

I've reset the router, both manually and via the software and reconfigured the network. After this process, the Wireless Network sometimes appears momentarily in Windows...but the connection drops before it can connect.

All the lights on the router light up as normal and it indicates that both the wireless LAN and the WAN are working properly. I have no idea why I can't connect to the network wirelessly though...

Any thoughts?

Firstly I apologize if this is in the wrong forum. Secondly some background information, my Sony Vaio laptop awhile back had it's display burn out so that nothing was appearing on the screen. I fixed this by connecting an external display to it and I just used it like that and everything was working up until recently. My laptop was in desperate need of a format so I did just that, I put a clean install of Windows 7 Ultimate x64. After the format was complete I found that I was unable to connect my external display thus I am unable to use my laptop. The only way that I can see what is going on my screen is shining a flashlight into it and I already tried everything to fix it, I installed all the necessary drivers, I checked if it was the display that was not working, I clicked detect on the display settings, I clicked Win +P, Win + X, Fn +F7, etc. No matter what I try I cannot get it to connect. I am completely stumped. So please if you have any information that could help with my problem it would be greatly appreciated.

A:After format, external display not detected

If you can possibly see anything on the laptop screen you could try pressing the Windows Key & the P Key at the same time & select the external monitor, which on my computer is the right hand one. If you cant see anything on the laptop screen you can use the left & right Arrow keys in the above method to make the selection.
It's possible your access to the external monitor is switched off so using this method may switch it on.

External hp 2009m display not detecting connected Inspiron 7547 64 bit.  I reinstalled an older version of display driver last fall because it stopped working after Windows 10 updates.  It seems to have reverted since as there was a bios update
this weekend and now my monitor keeps going to sleep mode. How do I get it to detect the monitor again?

Hello,  I have an Envy17 and yesterday the touchpad suddenly stopped. No warning no nothing. It was working fine and then I closed the laptop for a few (did not shut down all the way) and the next time I opened it (bout an hr later) the pad was dead. Tried uninstalling and reinstalling the driver, numerous re-boots and installing computer/windows updates. Still does  not work. Have tried to double click the opper corner in case it was accidentally turned off but still nothing. When you go into settings, it says it is working properly. Anything else I can try?  ThanksLacyayn

I have a duel monitor setup where one was plugged into HDMI and the other into VGA. Both were running off of my NVIDIA graphics card (i also have Intel 4000 Graphics which came with my processor but is not in use).
When playing a game - my HDMI monitor just shut off. My VGA continuing to work.
I have tried many things such as reinstalling drivers but nothing has seemed to work. My Intel 4000 Graphics are failing to work also. I am yet to look inside of my PC to see if anything has moved out of place.
I've tried googling and I've found nothing of use. If anyone has a solution that would be great! - P.S I'm new to the forums

A:USB ports suddenly stopped working!!

Tell us the brand and model of computer, whether a desktop or a laptop, and the location of the usb ports... whether front or back, or whether we are talking about a powered external hub, or a multimedia box in the middle of the computer which has a 9 in 1, 15 in 1, or similar memory card reader with USB ports.
Are the USB ports built into the case, or on a pci card slot on the back of the computer.
Generally, USB ports do not fail. There are a few times when they do because any electronics made with chips, thyristors, and printed circuits can fail. But USB ports are among the most rare of failures... except when you are using multiports.
On inexpensive USB connections, they all share one connector... If you have four or five ports on one connector to the motherboard, then those in use will reduce the power that is accessible on lower quality units.

Last night I was doing my usual gaming on my PC when I started getting popups about USB drives malfunctioning. I didn't think much of them at the time. Later on during the night, my USB mouse stopped working. I didn't think much of it and I switched it to a free port. It started working again. Then trouble started.

I plugged my headset into another free port (it had been plugged into my Xbox 360, it was working fine beforehand) and started to watch an episode of a TV show. The sound was horrendous. It wasn't the file and it was not my headset, as I tested it again on my Xbox and was working fine. I switched USB ports. It didn't work. Then my mouse stopped working, and my keyboard. Funnily enough, my USB phone charger still showed it was charging my phone, and it still does right now.

I restarted my computer, and at the POST screen it said a keyboard error had occurred or one was not connected. When I start my computer with the keyboard plugged in, the lights flash and the backlight comes on (it is an illuminated keyboard, so the blue lights beneath the keys work for some reason) but none of the keys registered. I had to dig out an old PS2 keyboard to get my computer to even get past the POST screen.

