How old is the PC?
I've seen more in monitors and PSU's than on mobo's, but I've had 2 personally, and my parents had one. These were all cheaper boards (ECS or MSI), not my usual Asus ones, and the last one was either a socket 478 board with a bunch of years on it.

Back in '02 or '03 so we had a rash of PSUs, and then mobo's' that suddenly started having bad caps. IIRC it was a very large batch of counterfeit caps. I know that the PSUs were all in small form factor K6 boxes that got very hot, and I think the mobo's were Asus Tualatin based socket 370s, again in very tight boxes with low airflow.

With the PSUs they started with a recall, but ended up sending us caps so that we could turn them around faster (we probably had 300+ boxes in the field, and this vendor served a lot of other industries as well).

With the mobo's they were all out of warranty by the time it started happening, so the owner had us trying to replace caps on them to save money.

Either replace computer or replace mobo but do not pay a computer store to replace the caps.

I still haven't been given a good reason why not try the least expensive way first?

Under $100.00 compared to $500.00 or More?

If it blows (cap) again .. I would go new pc but why not the lesser route first.

(If you insist .. I can take up a collection)

Just kidding everyone but Thanks!

In my mind, it's the low chance of success. It's not about blowing it again, but about a recap not actually fixing the problem.

It's like any other gamble; there is a decent chance that you'll lose, so don't invest more than you can afford to lose. If you are willing to gamble $40 or $50 on the chance that it will work (with no guarantee), then there's nothing wrong with it.

I've seen a number of them, older Intel boards and not so old Asus boards, along with various OEMS such as HP. Also a number of power supplies and LCD monitors, even a Linksys 24 port switch.

I didn't say I didn't believe, daveB... just that it's new to me. Or it may not be... if I did have a dead mobo I would just replace it and not bother troubleshooting down to a component level...

I think that I've just grown used to checking the caps first, since it's easy to spot, and I tend to immediately diagnose the board as trash as soon as I see them (no reason to diagnose anything else at that point).

I haven't replaced caps on any mother board that I've owned (only for my previous employer), but I've recapped a number of monitors, and a couple of PSUs, and gotten several more years out of each one (for less than $5 each time).

I did have a UPS that I replaced a couple of bad caps in, and it still didn't work, but it was worth trying for a $100+ UPS.
