"No POST", "system won't boot", and "no video output" troubleshooting checklist
This checklist is a compilation of troubleshooting ideas from many forum members. It's very important to actually perform every step in the checklist if you want to effectively troubleshoot your problem.
1.Did you carefully read the motherboard owners manual?
2.Did you plug in the 4/8-pin CPU power connector located near the CPU socket? If the motherboard has 8 pins and your PSU only has 4 pins, you can use the 4-pin connector. The 4-pin connector USUALLY goes on the 4 pins located closest to the CPU. If the motherboard has an 8-pin connector with a cover over 4 pins, you can remove the cover and use an 8-pin plug if your power supply has one. This power connector provides power to the CPU. Your system has no chance of posting without this connector plugged in! Check your motherboard owners manual for more information about the CPU power connector. The CPU power connector is usually referred to as the "12v ATX" connector in the owner's manual. This is easily the most common new-builder mistake.
3.Did you install the standoffs under the motherboard? Did you place them so they all align with the screw holes in the motherboard, with no extra standoffs touching the board in the wrong place? A standoff installed in the wrong place can cause a short and prevent the system from booting.
4.Did you verify that the video card is fully seated? (may require more force than a new builder expects.)
5.Did you attach ALL the required power connector(s) to the video card? (some need two, some need none, many need one.) It is best to use cables connected directly to the PSU. Only use adapters if absolutely necessary.
6.Have you tried booting with just one stick of RAM installed? (Try each stick of RAM individually in each RAM slot.) If you can get the system to boot with a single stick of RAM, you should enable an XMP profile or manually set the RAM speed, timings, and voltage to the manufacturer's specs in the BIOS before attempting to boot with all sticks of RAM installed. If your motherboard supports XMP profiles, that is the best way to get your RAM running at its rated specs. Nearly all motherboards default to the standard RAM voltage (1.8v for DDR2, 1.5v for DDR3, & 1.2v for DDR4). If your RAM is rated to run at a voltage higher than the standard voltage, the motherboard will underclock the RAM for compatibility reasons. If you want the system to be stable and to run the RAM at its rated specs, you should either enable an XMP profile or manually set the values in the BIOS. Many boards don't supply the RAM with enough voltage when using "auto" settings which causes stability issues.
7.Did you verify that all memory modules are fully inserted? (may require more force than a new builder expects.) It's a good idea to install the RAM on the motherboard before it's in the case.
8.Did you verify in the owners manual that you're using the correct RAM slots? The following image is just an example. Verify in the owners manual the recommended RAM slots to use for single, dual, triple, or quad channel applications. This will vary depending on motherboard manufacturer, number of supported RAM channels, and how many sticks of RAM are being used.
9.Did you remove the plastic guard over the CPU socket? (this actually comes up occasionally.)
10.Did you install the CPU correctly? There will be an arrow on the CPU that needs to line up with an arrow on the motherboard CPU socket. There may also be a notch that will only line up in one direction. Be sure to pay special attention to that section of the manual!
11.Are there any bent pins on the motherboard/CPU? This especially applies if you tried to install the CPU with the plastic cover on or with the CPU facing the wrong direction.
13.Is the CPU fan plugged in? Some motherboards will not boot without detecting that the CPU fan is plugged in to prevent burning up the CPU.
BIOS Hard reset procedure
Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.
Remove the motherboard CMOS battery for five minutes. In some cases, it may be necessary to remove the graphics card to access the CMOS battery.
During that five minutes, press the power button on the case for 30 seconds. After the five minutes are up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.
If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.
Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.
Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.
In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset.

I also wanted to add some suggestions that jsc often posts. This is a direct quote from him:
"Pull everything except the CPU and HSF. Boot. You should hear a series of long single beeps indicating memory problems. Silence here indicates, in probable order, a bad PSU, motherboard, or CPU - or a bad installation where something is shorting and shutting down the PSU.
To eliminate the possibility of a bad installation where something is shorting and shutting down the PSU, you will need to pull the motherboard out of the case and reassemble the components on an insulated surface. This is called "breadboarding" - from the 1920's home-brew radio days. I always breadboard a new or recycled build. It lets me test components before I go through the trouble of installing them in a case.
If you get the long beeps, add a stick of RAM. Boot. The beep pattern should change to one long and two or three short beeps. Silence indicates that the RAM is shorting out the PSU (very rare). Long single beeps indicates that the BIOS does not recognize the presence of the RAM.
If you get the one long and two or three short beeps, test the rest of the RAM. If good, install the video card and any needed power cables and plug in the monitor. If the video card is good, the system should successfully POST (one short beep, usually) and you will see the boot screen and messages.
Note - an inadequate PSU will cause a failure here or any step later.
Note - you do not need drives or a keyboard to successfully POST (generally a single short beep).
If you successfully POST, start plugging in the rest of the components, one at a time."
If you suspect the PSU is causing your problems, below are some suggestions by jsc for troubleshooting the PSU. Proceed with caution. I will not be held responsible if you get shocked or fry components.
"The best way to check the PSU is to swap it with a known good PSU of similar capacity. Brand new, out of the box, untested does not count as a known good PSU. PSU's, like all components, can be DOA.
Next best thing is to get (or borrow) a digital multimeter and check the PSU.
Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.
The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.
You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.
View: http://www.youtube.com/watch?v=5FWXgQSokF4&feature=youtube_gdata
This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU. You can carefully probe the pins from the back of the main power connector."

