1
00:00:00,000 --> 00:00:06,180
if your computer just doesn't seem to be working correctly and you're out of

2
00:00:03,540 --> 00:00:10,380
ideas try this open up Windows device manager and look for anything marked

3
00:00:08,340 --> 00:00:14,940
with a yellow exclamation point you'll usually find them under a section called

4
00:00:12,240 --> 00:00:19,380
other devices but what does that mean and how do you fix it well in modern

5
00:00:17,340 --> 00:00:24,539
versions of Windows the operating system can automatically recognize most of the

6
00:00:21,960 --> 00:00:28,260
hardware inside or attached to it this is possible because each device you

7
00:00:26,400 --> 00:00:33,780
connect to your PC has a unique identifier built into it that tells

8
00:00:30,480 --> 00:00:36,300
Windows hey I'm a pixel 7 or I'm an RTX

9
00:00:33,780 --> 00:00:40,020
4080 or I'm a USB mouse Jiggler designed to make it look like my owner is working

10
00:00:37,739 --> 00:00:44,280
after Windows identifies what the device is it can install the correct driver

11
00:00:42,360 --> 00:00:48,239
which is a piece of software that helps the device communicate with your

12
00:00:45,780 --> 00:00:51,719
computer now some drivers are pre-loaded into Windows While others can be

13
00:00:49,980 --> 00:00:55,440
downloaded from Windows update meaning that you usually don't have to think

14
00:00:53,520 --> 00:00:59,460
that much about making sure you have the correct drivers so then what's the deal

15
00:00:57,780 --> 00:01:03,899
with these exclamation points well occasion generally this identification

16
00:01:01,260 --> 00:01:08,159
process can go wrong Windows also doesn't have drivers for absolutely

17
00:01:05,519 --> 00:01:12,420
everything and in some cases a device can just straight up malfunction leaving

18
00:01:10,260 --> 00:01:16,200
you with a rather cryptic error the simplest thing to do in these cases is

19
00:01:14,100 --> 00:01:19,799
to run a Windows update cycle to see if the system can fetch the driver

20
00:01:17,640 --> 00:01:23,640
automatically on the second try but if that doesn't work there are still a few

21
00:01:21,540 --> 00:01:28,979
other steps you can take if it's unclear what exactly the problematic device is

22
00:01:25,979 --> 00:01:30,840
say if it's labeled unknown device you

23
00:01:28,979 --> 00:01:36,360
can double click on it then click the details tab in the drop down menu select

24
00:01:33,600 --> 00:01:40,619
Hardware IDs then copy paste the result into a web search that should help you

25
00:01:38,520 --> 00:01:44,340
identify both the manufacturer of the device and the exact part number which

26
00:01:42,840 --> 00:01:48,720
allows you to go to the manufacturer's website download and at least attempt to

27
00:01:46,920 --> 00:01:52,740
install the current driver for it in most cases that should solve your

28
00:01:50,520 --> 00:01:56,100
problem but what if it doesn't if a missing driver isn't the cause of your

29
00:01:54,360 --> 00:01:59,399
error there are things you can do and we're going to tell you right after we

00:02:35,819 --> 00:02:41,160
of those situations where the oldest piece of advice in the book can also be

40
00:02:39,180 --> 00:02:45,420
the most helpful try taking that problem device which you've already identified

41
00:02:43,040 --> 00:02:50,519
unplugging it and plugging it back in you can either quite literally do this

42
00:02:47,400 --> 00:02:52,019
or you can do a bit of a soft unplug and

43
00:02:50,519 --> 00:02:56,940
plug-in by right-clicking the Troublesome Gadget selecting uninstall

44
00:02:54,420 --> 00:03:01,140
then rebooting your PC with the device plugged in to see if it gets recognized

45
00:02:58,800 --> 00:03:04,560
properly the second time around sadly though this tried and true method isn't

46
00:03:03,000 --> 00:03:08,040
foolproof and if you're still having issues you might have a setting

47
00:03:06,300 --> 00:03:12,540
somewhere that is interfering with your Hardware this is particularly common

48
00:03:09,720 --> 00:03:17,220
with USB devices so what you can do is try going into your power options from

49
00:03:14,459 --> 00:03:22,620
the Legacy control panel clicking change plan settings then change Advanced power

50
00:03:19,739 --> 00:03:27,420
settings under USB settings set USB selective suspend to disabled and reboot

51
00:03:25,379 --> 00:03:32,400
your system once again this could help the system properly recognize that Rogue

52
00:03:29,580 --> 00:03:37,019
device but failing that updating the firmware of your PC or of the device

53
00:03:34,379 --> 00:03:41,159
itself or updating your BIOS might get the error to disappear if it doesn't you

54
00:03:39,720 --> 00:03:47,220
might still be okay though because having one of these errors in device manager doesn't always indicate a show

55
00:03:45,000 --> 00:03:52,319
stopping problem there are some programs that can cause unknown devices to pop up

56
00:03:49,739 --> 00:03:58,500
these tend to be programs like virtual machines or vpns that install well

57
00:03:55,379 --> 00:04:00,720
virtual hardware and in some cases even

58
00:03:58,500 --> 00:04:04,260
after you've uninstalled these programs some of these entries can remain in

59
00:04:02,640 --> 00:04:08,640
there but with the dreaded yellow exclamation point of Doom in which case

60
00:04:06,420 --> 00:04:12,959
you can usually just uninstall them from the device manager window without too

61
00:04:10,439 --> 00:04:18,540
much drama if it's not a virtual device by this point it is possible in a

62
00:04:16,440 --> 00:04:22,139
probable that you have a device that either is no longer functioning

63
00:04:20,160 --> 00:04:26,520
correctly or simply doesn't have available drivers for your operating

64
00:04:24,360 --> 00:04:31,620
system this is particularly common when you move from semi-compatible operating

65
00:04:29,160 --> 00:04:35,940
systems like from Windows 8 to Windows 10 or from Windows 10 to Windows 11. you

66
00:04:34,199 --> 00:04:40,560
can sometimes Force the previous operating system driver to install and

67
00:04:38,220 --> 00:04:44,580
that can fix it but in other cases you might be just Plum out of luck and it's

68
00:04:42,600 --> 00:04:47,460
time for an upgrade if that's not the case though if you have one of these

69
00:04:46,020 --> 00:04:51,600
stubborn errors and you just can't get it to go away but your PC is working

70
00:04:49,800 --> 00:04:55,800
normally there is always the option of leaving it and growing into the type of

71
00:04:53,520 --> 00:04:59,419
person who's okay with that I mean our imperfections are make us special right
