    I am in Emachines and Compaq hell. Help me get out

    Hello to all you wonderful techies. This is my first time ever posting on a forum, but this site has given me a glimmer of hope. Could I be suffering from the bad caps plague? I have much experience soldering so if it is the caps, I might elect to DIY; you make it sound so easy. Here is the sad story of "My 3 computers". I'll make it as brief as possible. All were purchased used.

    1)Compaq 5202, had several near death experiences, and currently will not POST at all. The HD is okay, but on power up there is no logo screen, Monitor goes to the amber led mode, HD starts to read then stops. It has a gerry rigged power supply, which worked wonderfully after the stock Compaq one died.
    It powers down after pressing and holding the power button for a few seconds, in the normal way. All voltage readings done with my VOM are normal. Could the problem be the caps?

    2) Emachines 466i was a wonderful replacement for the Compaq with MS Windows 2K Pro OS but had some weird problems right off the bat. Like random "small memory dumps", then after long periods of being not used at all (because I finally acquired computer #3 with XP) when I would fire it up to update the security software, etc. the HD would display about 2 lines of Martian (or maybe from Uranus) lettering, without loading OS. At this time it seemed to have okay POST and I thought the HD was near death but on reboot everything was fine. Then the biggest problem yet- a blue screen of death "STOP error" that wouldn't go away suggesting that I might have a virus and to use CHKDSK /F which was pretty hard to do since the freaking computer was dead. But alas, I used my wonderful later model Emachine C1641 with Windows XP, installing the 466i HD as a slave, to do the CHKDSK with Fix. This seemed to work, as I reinstalled it in it's Emachine 466i box; it booted and ran beautifully. It shut down normally and seemed like completely restored.
    I felt like a genius for less than 24 hours. Then when during the next boot right in the middle, of loading the OS, I did the biggest duffus thing in the world. I accidently shut of the power strip the system was tapped into. Hard power failure. After that, it tried to restart but is now doing exactly what the Compaq does, i.e. NO POST, NO LOGO SCREEN, (read above #1) Could it be the caps or have I killed my motherboard somehow by accidently shutting off the power?

    Then I found your site. You folks are my kind of peeps!.

    On to #3, the Emachine C1461, has been wonderful until today, I decided to put the HD from the 466i back in as a slave so I could at least retrieve any data from it that I needed. Then I saw that to my horror some of the caps are bulging, just like in your pics of bad caps. Then, as if on cue, when I went to fire it up, it was doing the same thing as the other 2, NO POST, NO Logo screen, etc,. After I went to the bathroom to throw up and after praying heavily, and after reseating every freaking cable, and card on the mobo(except) the CPU, I tried again, and now it was giving me lip, in the form of a series of long, loud, beeps, that were almost deafening. After trying one more time to reseat everything, she finally booted up, with one small problem, the date went backward to 1/1/2002. All seems okay now with the Emachine C1641 but I know it too is on borrowed time since the caps even look bad to me. I also noted that it has a Bestec PSU, which several of you guys have said are junk.

    Here, finally, are my big questions, knowing that several of the forum threads have declared Emachines to be worthless, do you think it is the caps on the Compaq 5202, and the Emachine 466i, or is there a CMOS , BIOS reset needed. If the vote is, "IT'S THE CAPS!" is it even worth it to replace them on an Emachine mobo or the CompaQ?


    Thanks for your time and help in these matters. I am willing to learn more always.

    Well if you see any bulging or leaking caps, you have a problem. These could be on the motherboard and/or in your power supplies. You need to closely examine them, and even if they aren't leaking but are on this list, chances are they are junk.

    You can always post pictures to the forum if you are unsure of what you are looking at. As for resetting the bios, since this only takes a few minutes and is the simpilest (if not the most common) fix for weird booting issues, why didn't you try it before posting your message? Anyways you probably want to do all these things...

      Didn't know about clearing bios/cmos fix, but oddly enough, found out before your post how to do it safely, and voila, this solved the Emachines 466i POST problem and it is now back on line. The hard power failure must have somehow glitched it. It did decide to do a "small memory dump" right off the bat tho' but has been solid after that for about 3 hours.

      However, this reset bios did nothing for the Compaq. It still will not POST at all, but HD spins and I can power it off normally.

      At least, I am half way back from the pits after learning how easy it is to reset the bios.

      The caps all looked fairly good to me on the 466i and Compaq mobos but didn't know to check the PSU. Will do that next and check your list link, and thanks for your help. I understand from several posts here, that caps can still be bad even when they look good and test good. Weird! They seem quite elusive.

        The Bestec in the Emachine is probably the reason for the bulging caps. Replace the power supply before it blows up the south bridge chip on the motherboard, then recap the board. Should work fine from then on if you get the caps done right. I have personally witnessed a couple dead Emachines because of the darn Bestec PSU's. Compaq used them in a few machines as well.

        Also run Memtest86 to test the RAM afterwards.

        I suggest practicing recap on a dead motherboard to make sure you have a good enough soldering iron and a feel for it before doing it to the working stuff.

        For the Compaq, unplug everything but the RAM and video, and try a different power supply.

          I'd also recommend running memtest86, especially if you are getting memory dumps.

            Here is an update of my progress so far, thanks to MixMasta and Maxxarcade.

            I decided to give the Compaq one more chance with a lengthy (like overnight, instead of the 10 minute standard) Bios reset by removing 3V battery, which measured 3.06V. next morning put brand spankin' new 2032 measuring 3.33 V. AND VOILA, the Compaq has been resurrected from the dead. I'm used to replacing this battery but on this oldy but goody computer, apparently, it wanted a little longer rest to clear the BIOS and a new 3V. Interesting, eh?

            All caps seem good on the 2 older ones (466i and Compaq 5202), but I still am going to check PSU caps.

            Never heard of Memtest86, but googled to find it and will do this next.

            As far as the bulging caps on my best XP computer, now I am definitely going to practice on some scrap boards I have, with replacing the caps. Between the Bestec and the bulging caps. This seems to be quite urgent to take care of ASAP. I live online, and would hate it if I lost my XP OS. (Windows 98 Compaq and W2k Pro 466i are for emergency backup Internet access only).

            I use a Weller XP30 rated @ 800 degrees, with a fairly narrow tip. Does that seem adequate to you experts? Wish I could afford a bigger one, but maybe this will do. I will also dab a teense of resin on the mobo solder pads to assist in a quick melt of the old decrepit solder. I also use solder wick instead of the sucker. Any opinion on these technicques would be appreciated.

            Anyways, thanks for all your help getting me back on solid ground from the afore mentioned "warm" location.

                Finally, I am back on course.

                Thank you so much for your help! My solder iron worked just fine and I feel I can get the the recapping job done just as soon as I can afford to get the caps from you folks.

                  Re: I am in Emachines and Compaq hell. Help me get out

                  I have several eMachines that were left on my doorstep by clients. All had the Bestec PSU installed, none of the boards survived.

                  I have one nice one, 3.0 GHz, 200gb SATA, 1gb ram, that looked like it might survive, so I recapped it. It worked for awhile, and now won't power up at all. Pity, to waste away all those Rubycons on a corpse.

                    Wow! I guess E would be my last choice on a new computer. Short of becoming a DIY computer builder, is there any hope for a good generic Computer at all? My husband says Compaq (now HP) is supposedly highly improved but I'm not willing to trust his opinion after my last hellish adventure with Compaq (now a "Frankenstein" - after PSU, CD, + floppy failure). Dell seems to suck as well. Any suggestions for which one of the biggie computer MF-ers Santa should bring me?
