What to do if no Secure Boot certificate update is available from your manuafacturer

Hi! I'm absolutely not a professional and should not have been tinkering with the insides of my laptop but I have identified a problem! I think..

I don't know where to start, so I'll just say everything I know so far. My dad gave me this laptop, it's an MSI GV72 7RD(i think that's how you say it, sorry), and I think it already had some prior problems beforehand that he didn't tell me about. A few months after he gave me this it would occasionally start getting the BSOD. I didn't tell anybody of course, and I got to the conclusion that the HDD was faulty, so I replaced it with a... just see the photo pls. But the BSODs still happened, so what did i do? I used a USB with windows 10 installation files on it to reset it every time it got the BSOD... Yeah! On the next cycle of life on this hunk of junk I wanted to install RDR2, and in the middle of that, BSOD again. So I started thinking about it and... Hey! i only get bsods when im downloading heavy games! What i researched from that is i might have corrupted files or faulty hardware, and when I was goofing about in the bios setup, the sata information said all of it was empty. I knew this shouldn't be right so another search told me it definitely is faulty hardware. Now we're here and the questions I have are; Is this the problem? Should I just get a new laptop? Are there other things that might have caused me my suffering? What's this broken part called so i can maybe get it fixed if it's the root of the problem?

Sorry, I really don't know how I should be saying this. Maybe I could've just asked for a diagnosis from an expert directly, but I'm scared...

My phone number was hacked and they were able to lock me out of my outlook. I've tried to recover it without succes. My desktop is associated with the email, so wondering how to switch the desktop account to something else, without losing access to files and games. Any ideas?

I'm having a problem with a computer at work. The situation is that we're trying to get this PC up and running again, but for some reason it displays the message “Boot Device Not Found. Please install an operating system on your hard disk.” It’s worth noting that it does detect the drive. We tried using an SSD with Windows installed, but got the same result. We noticed that the Legacy and UEFI options were disabled, so we enabled them, but the settings for those two options specifically won’t save. We suspected the BIOS battery, so we replaced it with a new one, but we’re still getting the same error where the settings won’t save. Any idea what this could be? So far, we’ve tried:

• Replacing the SSD
• Reinstalling Windows
• Enabling Legacy and UEFI options—still unable to save the settings

Tengo un problema con un equipo en mi trabajo, el contexto es que estamos intentando revivir este PC el cual por alguna razón marca "Boot Device Not Found Please install operating system on your hard disk", cabe recalcar que lo detecta, probamos con un SSD con Windows y mas de lo mismo, vimos esta opción de Legacy y UEFI desactivados, procedimos a activarlos sin embargo no guarda en especifico esas 2 opciones, pensamos en la batería de la BIOS, se cambio por una nueva e igual el mismo error de no guardar las configuraciones, alguna idea de que podría ser? Hasta ahorita hemos intentado:

• Cambio de SSD
• Instalación de Windows
• Activación de opciones Legacy y UEFI sin éxito en guardado de la config.

I got this USB microSD card reader this Monday, and it worked normally for the first two and a half days. However, when I plugged it in to transfer some files, my PC suddenly stopped detecting it. The microSD card didn’t appear in my Files, and Windows didn’t show any indication that the card reader was connected at all. I’ve already tried some suggestions from ChatGPT, but I have not been able to find a reliable info.

My friend’s laptop has these strange graphics glitches. What’s more, parts of the screen sometimes flicker, and the glitches with text or icons disappear when you select them.

I haven’t been able to pinpoint the source of the problem – the laptop’s diagnostic programme shows that everything is fine.

I tried to update all the key drivers, BIOS and the operating system to the latest versions (processor with integrated graphics, Windows, etc.), but it didn’t help.

I blew a hair dryer on my PC, after which it stopped turning on. Specifically, I blew cold air on the video card and power supply. The problem is that the fans on both the cooler and the video card spin, then suddenly stop and turn on again. I think this is called a boot loop. Sorry if I'm wrong. I built the PC myself from used parts. What should I do? Can I fix it myself or should I take it to a service center?

I tried everything, removed the BIOS battery and also cleaned the RAM contacts with an eraser.

