Have you checked the voltage of the PS/2 header pins with a meter? This isn't for your board (though yours might be the same as one of these) but you get the idea.

Questions: what operating system are you using? What is the history on this board - is it recently acquired with no background of how well it works, or is it one you've had for a long time and the ports have only recently begun acting up?

I have replacements for the nine remaining Teapo caps on the way, but I don't feel at all confident that replacing them is going to solve this issue.

I tried downclocking the memory from 133 MHz to 100 and et voila 768 megabytes with no Memtest errors! But I still want to run it at 133 (this is all PC133)...

Why I suspect it is a power issue: while it works fine with 512 megabytes, that's only if a single 512 is installed - if I install a pair of 256 DIMMs (both of which passed alone) it will fail at the end of test five. I'm assuming that a pair of DIMMs draws more power than a single of the same …

FYI, TheRetroWeb still has no photo of this board. https://theretroweb.com/motherboards/s/soyo-sy-7vma-b Oh BTW, you might want to indicate which caps you already replaced. Looking at that photo there still seem to be some that should be replaced and likely those parallel to it as well. Okay, I'll …

Hoping for some helpful idea(s) on this problem. I have a Soyo 7VMA-B that was destined for scrap with bad capacitors. I replaced all of the capacitors that were visibly failing and, happily, the board seemed to work just fine. But as time has gone on, I've discovered a strange problem: with more …

I think that the FX 5500 is exclusively 128-bit. I'm just spitballing, but I can't think of any examples that I have encountered otherwise. Unfortunately this isn't true. I had a hard time finding a 128 bit one (a PCI one anyway), and one that I purchased that was advertised as such turned out to …

My PCI version FX 5500 turned up today. Popped off the heatsink, and...I've been HAD! It's a 5200 in disguse. It shows up as a 5500 though, some crafty VBIOS work from a factory in China. ...and here's the thing, it's not much better than the 16MB onboard on my Slot 1 board. Is it this bad because …

Synchronicity: on my local Craigslist there is a P2 system for sale in a desktop case that appears to have a nearly identical I/O plate to what you have. You can see how the two tabs are to fit in slots in the case.

Here is an example of the stock I/O plate that many cases came with. Since most motherboards the time fit this, it was left in place and the I/O plate that came with the motherboard was left in the box (and eventually thrown away). Then the computer was upgraded and the motherboard was pulled and …

That I/O shield is a proprietary one from some manufacturer. The hole pattern is typical for early ATX, it was the standard for about five minutes. The back of that case has screw holes for an I/O plate; cases from that era typically came with an I/O plate with that pattern held in place with screws …
