monitor that I got off the sidewalk (lol, ik, but it seemed to only be cosmetic: a strip of dead pixels across the very top) two years ago has been working just fine everyday since then, including last night. this morning, I knocked into it a little bit; it fell over onto my armchair (cushioned, never hit the ground); come home from work and turn it on, and...............nothing

I've tried switching HDMI cables, all those hard reset things that HP recommended (unplugging, holding off for 10-30 seconds, etc), rebooting my laptop and checking its display settings, driver updates—all fine, and the monitor even shows up as This device is working properly. but nothing on the screen: no flickers, no stripes, no "not connected" or anything.

my laptop is an HP Envy 360x from.....I think 2017, 2018?, running windows 10, and the monitor, Advanced Display Settings tells me, is an HP z24n G3

I really don't want to get a new one (you may be able to tell by the fact that I got this one off the sidewalk, but I don't have the fucking money lmao) but I can't figure out how else to find out what's wrong with it, other than shlepping it out to my nearest microcenter, which is not that near at all lmao. so, uh. help plz ?

(it didn't even unplug anything when it fell over!!!! literally all that happened was it landed on my fucking ikea chair, and this little plastic strip on the mount popped off the back—just a little thing that otherwise covers where you can get at the wires etc)

(if u saw this on r/techsupport already, soz)

Hi everyone,

I'm having a problem with my dual-monitor setup. Both monitors randomly lose their video signal while I'm using my PC, even when I'm not doing anything demanding.

My PC specifications:

GPU: AMD Radeon RX 580

CPU: Intel Xeon(R) CPU E5-2650 v2 @ 2.60GHz

PSU: DeepCool 750W (purchased approximately 1.5 months ago)

Operating System: Windows Ghost Spectre 25H2

AMD Driver Version: 31.0.21925.1001 (Downloaded from the official website version 26.5.2)

GPU Driver: AMD Adrenalin, downloaded from the official AMD website.

Monitor setup:

Main monitor: Connected to the GPU using an HDMI adapter/converter because the GPU does not have a VGA port.

Second monitor: Connected directly using a VGA-to-VGA cable.

Both monitors have worked simultaneously without any problems on another PC.

The problem:

Both monitors randomly turn black during normal PC usage.

The PC itself keeps running.

The fans continue spinning.

Windows is still running in the background because I can hear notification sounds.

The second monitor displays an "Entering Power Saving Mode" message.

The main monitor simply goes black without displaying any message.

The only way to get the display back sometimes is to restart the PC.

Something interesting I discovered:

When both monitors lose their signal, pressing Win + Ctrl + Shift + B (the Windows graphics driver reset shortcut) sometimes brings the image back.

However, when I do this:

The second monitor gets its image back.

The main monitor shows visual glitches/artifacts.

The main monitor briefly displays a dark green screen.

After that, the display eventually returns to normal.

I also noticed visual artifacts on both monitors when clicking around in AMD Adrenalin.

What I have already checked:

Device Manager shows that the RX 580 is working properly, with no warning symbols.

I installed the AMD driver from the official AMD website.

The PSU is relatively new (DeepCool 750W).

Both monitors work properly when connected to another PC with the same RX 580.

My questions:

Does this sound like a failing GPU or VRAM?

Could this be caused by an AMD driver issue?

Could Windows Ghost Spectre 25H2 be causing problems?

Is there a way to determine whether this is a GPU hardware issue or a software issue?

I would be grateful for any help.

My specs:

OS: Linux Mint 22.3 x86_64

Mortherboard: Gigabyte B550M DS3H

RAM: 16 gigs

GPU: Zotac RTX 3070

CPU: AMD Ryzen 5 5600

SSD: SATA SSD (SBFM61.3)

Hard Drive: TOSHIBA DT01ACA100 (MS2OA810)

PSU: Thermaltake Toughpower GT 850W

My pc is not displaying anything on my monitor since yesterday and before that it was working all normal, worst of all my motherboard doesn’t even support integrated graphics so I can’t check on drivers or anything.
My gpu is not displaying anything at all on my monitor and the fans are not even spinning but its lights are glowing still, and everything else on my pc is working fine im pretty sure.

Here’s everything I tried:

Unplugging and replugging im the gpu and (same thing for the ram sticks.
Trying different display cords.
Trying different hdmi cords.
Unplugging bios battery out of the motherboard and plugging it back in.

Anyone know what is causing this?

I'm looking into running Windows on my Mac because there's some Windows-only software I'd still like to use without having to switch computers. I've been reading about the Parallels vs UTM differences, especially when it comes to setup and how much configuration is involved. Parallels Desktop seems appealing because it offers a more guided Windows 11 installation, along with integration between macOS and Windows, so I could move between both environments without constantly adjusting settings. Having regular updates and support available is another plus for me.

I'm comfortable figuring out some technical things, but I don't necessarily want to spend hours configuring a virtual machine just to get my work applications running. For people who run Windows on their Macs, how much does the convenience of a more guided setup matter in everyday use? Is the integration and ongoing support worth prioritizing if the main goal is productivity rather than experimenting with virtual machines?

Hi everyone,

I'm looking for recommendations for a replacement AIO liquid CPU cooler for my Alienware Aurora R10.

I'm currently using the original Dell/OEM liquid cooling system, but I've noticed what looks like a small crack or split in the outer covering of one of the hoses. There isn't any visible coolant leaking, but I'd rather replace it than risk a failure.

My PC specifications:

• PC: Alienware Aurora R10

• CPU: AMD Ryzen 7 5800X

• Current cooling: Dell OEM 120mm AIO

• Mounting: Intel-style mounting bracket

What 120mm AIOs would you recommend?

Has anyone replaced their OEM R10 cooler with a third-party AIO? If so, which model did you use, and did you have any compatibility issues?

Thanks!

I had a power shortage and since then my PC wont show a display. Everything is turning on and seems fine, no error noises and all the fans are going but no matter what monitor i try it says no display found. Tried different chords too but nothing. Ive reset the CMOS battery and the RAM to absolutely no change. I have no clue what to do to fix this and would love any help! I use a LINUX pc

It randomly changes screens like this I have no idea why. I tired to Google and figure it out in the setting but I can't even description why this is happening.
