Re: I need Dell GX60, GX260, and GX280 advise...

Thanks everyone for the replies. I ended up buying a Build You Own ESR tester on eBay. I assembled it and began testing caps that were inline on the power supply. After doing the tests, I found one cap who's ESR value was way off (around 26.0 and it should have been around 1.0). I pulled that cap off the board and tested it again. It came down to 15.0 so testing in line can affect the value it seems. I put a new cap in that had the right value and bingo, problem solved FINALLY!

THANK YOU ALL SO MUCH!!!! This has bugged...

Re: I need Dell GX60, GX260, and GX280 advise...

Thanks for the replies. I have just been really stumped.

>>"Sometimes, higher ESR is associated with capacity loss."
Thanks, I'll look into that. I know the caps I purchased were supposed to be very low ESR but you never know plus other could be bad. I'll have to look up how to test ESR rating because I already had to convince mt boss to let me get a meter just to check the cap values. Maybe it will do ESR as well.

>>"likely problem is the 5vsb circuit"
I thought...

I work in the IT department at a call center and most of the operation computers are a GX series computer (Mainly GX280) and I have gotten quite proficient at replacing bad caps and restoring the PC to working condition. However there seem to be a select few I run into that still plague me.

The main problem I run into is after all caps that appeared to need replacing both on the mother board and the PS were replaced, I still get the orange blinking light of doom and cant figure out why. I am sure the problem is in the power supply because when I swap it out for a good one, it works...