I did some reading around and saw a simple fix of turning off your computer and unplugging it from all power sources, so I left it unplugged for 10 hours while I was at work with the CMOS battery removed. I got home and plugged it back in with just the keybo... Read more

Hi guys, I know this is my first post so I'm sorry that it is to ask for help.

I own a set of Turtle Beach X11 headphones that I originally bought for use with my 360. However, I discovered I could use them for PC too so I now use them primarily for teamspeak and such. To start with I had no problem setting it up: Just plugged in the USB lead, mic lead into pink jack, audio into green jack and everything worked fine without the need for drivers or any set up.

Everything has worked fine for weeks but all of a sudden my microphone is no longer detected by my PC. The headset speakers work fine, I can hear other people but they cant hear me. The weird thing is I can hear myself speak through the speakers when i speak into the mic, so clearly it isnt a hardware issue but something else has changed by itself.

The only thing I did before the mic stopped working (Aside from use teamspeak like normal) was to install hamachi and to try and use the STEAM voice chat feature, out of curiosity. I first assumed that one of these had maybe interfered so I did a rollback but that didnt help.

I have tried all the basic stuff and am pretty sure my sound card drivers are up to date that I know of but any help would be very much appreciated.

P.S. I have an ASUS motherboard with a built in sound card. Here is a dxdiag just in case it helps:
UPDATE:

I bought a cheap plug and play mic that just plugs into the mic jack to check if a new one would work. Unfortunately it doesnt, same... Read more

On a previously fine PC, I noticed the usb cable for my Palm Pilot had fallen out (so that's why I couldn't connect to it!)

So, I foolishly plugged the usb cable in. The screen froze, had to press reset to reboot.

On rebooting my ISDN adaptor had a cross on it, indicating it wasn't enabled, it was IMPOSSIBLE to restart it. So I deleted it in device manager......it wouldn't delete "the device has failed to respond in a timely fashion".

Then I realised all USB connected peripherals were not responding, ie isdn adaptor & printer! Everything I've tried has failed, switched ports, cables, nothing is detected when a usb cable is plugged in. So I was stuck with no internet connection, until I reinstalled my old PCI modem. Please guys, any advice would be much appreciated. I'm concerned something I did plugging that cable in has fried all my usb ports on my mobo

We've got two PC's that are connected to the net, mine and my father's. I hadn't done anything to modify either hardware or software configurations, however, my Internet stopped working on my computer. My father's remains working. Putting it directly from the cable box to my PC works, changing the port in the back of the router does not, however my father's will work on any of them. Obviously the only thing left would be the cable connecting my network card to the router, however, I've tried another cord I had laying around (which was working the last I tried it) and it still doesn't work. I've tried ipconfig /release and /renew numerous times on the varying configurations that I've tried. No luck.

Any ideas? I don't really want to go out and buy another network cable if it won't work out for me either.

Lately every time I try to connect a known working USB device, like digital camera, thumb drive, web cam, etc. I get a pop up window that says the device is not recognized. I have a printer plugged into a USB port, and it works, although I did have to reinstall the driver for it recently, because it too get the same error.
Is there a driver or drivers I should reload? What should I do to determine if it's really a hardware (port) problem? Devices will work on other computers, just not this Compaq desktop, 1.6Ghz, 2GB RAM, roughly 3 years old, XP SP3

My audio has stopped working for Windows and Gaim, but Winamp and various games are still fine. I've reinstalled the drivers many times and uninstalled every possible audio device, but I always end up with the same thing.

In Winamp's WaveOut plugin, the first device is messed up.
In DirectSound everything is fine.
In Windows' sound manager, the preview button is greyed out.
I think this means there is something wrong with my wave settings, I just don't know how to fix it. Hope the pics help, let me know if you need more info.

I have a 3 monitors setup. One is plugged in via HDMI, one DVI and one DisplayPort. I just restarted my PC and the monitor with DisplayPort has stopped working. I tried restarting again, nothing. If I try to enable it in the display settings, the computer freezes for a few seconds, then I get an error that says "The display settings could not be saved."

Here's a video of the freeze thing; https://streamable.com/8gg8o

I tried unplugging all monitors but the DisplayPort one, but it still doesn't work. I tried unplugging and replugging, nothing. When I ONLY plugged the DisplayPort one, the monitor kept saying "DisplayPort: No signal" on and off and on and off. Any idea?

Both of my CD ROM drives on my computer have stopped working. I have gone into the device manager, and both devices have the yellow question mark next to them. I uninstalled both devices and restarted the computer. It recognizes the hardware on startup and attempts to start them, but then I get a message that says there was an error with the hardware installation. The Device Status says: Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)

I have performed a registry mechanic to see if that would help, but nothing.

Any thoughts?