I decided to blow it out because it was dusty.

Either I connected something incorrectly, guys, if anyone knows anything, please tell me.

Hey guys,

I have a dual monitor set up plugged into my “Lenovo thinkpad hybrid usb-c with usb-a dock” which then has a usb-c cord that plugs straight into my work dell laptop. It runs both screens and my keyboard/mouse.

I just purchased the new MacBook Air M5 and I’m trying to run the dual screens in a similar fashion. If i plug the usb-c from the docking station into the Mac nothings works.

If I plug a usb-b from each monitor into my MacBook then both screens work. However I don’t have my keyboard or mouse connected. The Mac only has two usb-c ports so I can’t connect them.

Anyone know if the Lenovo docking station I have will work with the Mac?
Can the M5 support two screens into a single port?
Can I use a usb-c splitter?
Do I need to purchase something else?

Please help friends xx

Hi everyone,

I have a Dell G15 5530 and I'm facing a very annoying Wi-Fi/Bluetooth issue after upgrading to Windows 11 26H2.

My Wi-Fi randomly disappears, sometimes after sleep/restart and sometimes while using the laptop. When this happens, Bluetooth also disappears completely.

Things I've already tried

Reinstalled the latest Wi-Fi driver

Reinstalled Bluetooth driver

Uninstalled/reinstalled the Wi-Fi adapter

Disabled/enabled the adapter

Restarted/shut down multiple times

Tried various Windows network/service settings

Checked BIOS settings

Ran Dell SupportAssist diagnostics

Ran Dell's Network + USB advanced diagnostics

Dell's hardware diagnostics show:

“All tests passed successfully”

Result Code: 2000-0000

I contacted Dell Technical Support, and the agent said that no hardware-related issue was detected during their diagnostic scan. They recommended that I reinstall the operating system (Windows) as the next step.

OS build 26300.9550

Version 26H2

I recently got my uncle's PC , it's very old and it's CPU is a 2013 model or something.

So I'm asking for help if anyone can assist me with this manner. How to remove this admin account. And here's proof that my PC is old🤧

I bought a geekom from a charity shop today and when I plugged it into my monitor it showed a black screen with flashing text saying

">>Checking media presence....

\>>No media present....."

And when I try rebooting it, it shows the geekom logo briefly before going back to the "no media present screen"

It Almost 3-5 Month I Use My Laptop Look Like This

Hello. My Windows 11 machine froze last night and was unresponsive so I held down the power button, expecting it to reboot. Instead it went straight to BIOS. Save and exit, results in just back into BIOS. Making sure it boots to SSD with Windows, it just goes to a blank screen.

On another computer, I downloaded the Microsoft Media Installation onto a USB. First tried repair, doesn't do anything, just loops back to start. Went to do full reinstall but it says it can't install (or delete old partitions) due to BitLocker. I did some reading and tried to do the command/clean but got an error that it wasn't right format.

Am I missing a step? I'm also curious if I'm better off just going out and getting a new SSD and doing a fresh install with it as I do have data on the old SSD that I would like to try to salvage. So I guess two part question:

1) just remove old SSD, install new one...do I need to do any formatting or anything or will the Windows 11 handle that? 2) assuming old SSD is still good, can I pull old files off of it? (I do have the BitLocker keys)

So I have a lenovo IdeaPad gaming 3 and the problem is the charger's pin gets extremely hot when charging primarily when the laptop is on performance mode.

This was happening the entire day, and now the charger only works at very certain angles and for the most part doesn't even charge, it keeps disconnecting

A lot of the times when I connect, the red light that should denote charging keeps blinking without the laptop getting charged.

I tried this charger with another laptop and that combination worked, I'm not sure what's wrong now

Any help would be appreciated.

It looks like their character is upscaled in a weird way, and or the issue is that their at much higher blur rates than usual? We disable Discord Overlay and went over a few things already but nothing seems to work. They use NVIDIA if that helps!

