Welcome to the county a A plus 2 to +0-1001 module one.
00:06
Today's lesson is lesson 1.9. Monitoring
00:10
Monitoring hardware in the BIOS I'm your instructor, Bill Price. Let's go and get started,
00:16
Okay, for today's lesson, let's go over our lesson objectives. First, we're gonna talk about temperature monitoring the heat inside the case and monitoring those those temperatures. Next, we're gonna talk about fan speeds and what we can do with fan speeds and controlling that or monitoring that,
00:32
um, we're gonna talk about being intrusion, detection and notification.
00:37
Finally, we're gonna come up to voted and the voltage in your system and monitoring that and our last item that we're gonna cover in this lesson would be the clock in the bus speeds. So let's go ahead and get started.
00:50
Temperature monitoring. Um, we can't stress enough that it's very, very important that you keep track of the temperatures inside of your computer. It's very, very important. The reason why it's important is because of potential damage to your components,
01:06
the components on the board or other devices like the CPU, graphic video cards
01:11
and other devices that's mounted or around in the system unit itself.
01:18
Symptoms of high temperature in your computer. You experience a sudden shutdowns, constant reboots or restarts, or your system may not boot it all,
01:27
or you may boot, but you may see alarms are errors in bios, and we covered that earlier. In another lesson, you'll see Arab post codes and post it will say in temperature alarms and so forth.
01:41
All of these symptoms are telling you that your computer is running too hot and something needs to be done as soon as possible.
01:48
So monitoring the temperature on the motherboard. Ah, lot of the mother board manufacturers have a lot of different utilities. They pretty much I'll do the same thing. They monitor the heat that's on the board as well as in the system. Now, motherboards have built in heat sensors to monitor the components. Like I said
02:05
on the board and in the system, So you get the best of both worlds. You can monitor the board itself, as well as the ambient temperature around the board inside of the case.
02:15
Now, some models have options to reduce the CPU speed to lower the CPU temperature. If you're running heavy loads or running slightly. The normal loads in the CPU is task very heavily. You can go into the BIOS and make adjustments to throttle that back to kind of keep the system cool.
02:35
Now the two components that generate the most heat would be the CPU in the graphic video cards in heavy gaming systems or just heavy use or developed design systems. These two components work the heaviest. They carry the heavy load, so therefore they generate the most heat.
02:53
Now again, over heating systems can cause component damage, So it is important imperative that you regulate your heat, watch your heat, monitor heat and make changes as soon as possible so you don't damage the components in your system
03:10
now causes for a computer heating. These are some causes that we have seen blocked air vents. If there's not a Rh flowing inside the system unit case, it's a lot of heat is not cooling the components off. Heirs must circulating, so, therefore, that's going to generate heat.
03:29
Blocked air vents, as you may know,
03:30
comes from one of many different reasons. It could be dust buildup. It could just be the where the unit is positioned under the desk and has no airflow. Those system units computers need airflow to keep help. Keep it cool
03:46
of the cooling. Opponents or fans are not working or not working at all, or someone working. You have to make sure that those fans are running properly. Physical looking at the fans that could be dust buildup. It could be running slow because it's funk failing. So you wanna
04:05
picture eyes on that
04:06
that device and make sure it's running correctly.
04:11
We've also seen heat sink Finn issues. The fans on the heat sink, which is on top of the CPU, could be crypt and nodding, not letting air flow from the CPU on cooling that c p off. So again, that could be physical damage with that device.
04:28
Thermal paste issues the thermal pace between the heat sink and the CPU.
04:32
It could be thin or none at all. The thermal pace help dissipate the heat from the CPU, so that's something you need to be checked as well. And also malfunctioning components, congenital rate, excessive heat in their operations. So all of these factors could generate a lot of heat for the system unit.
04:53
So let's talk about fan speeds,
04:56
fame, speeds, bios, monitoring the fan speeds. Some features will vary by model comin speeds that you may see or settings that you may see in the BIOS would be a standard a turbo, a silent or manual all of these air controllable
05:11
in the bios. And you'll see these Maurine. The newer Yueh Fei bios is
05:15
versus the older legacy systems.
05:19
Now here we see another ah version of the U F I where you can control as far as the fans speeds here, and this is in the gigabyte. MoMA The board again check your motherboard manufactured for details here because it will vary in the different features in
05:35
of components that you have available as faras. Monitoring those fans speeds and adjusting advance beads.
05:43
Let's move on to intrusion detection. Since the early onset of he sees, there's always been a form of intrusion detection on the case and reason. What this would be important is you want to know if someone is tampering with your system. You want to know if
05:59
someone has went into the case in May, have caused damage maliciously or for whatever reason that kept that case has been opened
06:06
just like an alarm on your house or your car. You want to know if someone's inside of that? So the same thing with a interesting texture action on the PC he wanted on that case has been open or by unauthorized individuals.
06:19
So the intrusion detection switch detects intrusion to the interior of the system unit case, and it provides an alert that the case has been open and this could be in the form of a postcode that pops up when you boot up the computer. You see a post Ercole intrusion detection
06:36
that had been a notification or pop ups along those lines,
06:43
and here you can see an advanced system. The U. M U F I difference settings for this as well. So it again it varies. Depending on the bio is that you're having your system
06:55
voted monitoring very, very important monitoring the voters of your system. Like I said, it's critical components can fail or be damaged because of improper voltage. If it's to lower voted JJ over appear to time that could degrade the components.
07:12
If it's too high voltage, of course, we know that it may burn or zap the components.
07:17
The CIA voted of the CPU and regulars can be monitored in the BIOS. And here you have an example of the oasis you if you f I bone bios utility and the monitoring of the vote. It's here
07:33
clock and bus speeds. In some Biles versions, you can monitor the speed of the CPU.
07:40
Um, over clocking is what we've learned in the earlier lesson of 1.6 that were running the CP. What higher speeds allows you to make adjustments or change the clock speed? You can verify that your clock speed is running, according to the manufacturer details here in the BIOS.
08:01
OK, so let's review some of the items that we went over. So we talked about the temperature monitoring, and we stress as far as how important the temperature monitoring in is in your system, it wouldn't cause improper temperatures and the damage.
08:16
We talked about fan speeds and we looked at different examples. Those fans speeds either changing the van speeds and monitoring across different bios utilities. We talked about the intrusion, detection and notification, and how that looks we talked about voltage. Vote is very important, making sure you're monitored of Oh jeez,
08:35
voted in your system unit system.
08:37
And finally we rounded off and finish talking about the clock in the bus speeds and monitoring there. So a lot of different monitoring features in the BIOS the BIOS is, is again. It's the central brain of your computer center is a lot that the BIOS
08:56
does and can do. So there's a lot of monitoring
09:00
what that happens as well. So it's outside of all of that, you know, as you're running your operating system and doing everything with your computer again. The BIOS is critical to all of that, because that's where all the the hardware and everything talks to sew. It monitors everything like the command center from the background.
09:16
Okay, so that's all for today's lesson.
09:20
Um, I hope you enjoy this and got a lot out of it. I no idea. So we will see you in the next lesson.
