Roland Of Gilead RubenM said: "Person replaces blown cap" That could have been your article. Well, yeah. It could have been called that. But,IMO they chose a good one, You may not like it, which is your perrogoative, but it's meant to be something lighthearted, in a time when PC component pricing is insane, and having a cheap and cheerful fix that would save the OP $120 is cool. What's not to like!? I had a smile on my face reading it. Good upbeat article. Also, Kudos to the Old Schoolers! Reply

Lieutenant Barclay I knew Kuwait called their currency the dinar but TIL Serbia does too. Although Serbia's dinar barely constitutes a light supper :LOL: Kuwaiti dinar: $3.23 USD Serbian dinar: 1/10th of a penny Reply

TheEmrys Pretty sure it should be Jury rigged, as it wasn't done poorly. Jury rig needs a defender. Jury rig vs Jerry built Reply

Gururu This also makes me smile and appreciate the will needed to move forward. Almost anyone would have abandoned the card. Having spent more time on fixes that were probably better spent replacing, this story gives me a glimpse in what humanity may have to overcome as people are left to maintain decade old hardware. All the more convincing as companies are competing for dollars against used components by reintroducing old product into the marketplace. Reply

xxyyzz666 "but the capacitor itself isn't suited for long-term usage because of its higher resistance, which would let the clocks run unchecked" What is this BS? Just say nothing if you know nothing. Based on the size of the capacitor it likely provides a bypass and local storage/smoothing capacity, and seems extremely unlikely to have any influence on any clocks. Capacitors of this type are frequently plus or minus 10 or 20% of the stated value, so if it was used in clock generation circuits it would be a crap clock, plus at that value it would definately be a sub 1MHz clock, which doesnt sound that useful for video, or anything really. The performance parameter of interest is likely to be ESR and the construction type, while influencing ESR, is most likely to do with physical size and longevity. TBH, I am surprised that the loss of that single component rendered the GPU totally inoperable, that is a worryingly fragile design. Reply

Yes, this, it's a filter/smoothing reservoir cap, and that generally needs a high quality, low ESR cap for reliability or it will run hot and fail again soon. As others mentioned here, the younger generations have lost the skills of being able to repair equipment, even basic repairs are beyond most of them. But, it's also pretty clear that the author knows buggerall about capacitors and electronic circuits either, not uncommon nowadays even on tech sites. The level of real tech knowledge (as opposed to knowing how to use devices and apps) has plummeted dramatically in the last 20 years across the entire population. Reply

Key considerations

  • Investor positioning can change fast
  • Volatility remains possible near catalysts
  • Macro rates and liquidity can dominate flows
