I can't see any visible signs of deterioration, but the thing sometimes fails to recognize the HDD on boot. Always fails on a reset. Have to power down and back up. I guess it could be the drive. Checked the cables and they're all good. My kid found that if you give the box a slight whack when starting up, it detects the drive every time, so could just be the drive failing. Symptoms are very indicative of cap failure, though.

sounds like the drive needs a bit of help to spin up.
i would back it up asap before it dies.
you could have bad caps too but i bet the drive is shot.
it will soon get to the point whacking the case wont wake it up. -
Update: I have actually found that it will boot up just fine from a cold boot. If I have to hit reset, it fails to recognise the drive, but if I power all the way down, it boots as normal. Probably the caps, don't you think?Athlon XP 2400+

It sure sounds like it to me. Strange behavior from HDD controllers is typical with bad caps. They usually start out corrupting data once in a while, and as the caps worsen, they become flaky or completely unusable. Just to eliminate one more factor, try a different power supply. We all know Abit and their crap cap problem, so that would be one of my first suspects though.

That could be bad RAM. I had a similar problem with my PC after I'd replaced the caps. One the three DIMMs wasn't reporting, and once I removed the offending DIMM, everything worked fine.Originally posted by BOCTOKComment

I bought a KR7A-133R, that had already been sent back to Abit for recapping, unfortunately, it got damaged in shipping to the guy who RMA'd it, so he sold it to me really cheap. It had a couple of caps ripped off partially, although Abit did replace the caps with Rubycons. I replaced the caps that needed it, and the board works, with the exception of the AGP slot.
It senses if you have a AGP 4X card installed, as the Vagp will drop to 1.5V if one's installed. No visible POST if the AGP card is the only one in the system though. Funny the system still boots OK though.

Hi all
Hope this is in the correct place.
I'm planning on recapping both motherboards. I actually already ordered recplament caps for them, where I will be changing out most for poly's.
Could use some double checking to see if I'm not doing something stupid
.
Pictures of the boards are attached.
What I will be replacing with what : (planned)

Greetings,
I have an Abit BE6-II motherboard that posts sporadically with the bare minimum components installed - CPU, RAM, PSU, and a Keyboard. I know it posts when the speaker beeps. Re-seating the components has no effect.
I thought the sporadic posting might be capacitor related. Upon inspection, non of the caps are bulged or leaking and they are all original. So, I pulled them ALL. While the ESR is OK, over half of them are leaking current between 1 and 2 mA. The biggest offenders are way out of spec, like a 1500uf / 6.3V measuring 2600uF and many of the 820uF caps... -
I have a UE40F7000 Samsung which occasionally fails to properly come out of standby. The relay clicks and the backlight flashes but then goes off again with a click, and repeats. I think its temperature related as leaving it overnight seems to allow it to switch on OK.
I assume its PSU related and had a look - it's a BN44-00632B. No signs of swollen caps or hot components.
I saw a great YouTube video on a possible PFC related issues and an underrated resistor https://youtu.be/DREofE4WIvg?feature=shared though a quick trace from the SPC7011F pin 7 lead me to a resistor... -

A motherboard based on the Intel P35 Bearlake-P+ RAID chipset....10-31-2024, 02:06 PM -
Hello All,
I am trying to repair an old Abit ST6-R motherboard.
The symptoms are the following:
I got it in a non-working state. I was told that it sometimes turned on, but many times just the CPU fan was spinning and no other signs of life, the board didn't POST, and now it doesn't POST at all.
It was full of bulged electrolytic capacitors, so I replaced all of them with new Low-ESR ones, but it didn't solve the problem.
If I install a CPU in the S370 socket, only the fans are spinning and no POST. There are no beep codes even if the RAM DIMMs...
