VGA stopped working

I had taken apart my Pentium-S computer a couple of times to solve an unrelated sound card issue (changing the jumpers on my SB16) and after the second time I put it back together and tried to restart the PC the VGA had stopped working altogether and I'm getting a weird beep. It's like, 1 long, 2 short and then a medium length beep, or possibly 1 long and 3 short since I'm reading that could be a video card issue.

I am assuming this is my video chip https://media.discordapp.net/attachments/6122 … =893&height=670

I tried taking it out and putting it back in same problem. Prior to this the VGA would flicker sometimes while connecting to my upscaler so maybe it was already on its way out and agitating the cards around it escalated the issue? But the sound card is 2 slots over so I don't see why it would have problems with that...

I feel very defeated because my midi cable WAS WORKING after the very first time changing the jumpers (It's just that changing the IRQ to 7 did not work so I had to change them back and as soon as I did that the VGA doesn't work at all....)

My gf who was helping me because I'm bad with small parts says when she took the sound card out the second time it was "louder" than normal but doesn't have any idea what it could have been, probably it just coming out not as smoothly and nothing looks abnormal to me...

AMI and Award bios 1 long and 2 short is video error. Try booting without the video card and see if it sounds the same.
If it does then try any other video card (even an ISA one) to help diagnose the problem....

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

I would need to buy one. Are there certain models that I am supposed to use with older computers?

If you haven't already, try cleaning the video card's contacts with some isopropyl alcohol and a lint free towel or cloth.

After watching many YouTube videos about older computer hardware, YouTube began recommending videos about trains - are they trying to tell me something?

I'll try, we have some laying around somewhere. But it's odd that it just stopped working right this second, when we were just messing around inside. It's not had those issues since I started using it again (except for some flickering with the retrotink occasionally). Though it is a PC that was sitting in the closet for many years. I have an XP computer but I don't think it's a graphics card that can be used with this one...I'd have to open it and see. I could search for an ISA card or another PCI card I just don't know if there's something specific I need.

If you have an XP computer then you can almost certainly test this video card in that computer.

The vga on the xp computer seems to be part of the motherboard, but when I extend the monitor to a second display, using my PCI card, it does show graphics but it appears low resolution and very glitchy (probably because it’s an older graphics card?) but I don’t know what else the problem could be if it’s not the graphics card itself. I do have ISA slots open, if the PCI slots are the problem..

This computer may have some other issues relating to the motherboard? The floppy drive wasn’t working so I got a new floppy drive and a new floppy cable and it still didn’t work. I also couldn’t get a pci usb drive working previously.

Edit: I realized that I wasn’t putting the card back in securely. After putting it in more securely, the beeping had stopped. However, VGA still was not displaying. However moving it to another PCI port did work. So I guess solved for now. Until the motherboard decides to break in a different way.

I've had computers where there were seemingly inexplicable hardware issues/failures that turned out to be caused by a failing power supply. If you have a basic electrical meter and are comfortable using it, this would be a good time to do some measuring. While this video is pretty basic, it demonstrates how to measure the voltage from a Molex connector (to my surprise, this was the best video I could find for this). If the voltage is too low, you would expect exactly this sort of behavior. Here in the US it isn't uncommon to have electrical outlets that aren't properly grounded and/or have the polarity reversed in many older homes and that also can cause very flaky behavior.