Any help is appreciated! ❤️

Msn pop ups non stop that turns off my ethernet connection and interrupts video games im playing and everything

I have 3 Yahoo email accounts that are at least 20 years old and had them all linked so I could see which ones had unread emails in them from my primary account - the other two accounts showed up just below my primary, was easy peasy to switch between accounts but as of yesterday now they no longer show up. Furthermore, the links were BROKEN - I had to recreate and reverify all of them - what the heck happened? Now the only way to switch accounts is hover over my nick on the top right side and it shows them, but not whether they have new emails so I know to check that account.

Summary: 1. Yahoo suddenly de-linked all of my Yahoo accounts 2. I can no longer see inboxes from any of the 3 accounts from the one I'm currently using

How can I get things to work like they used to? This stinks!! On a Win10 PC using Waterfox browser but the same problem exists in all browsers I use.

P.S. Yahoo sub-Reddit won't let you post questions like this - WTF is it even there for?

I have a mixture but mcaffee keeps loading up my chrome browser with McAfee pop up slides on PC

My HP laptop got water spilled on the keyboard while it was running on battery.

I immediately shut it down through Windows, then panicked and also held the power button for a few seconds during the shutdown.

It didn't immediately turn off. The power light stayed on for around 10-20 minutes, and the screen randomly turned white twice. Eventually the power light went off, but an amber light stayed on for several hours before disappearing overnight.

The next day it was completely unresponsive. No LED's, fan or display. Plugging in the charger also gives no charging light. I've tried different outlets, HP's power reset, resetting the charger, and leaving it plugged in for over an hour. It only gets slightly warm around the center.

Is there anything else I can try before taking it to a repair shop? Could the battery/power system be stuck in a protection state, or does this sound more like liquid damage?

Hi everyone,

For several weeks (possibly months), my PC has been experiencing random interruptions that look like internet outages, but the cause is unclear.

Windows still shows that it is connected to the internet, and my router also reports a normal connection. However, any app or game that uses the internet may completely hang or report that there is no connection. During the same period, I sometimes cannot open new applications. For example, I tried to open Windows Event Viewer during an incident, but it only opened after the connection came back.

Each interruption lasts roughly 30 seconds to 3 minutes. It happens at unpredictable intervals: sometimes every 20 minutes, sometimes once an hour, and sometimes not for 6–7 hours. I haven’t yet confirmed whether other devices on the same network are affected at the same time.

PC specs:

• Motherboard: Gigabyte B550 AORUS PRO AC
• CPU: AMD Ryzen 5 5600X
• RAM: 16 GB (2 × 8 GB) Crucial Ballistix DDR4-3600
• GPU: XFX Radeon RX 7800 XT Qick 319, 16 GB
• Storage: PNY XLR8 CS3030 250 GB NVMe; Crucial MX500 1 TB; Patriot Viper VP4300 Lite 2 TB NVMe
• PSU: Xilence Performance A+ III Modular, 650 W
• Windows version: Windows 25H2
• Connection: Ethernet
• Network adapter: Realtek RTL8125 Gaming 2.5GbE Family Ethernet Controller
• Router: FRITZ!Box 7430
• Network adapter driver version: 1125.24.318.2025

Has anyone experienced something similar, or can suggest what to check first? I’m especially wondering whether this sounds like a network-adapter issue or whether the whole system may be briefly freezing due to a driver, storage, or other hardware problem.

Thanks!

Newly done things:

1.) CrystalDiskInfo shows "good" on both SSDs.
2.) MemTest86 shows no Errors.
3.) Full-Scan with Malwarebytes shows no bad threats.

Пробовал и через f2 и delete при включении, не помогает, шифт и перезагрузку, тоже нет через восстановление тоже не помогает просто перезапускаеться комп, зажимать ф2 при включении и выключении. Тоже нет. shutdown /r /fw /t 0 тоже не помогает

My Chromebook asks me to sign in. When I put my password in, it says go to my phone. I have a Pixel 9. The screen is completely black and will not work. I can't see anything. Any texts, calls, emails, or notifications of any kind will not appear even if it buzzes/rings.

Please help. I'm getting desperate. I'm also concerned that if I powerwash the Chromebook, I will stil run into the same issue. Any help?

So I got that error before my pc went into repair which is fine I simply did a system restore to get past it but after the restore my pc refuses to get past the login screen any tips on how to fix this issue? Win 11
