Onboard video chip cooked

[ACRIzona]

IBM S50 MS-7024 (MSI) mobo.
No video signals. No audible beeps. All voltages OK. CPU warms up to running temperature. Intel 77X video chip gets very hot.
Keyboard is dead. No disk activity. Ready for the scrap heap ?

Question: There are no switches on this board, so the bios must auto-select the built-in video or a PCI card.
Next to the video chip are two large wire things that look like jumpers... not the normal little plastic jumpers... these look like the big end of a paper-clip !

What are they ?

I think I'll snip one in half and see what happens.

The paperclip looking things are the loop mounts for the heatsink, do not snip them in half. Since when does snipping a soldered on component help anything?????? Doesn't the heatsink have a wire clip over it that is hooked down through those loops? If not, and that was how it was supposed to mount (they might have push-pins too and used those instead?), how is the heatsink staying on at all? Poor heatsink mounting could cause the video to fail.

However (and I admit I didn't web search your board to be certain, just generalizing...) the integrated video is typically in the northbridge so if the chip failed your more serious problem is not getting a different video card to work, it's that the northbridge functionality is essential to get it the system to run at all even with a different video adapter in the system.

However, it's possible that's just a poor cooling design and the chip sink just gets hot without there being a problem with it, that you instead have a more generic failure-to-POST problem due to some kind of fault or instability.
Had the system ran as-is previously, what has changed since it last worked? Have you tried clearing CMOS, measuring battery voltage and/or new battery, measuring PSU output and/or new PSU?

When a PCI video card is installed, typically what is required is to go into the bios menu and select it as the primary display device, but as mentioned above not being able to do that since you have no video, probably isn't the problem you are facing.

You right. The heatsink gasket was melted, gluing the heatsink onto the chip. There was no wire clip. I found a pic of the MB and see the clip which you describe. I think it will go back on the spare/junk parts shelf.
Appreciate you help.

It's like those computers on craigslist, that you can tell have onboard video, and the people selling them are like "It just needs a video card".

Well, if the system chipset is hosed, it's going to need more than just a video card.
