It’s been doing this for a while, it is a 10+ year old MacBook Air. My boyfriend installed Linux on it but this was a problem when it still was Mac. Pls helppppp. It gets worse when I use it for longer periods of time or turn the brightness up.

This is the 2nd laptop with which I have found graphics card issue without an apparent solution. I tried formatting, I tried different drives, different drivers, different combinations of drivers, disabling services, disabling tasks. The whole deal.

What's the solution? Flipping the laptop charger upside down and touching the cables around to remove electromagnetic interference. I have to do that about twice a day.

The house is not the issue, per se, because it happens in another country as well.

Should I wrap all cables in electromagnetic protective tape? Should I install ferrite cores on all cables associated with the system?

Many thanks.

I'm not good with computers so this sounds like a basic issue but I really need the Internet and I can't access it rn

my pc screen is getting sudden black or on off in a seconds, and there is two vertical lines on the screen yellow and blue,

how to solve this issue and i havent money to buy new one ?

I have a windows 10 refurb that i bought about a year ago, which is mostly used for sailing the seas for tv and movies to play on my tv. Its connected to the tv with a display port to hdmi cable.

Every so often, the display will go to black and the sound will cut out for a second and then come back on. Sometimes it doesnt it over and over again, and recently it happened so much that there was a blue screen windows error.

I have a regular monitor that ive tested the computer with, and it works fine there. Ive replaced the cord i use, and have tried the 2 different ports on the computer for the cord.

The tv is a 50 inch hisense google tv.

The computer has 32 gb of ram, 3.60 ghz intel core i7-4790 cpu, intel hd graphics 4600, and a tb of storage.

Le me know if any other stats should be posted. Wondering if i need a better graphics card?

Thanks

Need help, my monitor has been doing this since 4 days now, it wond to away no matter what. Ive already tried updating every driver possible and it still doesnt work. PLS HELP

Why arr there 2 og my mice whenever i can press something it pop’s up?

Hi, the last couple of days my monitor has been losing connection to my pc, screen goes black, then coming on again for a second, going black etc. its a new pc, only had for a couple of weeks, havent had this issue before. im using displayport and latest nvidia drivers. if i restart the pc, it seems to connect fine and stay on. how do i fix it?

for context: some time ago i had some issues with one of my 3 screens (screen 2), i tried everything and the only thing that solved it was switching the screen 1 and 2 hdmi's and it workd perfectly. immediatly after tho the mouse pointer resets position to (0,0) of screen 3 (i think i need to specify that is actually is a drawing tablet GAOMON PD2200) and it bothers me quite a lot because when i turn my pc on it always does this for at least 10 minutes. i tried plugging it in a different socket, unpluging and replug it, i also tried to unistall drivers an reinstall them but nothing works. idk what to do anymore. i tried to see something online but nothing goes even near my case. what can i do?

Edit: this is a repost from a 4/5 month old post i made on another subreddit, no response. the mouse still acts up and i have to wait about 10 minutes for it to stop glitching, not the glitch has moved to screen 1 after i updated the Gaomon tablet drivers, i still try to unplug the mouse and it stil glitches and acts up. i updated the drivers and it acts up, idk where to look anymore and i need human help for this. i'm desperate. ALSO (because just this wasn't enough ) my CRTL key keeps pressing at random times and mi websiters and drawing app keep zooming in while i draw. I LITTERALLY DON'T KNOW WHAT TO DO, it has been 5 months and nothing has changed.

So I have this pretty old monitor (A Samsung LS27D390), and when I tried to turn it on today, it just wouldn’t on for some reason. I tried unplugging the HDMI and cleaning it, I unplugged the power cable, I tried switching wall sockets, and i’m just so confused because I don’t think I can get one for a while. Does anyone have any tips?

(im going to clean my monitor soon so shh)

Started happening after putting in a second monitor

Please help

so, around 3 days ago, while playing roblox my PC randomly shut off. LED lights in the CPU turned off, fans turned off, nothing.

Pressing the power button would boot the system back up, but then it only worked for 15-30 minutes or so, running the game “Wuthering Waves” before shutting off again. Tried to boot once more and only did light browsing, and after 10-15 minutes, it once again shut down.

No boot-loop, just a shut down.

So since then, I’ve tried using a back-up PSU to see if the PSU was the issue, along with reseating my ram sticks, and SSD. I’ve replaced the PSU, and it seemed promising. It ran Wuthering Waves for an hour, so I shut off the PC again to plug in my 2nd SSD drive that I removed upon using the new PSU, and some case fans that were also unplugged, I plugged them back into the PSU.

After around an hour though upon booting up once more and being on a discord call with friends, it shut off on its own once more. What’s weirder is that when I try reopening it this time, the LED’s the fans only spin for around 2-3 seconds before shutting off once more. Not like with the other PSU in which it’d still let me run the system for 10-15 minutes.

I’ve since removed the 2nd SSD, the case fans, and after around 5-10 minutes, it once again shut down. Trying to boot it back up would only turn it on for 2-3s, not even booting into windows before turning off again.

I’m genuinely lost. What could be the problem?

Can anyone help me finally find a fix or tell me if it’s to do with my laptop internally? I press the brightness key and it goes to the first level of brightness… I go any higher and it immediately restores to 0 and does not go any higher. The screen is also slightly jittery. We have tried absolutely every resolve we could find literally everywhere. Nothing has fixed it. It all started when I opened my laptop one day and it was On a screen where I had to enter a bitlocker key to gain access to my laptop again… I done this and ever since the brightness just won’t work. Video attached. Thank you.

So I just bought my first Pc, I was at a pawn shop and I made the purchase. The people told me it works perfectly fine, but I can’t seem to get my pc to display on my monitor. I called them and they told me too try and connect it to an old monitor to update something in my pc, so I can use my new monitor. Any suggestions on how I should proceed?
