Let me add one common issues that plagues some of my PCs, it's those horizontal speckles, i think it's electrical noise bleeding from other cables or devices connected nearby but if anybody knows this specific issue i would appreciate it.

What interface, monitor and system (specs) are you using for this?

Since the problem is inside the chip, there's nothing you can do really. It's faulty and needs to be replaced.

VGA, LCD (but that's from a capture card) the specs: CPU: Intel® Pentium® 4 CPU 2.65GHz - L2:512K - Northwood
Motherboard: American Megatrends Inc. - M935D Rev 2.0
RAM: 512 DDR-SDRAM - PC-2100U single channel 133Mhz
GPU: GeForce 4 TI 4200
Soundcard: Sound Blaster Audigy Platinum EX

It's a noise present even on some consoles, hence the electrical issue.

Let me add that this issue is present only in the capture but not on the LCD, I tried connecting everything directly bypassing any switch or splitter and the noise is still there, I'm also using shielded cables and really thick ones.

Can't hurt to wash the card.
Normal boring soapy water with a tooth brush and a long sun dry.

You'd be surprised. I've fixed completely dead modern GPUs with a simple wash.
My theory is that conductive dust caused issues.
I don't know for sure, but I know the results have NEVER made it worse.

Yeah I've actually had a problem before with some fine organic dust, seemed like superfine wood or maybe paper/cardboard dust, like what maybe happens in an office. Anyway, that seemed to be hygroscopic, drawing moisture from the atmosphere and it was making a slightly conductive bridge between pins on an i/o chip causing malfunctions. I guess it packed in there dry, randomly from airflow eddies, but when it got the slightest amount of moisture in it, it jammed in real hard, and while loose damp dust wouldn't have a very low resistance, the combo of the pressure from it swelling and the gaps between pins being very small brought it down around a kiloohm or so, which was disruptive.

I tried with alcohol, no dice. But at least it was squeaky clean 😁

I find water, the universal solvent, is better.

Alcohol for the rinse before drying.