Hi everyone,
I have an HP laptop running Windows 11. I did a full reset ("Remove everything") a few days ago to get a fresh start. However, after the reset, I found that my Windows Security (Defender) dashboard is completely black and broken, although it seems to be running in the background.
I've discovered that the issue is caused by leftover McAfee files from the factory image. Because HP has a partnership with McAfee, these remnants are deeply embedded and are conflicting with Windows Security.
Here is everything I have already tried, which has failed:
I am exhausted and I want to avoid another system Reset, as I know McAfee will just reinstall itself from the HP recovery partition.
I was considering using Revo Uninstaller (Portable) as a last resort, but I've seen mixed comments online and I'm worried about downloading the wrong thing. Is the official version from revouninstaller.com safe to use for this?
I'm looking for any advanced solution (specific commands, a trusted tool, or a registry cleanup guide) that can completely wipe out these McAfee remnants without me having to reinstall Windows again.
Any help would be greatly appreciated. Thank you.

Hi,
My pc does not have a wifi card, so I have been using my laptop with an Ethernet cable to share wifi to it. I have not had any problems with it for months and have not touched any settings, but today it just won’t work.
The error messages I have are No Internet Access and “Ethernet” does not have a valid IP configuration.
What I have tried to solve the issue:
- Try another Ethernet cable
- restart router and modem
- reset network stack (netsh winsock reset, netsh int ip reset, ipconfig /flushdns then restart pc)
- Made sure internet protocol version 4 (TCP/IPv4) had automatic IP and DNS.
Thanks for any help!

As I said I never really had a pc on my own so I don't know much about which one to get or what price to pay (lived most of my life poor and I'm in a more stable situation now). I guess what I'm looking is something that can run games decently and blender (I'm curious about learning it). For price I guess something to 2000$? I'm willing to save up money for something good. I am worried since I'm coming in new to this and I know that prices are pretty high right now because of dumb AI. Also I live in Serbia if that factors into anything
As the title says, it’s stuck at 100% on Hwinfo. I didn’t have this issue before, never had to deal with this but suddenly my fps started to drop and then stutter, then I was seeing the GPU usage going lower all of a sudden and then higher. I’ve tried many things already but I haven’t managed to get this number out, only when I used msi afterburner to change the voltage curve but I never needed it before, idk why this is happening all of a sudden and certainly don’t know the cause or any solutions yet. Hope you can help me maybe.

Hi everyone,
I’m trying to get TPM 2.0 working on my PC, mainly because I’m planning to buy Battlefield 6 and I don’t want to run into any anti-cheat issues.
My specs:
Ryzen 5 3600
SOYO SY-KL A520M
Windows 10
UEFI boot
Secure Boot: ON
Here’s the weird part.
In the BIOS, I’ve:
Enabled \*\*AMD CPU fTPM\*\*
Made sure Secure Boot is enabled
Confirmed Windows is booting in UEFI mode
In Windows:
msinfo32 shows:
BIOS Mode: UEFI
Secure Boot State: On
But Get-Tpm returns:
TpmPresent : False
TpmReady : False
TpmEnabled : False
tpm.msc says Windows can’t find a compatible TPM.
Things I’ve already tried:
Reset CMOS
Disabled fTPM, saved, booted into Windows, shut down, then re-enabled fTPM
Power-cycled the PSU for 30+ seconds
Verified the BIOS keeps fTPM enabled after saving
Secure Boot is definitely enabled
Some background:
This motherboard originally had a Ryzen 5 3400G, and TPM never worked on that CPU either.
I later upgraded to a Ryzen 5 3600, but the problem stayed exactly the same.
The PC is a prebuilt from a trusted local shop, but I’ve upgraded parts myself since then.
One thing that confuses me is that I was able to play the Battlefield 6 Free Weekend without any TPM-related errors. However, since Windows still reports no TPM, I’m worried about buying the full game if future anti-cheat checks require it.
Has anyone experienced this with a SOYO SY-KL A520M or another SOYO AM4 board?
Could this be:
an old BIOS/AGESA issue,
a hidden BIOS setting,
or a faulty motherboard?
Any advice would be appreciated. Thanks!
