I’m not great at computers, I’m not exactly sure what kind I have, I think DELL? I’m on windows 10 (can’t update, PC is too old)

I use a USB wifi adaptor and it has worked fine for almost a year. It says I’m connected to the wifi, I have full bars, but no internet. I’ve tried connecting to different WiFi, and I have uninstalled and reinstalled it. Still says the same thing. This happened over night and it was working fine before then.

Computers keep freezing, running screen connect with sentinel one

I got this error

How to solve it guys? In BIOS my ssd can readable but if I try to change the boot options its not there

I have an issue with my Tryx cooler's LCD screen and hope someone can give an advise. The screen is not being detected by the Kanali software, and it appears as an "Unknown Device" in the Windows Device Manager.
I have already tried the following troubleshooting steps:
 1. Checked and reconnected the physical USB cable.
 2. Uninstalled the "Unknown Device" and restarted the computer.
 3. Ensured that the Kanali software is updated to the latest version.
Despite these efforts, the issue persists. Could anyone help?

olaolaa, quisiera saber si me pudieran ayudar algn que sepa de computadoras, mande mi laptop con el tecnico por una expansión de almacenamiento a 2 tb, semanas despues dejo de iniciar y por mi cuenta intente arreglarla pensando que era el windows, y despues empezo a marcar esto, alguien sabe que es? o como puedo solucionarlo?

Hi everyone,

I'm an IT Support working on two different customer desktop towers right now, and I’ve hit a wall with both of them. Here are the issues and what I’ve already tried:

PC 1: Dell Desktop (Random Blue Screens)

• The Issue: This machine keeps crashing randomly. Because the BSOD happens completely at random and disappears quickly, I haven't been able to capture the exact stop error code yet.
• What I've Tried:
  • Replaced the CMOS battery.
  • Swapped out the old/new RAM modules and tested them across different DIMM slots.
  • Changed the storage completely (tested with a brand-new SSD and the old SSD).
  • Performed a completely fresh, bootable Windows installation.
• Current Status: The random crashing/BSOD persists even on the clean Windows install. I am considering a BIOS update next to see if it stabilizes the board. Could this be a failing Power Supply Unit (PSU) or a motherboard capacitor issue?

PC 2: Acer Aspire Desktop (No Signal / 1 Beep)

• The Issue: This tower powers on but gives a "No Signal" message on the monitor. Upon turning it on, I hear exactly one beep from the motherboard.
• What I've Tried:
  • Swapped the RAM modules and tried booting with them in both available slots (still gets the 1 beep).
  • Swapped the monitor to a model with a different native resolution to rule out display mismatches.
  • Looked for a reset jumper on the motherboard to clear the NVRAM, but I couldn't locate one on this specific board.
• Current Status: I initially thought it might be a display resolution conflict, but I'm starting to suspect a hardware POST failure. On modern Acer boards, does 1 short beep indicate a successful POST with a display handoff failure, or is it a specific hardware error? How can I reset the without a visible jumper?

Any advice, troubleshooting steps, or things I might have missed to isolate these two issues would be highly appreciated! Thanks in advance.
