00:05
so moving from the general to the specific
00:12
this is Look at some items were gonna walk through
00:15
ah, hierarchy of some items to look at.
00:18
Ah, and all these air about identifying the problem.
00:21
So in hardware, right
00:23
things to look for on this list. I'm not going to read everyone limber to get the idea.
00:29
Doesn't have power. Is a system dead or alive?
00:33
Is the bios posting codes?
00:36
And that's that beeps you here If if you hear a system that's beeping oftentimes, where if you listen for it, you'll find the beef has a pattern.
00:44
It may be two shorts and a long
00:46
or three longs in a short.
00:49
Or it may just be that it beeps continuously
00:53
the
00:54
the
00:55
the
00:57
If you know
00:58
you can go look it up for the most.
01:00
Most instances, you can act fine
01:03
that those relate to a specific troubles reading issue. It will say the memories bad. It'll say the CP use overheated and the different beefs and the different patterns have
01:15
different root causes,
01:17
so you can solve a lot of problems that way. Look for indicator lights, anything that's not green. We're supposed to be green
01:23
hardware noises.
01:26
Um,
01:27
years ago I worked on a number of servers. They all had the same hard drive in them,
01:33
and those hard drives had a systemic problem that when they got about 3 to 3 and 1/2 years old, the bearings would start to go out. So you'd walk by and you'd hear this burying, just
01:42
whining at night.
01:45
And we finally got to the point where we didn't wait for the drives to fail. When we heard that noise, we knew what it was. And we replaced the drives in advance
01:56
and the drive's will still under warranty. So we got them all for free.
02:01
If if there's smoke,
02:05
this could be a sign of a problem.
02:07
Overheating smells things that aren't supposed to be there
02:12
in a written device. Failures
02:15
is a really intermittent Or is it just a pattern you haven't discovered yet? Sometimes they're truly random.
02:21
Other times they happen always right after
02:24
Patch Tuesday, or they'll happen always right after,
02:29
uh,
02:30
power outages. They'll happen always right after some other event.
02:34
So look for that.
02:38
Uh, one of the interesting ones is you'll turn a computer on and the family come on.
02:44
But the system will never boot.
02:47
Well, that's an indication, right, because there are two different power sources inside of power supply. Once 12 volt
02:54
and one's five volt,
02:57
the fans were out on the 12 volt side and the rest of the motherboard boots on the five old side.
03:04
So if you have fans running in the rest of system not booting,
03:07
I'll be back in there with a multimedia checking to see if the five old side is gone.
03:14
Boost me to death or system lock ups. Do they occur after launching the same map every time where they just totally random
03:21
Did they occur only
03:23
after the system's been on a long time? Who could
03:27
speak Thio cooling fan on the CPU? That's failed
03:30
and the CPU is overheating and locking the system up.
03:34
And last but not least,
03:36
log files were there for a reason. You might actually read the long files and see if it keeps telling you
03:40
what the error is, right before the system does whatever it does wrong.
03:46
And it's got this log in ID of three weeks of
03:49
file problems.
03:50
If you just find them
03:53
this Dr
03:55
they're read, write failures slow performing. So are they making loud clicking sounds right?
04:02
Is it a boot failure?
04:04
Are the drives 19 being recognized when it comes up to, say, drives not recognized, right is not available
04:11
or does the boot to the drive in The drive itself doesn't have the Apple case. And you expected
04:16
Did you get all the way to the operating system
04:18
boot up and say, Oh, s not found
04:23
Raid not found.
04:28
All those have different solutions.
04:30
And to help identify the problem that will help identify the solution
04:38
video.
04:41
Um,
04:42
sometimes he
04:44
well, this will happen.
04:45
People will replace a monitor
04:47
for the replace a video card and not tell the operating system They've changed it.
04:53
So have the wrong driver in the monitor of the wrong driver in the video card
04:57
and
04:58
the booted back up again and it won't work.
05:00
And windows you can hit hit f Hey, you go into,
05:04
uh,
05:11
VD a mode.
05:14
Or you can set it up with just a straight 806 100 default VD a driver that every card supposed to support. If it works, then that won't work at a higher resolution.
05:25
Then maybe your new card has resolutions higher than the monitor can support. And all you have to do is just tweet.
05:31
The resolution
05:38
Is a color patterns incorrect or the images *** or it flickers Or Scott. Random color discrepancy is a lot of time. If you're running a V G a cable, just shaking the cable connections will tell you that there's some pin that's not connecting right.
05:54
So things like that
05:58
Networking,
06:00
No connectivity,
06:01
no connectivity. How much? How much? How much is no connective ity?
06:05
If the nick doesn't have a light on the link light,
06:10
then you have absolutely no connective ity.
06:13
If the link lights on but you're not getting an I P address,
06:16
then it could be a connective ity problem or a D h c P problem.
06:20
Ana people address a P I. P. A.
06:26
Is,
06:27
you know, only, you know they're having the people address. If you get 1 69 dot to 54
06:32
dot anything got anything
06:34
that's automatic private I p addressing automatic private I P address and only comes on when a system set to get a type E V a D. A, C P and the D H CP never shows up
06:48
If you see 1 $69 to 54 than address, then you definitely know you haven't addressing issue.
06:57
I p conflicts. If you get a notice of an I p conflict,
07:00
then he just somebody else has the system manually set
07:03
or the D c. P server has been rebooted and lost identity for who? What addresses had already passed out
07:11
has passed the same address. How twice? Where? Something like that.
07:15
In a wireless world, if you have no r f signal of using, like no bars or one bar on your wireless, that could be the walk. Why? The wireless network is dropping in and out.
