Re: New Caps on ASROCK K8 Upgrade 760GX quit working
As I stated in my post, I did install new caps to replace the ones installed backwards and that fixed the problem. The motherboard posted. The problem now is that I changed a different group of caps, installed them correctly, and the motherboard would no longer post. I put the old caps back in and it still will not post. Thanks...

Re: New Caps on ASROCK K8 Upgrade 760GX quit working
I assumed the two questions were asking a different questions. My answers as I understood the questions are not contradictory. I just misunderstood the question(s).
Answer to Question 1: All the voltages on my PSU tester showed correct values.
Answer to Question 2: When I attempt to turn on the computer the PSU does nothing, (it is not running) and neither does the motherboard.
It does sound like a short in the motherboard though. There are no solder bridges, splash, or any signs of any issues on...Leave a comment:

Re: New Caps on ASROCK K8 Upgrade 760GX quit working
Yes, they are good.
No
I have not tried. My Fluke died and is sent in for repair. My current meter only has big awkward alligator clips.
None are reading shorted. Some start out at 30+ ohms and quickly shoot to infinity. Some start out around 2 to 10 ohms and take several Minutes to reach infinity.
I did not find any -obviously- blown FETs
I did replace all the caps with new ones (correct orientation this time) and...Last edited by ladalet; 07-15-2011, 05:55 PM.Leave a comment:

Re: New Caps on ASROCK K8 Upgrade 760GX quit working
Well, apparently that is a much larger population than I would like to admit
Unfortunately rotating them changed nothing. I hope replacing them will all new caps will do the trick and I have not toasted the motherboard. I wonder how many times the PCB can tolerated changing caps before damage? I really do not look forward to telling my sister that I broke her computer
CRAPPY!!! but perhaps better than caps--lately at least

Re: New Caps on ASROCK K8 Upgrade 760GX quit working
SOB!!!!
Pardon my acronym. I think you nailed it right on the head. I was so used to the white side being ground that I did not notice that is is reversed on this board. What a lame mistake. Well, that is why forums like this sometimes exist is to straighten out stupid mistakes. Wow, thank you very much. Should I just junk these caps or do you think that rotating them to the correct alignment is adequate? Thanks again.
P.S. I will post the outcome of getting the cap orientation right when...Leave a comment:

Re: New Caps on ASROCK K8 Upgrade 760GX quit working
Yes I did. Thanks
Rubycon sorry for the typo. Given the nature of all the counterfeit caps currently on the market, the spelling could be very meaningful.
Thanks, I was just trying to find and difference that might signal at least signal a hard fail of a cap and thus explain the failure. What you say make sense. Yes, after discharging them and then retesting them with my ohm meter, they do show resistance and the quickly rise to infinity--open circuit)....Leave a comment:

Re: New Caps on ASROCK K8 Upgrade 760GX quit working
I guess I could be a bit more explicit. Does it sound like one or more of my new replacement caps are defective? The motherboard actually worked until I installed the new caps. Plus, 2 out of the 5 don't even register at all on an ohm meter whereas the other 3 uniformly do. ThanksLeave a comment:

Re: New Caps on ASROCK K8 Upgrade 760GX quit working
This is just an additional note to my previous post. I know this is not a kosher capacitor test, but I do not have a capacitance tester. However, I do think this may be meaningful. When I put my ohm meter on three of the 5 caps the resistance rises to about 58 ohms and stays solid. On 2 of the 5 caps I get infinite resistance or no continuity.Leave a comment:

New Caps on ASROCK K8 Upgrade 760GX quit working
Hello, my sister was having some stability issues on her computer. I noticed that 5 of her 3300mf 6.3v caps were bulging. I replaced them with Rubicon caps and the mother board now shows no signs of life. All the filets look good. I am using Kester 63/37 .031 ra flux core solder. I pre-tinned and fluxed the pins prior to soldering and keep the act of soldering to about 3 seconds. I do my best to follow IPC protocols. I am using a Metcal PS2E-01 station and a 700F 1.78mm chisel tip for the ground plain side and a 600F 1.78mm chisel tip for the positive side. I pre-fluxed the filets and used my... -
Re: Gateway FPD1975W only works in safe mode
No, I only replaced the caps on the power supply.
Some new information: The monitor works not only when in safe mode but also in VGA mode, normal mode with generic VGA adapter drivers installed, and works perfectly plugged in with a VGA cable and DVI adapter. With the VGA cable and DVI adapter the monitor even defaults to a generic monitor driver but the correct resolution (1440X900), refresh (60hz), and color (32 bit). I also installed the correct DVI inf file and loaded the correct drivers for the monitor....Last edited by ladalet; 01-05-2011, 10:12 AM.Leave a comment:

Gateway FPD1975W only works in safe mode
I recently replace the caps on this Gateway FPD1975W. It was not powering on at all. After replacing the caps it would power on and lose the signal as windows began to load. It would go into safe mode and work fine. If I uninstalled the ATI video driver and used a generic video driver it would work fine. I uninstalled and reinstalled the ATI driver and it worked until I attempted to raise the resolution over the 800X600 or attempted to change the color from 16 bit to 32 bit. The installation defaulted as a plug and play monitor at 800X600 16 bit color. I had to uninstall and reinstall the video...