07:29
Operating system errors. Blue screen of death be S O. D.
07:32
Did you get it on Boot up. Where did you get it? After the system was already booted and running?
07:36
Did it never boot up it all? You got a boot failure?
07:41
Did you have an improper shutdown?
07:44
There are still people who will take
07:46
Maura laptop than the desktop. These days. There are still people who will just take the power button and jam it and drop the system.
07:54
It was just hold the button down until the system shuts off.
07:57
What that does often isn't lease applications have open at least data hanging
08:01
in RAM that didn't give written to the disk.
08:05
It can leave a disc in a corrupted state. So all kinds of reasons not to do
08:09
forced shutdowns
08:13
you could be getting message on missing DLL Missing files
08:18
Service's have failed to start
08:22
compatibility errors.
08:26
System the boots a safe boat continuing doesn't boot to normal mode.
08:35
Security errors.
08:37
Browser errors. Browsers can include pop ups When you're not, when you don't expect to see them re directions, you're going to one website and you get redirected to another website. Or maybe it doesn't catch it all.
08:52
You could have security alerts.
08:56
You could have smoked performance for the PC locked up. And you think it's a hard world problem when actually, it could be a security problem because it could be an infected machine.
09:05
I'm always suspicious when Windows updates. Don't update.
09:11
The reason I'm suspicious is because some viruses, some malware, will block windows updates just to make sure that our doesn't get turned off
09:20
toe. Always identify a reason when Windows updates fail.
09:26
If you're getting a lot of spam, maybe that's an indication that you're,
09:28
uh,
09:31
spam filters aren't working. Or maybe it's an indication that your email accounts have been compromised.
09:39
Renamed system files or duplicate system files
09:43
could be an indication of infection.
09:48
Disappearing files is never a good thing. Not unless you made them disappear yourself.
09:54
System access denied to use the same username password you've always used and now you can't get in. It could be someone's compromise to Captain Changed. The password
10:07
Matt tops is their dim flickering or have no display.
10:11
If you think about it right, you don't see the connection between
10:16
the motherboard of the laptop and the screen of a laptop, but it's a little tiny ribbon cable inside the hinges
10:22
that doesn't sound like a great place to make a streaking, long lasting connection.
10:28
So often.
10:30
That can be what makes a laptop, um,
10:33
image fail if the image is dim, but you can see it if you turn strong enough light on in the room.
10:39
Laptops actually got a backlit images. Actually, I'm long
10:43
then
10:46
tube.
10:46
That's a light at the bottom
10:48
that shines up on behind the pixels and gives the light that shines through the screen and shows the colors.
10:58
If that light goes out or the connection of that light goes out,
11:01
you can might be able to see the rest of the images up there. But there's just like a little faint ghosts in the dark.
11:07
And that can't be an easy fix.
11:09
It was just the light itself that could be a relatively inexpensive fixed
11:18
printing and printers.
11:20
Are you having gaming image issues? Streaks, ghost fades off color.
11:26
One of the simple solutions to find out?
11:28
Is that a problem with the printer? Or is that the problem with print drivers? Or is that a problem with
11:33
what's being sent to you?
11:35
Is almost all printers have a diagnostic test image?
11:39
If you go to the printer console and bring up print that diagnostic test damage?
11:43
If the test average prints perfectly,
11:46
then the print mechanism itself is working.
11:50
Is this test Chambers Prince Bad?
11:52
Then, until you get a test and Mr Print well, don't worry about what's coming from the machines. Get the test image to print, right, and then see if it fixed everything else.
12:01
Your tone is not fused to the paper. Toner is literally plastic powder
12:05
and being fused to the paper means is a hot roll with actually melted into the paper.
12:11
So if you could take the toner, wipe it off with your hand. You get black all over your hand is not sticking on the paper.
12:18
The Fuser problem is
12:18
normally the culprit
12:20
diffuser.
12:22
Maybe the only heating element's gone bad in the Fuser.
12:26
If paper's creased jam not feeding,
12:31
look for mechanical errors. Look for having the wrong paper inside.
12:35
One other thing you can do is take a fresh ream of paper.
12:39
Drop it in, see if that fixes the issue.
12:43
If that doesn't fix years, you take that ream out,
12:46
turn it over, put it right back in
12:48
paper, has a natural curl in one direction,
12:52
and sometimes you'll find out just turning the paper over. Fixes it
12:56
if you're getting garbled characters,
13:01
especially if you get
13:01
pages and pages and pages. Garbled characters. When you thought you were gonna print a picture,
13:07
I thought you were gonna print a document.
13:09
He realized that everything has sent in. The printer is ones and zeros.
13:13
Everything incentive the printer and can be read as asking text.
13:18
If you have a driver problem
13:20
or If you're sending postscript to a PC l'm interface or PCL to a postscript interface,
13:26
it may just not know how to decode it and may instead just be trying to send it out as text, even though it's supposed to be a photograph
13:35
hitting no memory errors. Maybe there's a bad memory module. Or maybe your print is just being overloaded by too many print jobs.
13:43
I have seen no memory errors from people who tried this in
13:46
large PowerPoint files because of Power Point filed its small on your desktop,
13:52
his huge when you tried to credit,
13:54
because it has to actually account for all the car on all the page areas and can be 100 200 megabytes from or to print one
14:03
her.
14:05
If you're unable to solve printer or have printer access denied,
14:09
that could be a privilege and rights issue.
14:13
And if the print herself has failed, be sure to look on the printer for error codes.
