  • Opus, windows won't boot now.

    I am pretty lost with this one.....
    So my computer has the specs there in my sig. and a Biostar (can't remember the model) motherboard with onboard usb/network/video. With a regular power supply my computer loads up perfectly. With the Opus it restarts right when windows tries to load. When I try to boot it in safe mode it goes to the mup.sys file and then restarts... I have disabled the mup.sys (log into windows recovery console with other power supply) because it is supposedly some file windows uses to load multiple networking clients. I can't even boot off of the CD with the Opus power supply in there. It just restarts when you press the key to boot from CD.
    Anyone ever had this problem?... I have looked all over the internet and most people that have this problem, it is usually associated to their USB card. Mine is disabled as are all the other onboard components - the video card.
    THanks!

    I ran a repair on windows and I am still having the same problem. Boots up fine with my regular ATX PS but when the opus is plugged in it can't boot windows. It posts just fine but can't load windows.

      probably not enought juice.
      How many watt is the AC PSU? Try to use a 150W AC PSU to see if it the PC can boot.
      AMD XP 2.6K+ is way over kill. I was able to run an AMD XP-M 2.5k+ (45W model) with a mATX mobo with onboard everything on a 150W AC PSU.

        Are you sure an Opus 150W can provide enough power for your setup?

        The max current on the +12V rail on the opus is 6A (i.e. 72W max power). The max power dissipation of the Athlon XP 2600+ is 68.3W (see here). Add to that the power required by your mobo, 3.5" hard drives, cdrom/dvd drives and lilliput (if you are powering it from the opus) and you are very close to reaching the limits of the +12V rail.

        EDIT: nevermind, looks like MatrixPC beat me to it.

          I have the same setup except a P4 2.4Ghz and I'm having no problems... If you think the CPU is too fast then try under clocking it a few hundred Mhz.

            Thanks guys a ton for the suggestions!!!!
            Right now all I have plugged in is my HD 7200 RPM, my CPU, (I have tried 3 differant sticks of RAM with differant sizes and speeds) and the onboard videocard. I'm not powering my lilliput or any usb devices at the moment with the power supply. The AC PSU I am using is 250W and at the moment I don't think I have a 150W AC PSU. I will look around and see what I can dig up. I will try and underclock the cpu and see what happens.

              Ok, just tried underclocking it. I changed the freq. to 100 and it loaded windows just fine. Put it up to 133 and it loaded windows just fine. Put it back to 166 and it loaded windows half-way ( a lot farther than before) and then restarted.... I know my cpu is way overkill but it is all I had laying around... I thought that the opus should have been able to handle what I am running. Especially when I have everything unplugged/disabled. Don't know though... What do you guys think?

                You should be able to plug in your USB devices and laptop HD without any problems since they use the 5V rail. The only things that will affect your premature shutdown problem is the CPU, 3.5" HDs and/or cd/dvd drives. Clearly, the culprit is your CPU drawing too much power on the 12V rail since it works fine when you underclock it. Like I mentioned before, the athlon xp you are using is already dissipating close to the peak power output of that rail.

                  Cool, thanks for the help. I will just keep my proccessor underclocked. Won't make much of a differance to me and hopefully it will last longer underclocked.

                    Well, it'll be cooler - that's why my Athlon XP-M is underclocked to 1.6Ghz.

                      Hate to resurrect such an old thread, but I guess that's what I get for doing a on

                      Anyway, I misread my Celeron 2.4GHz Opus 150's specs thinking it would be enough but it wasn't. My CPU draws 58W (thought it was 50) and the Opus 150 for the Shuttle XPC outputs only 5A (not 6) on the 12V rail. So needless to say I'm running into power issues.

                      I'm right on the threshold however - it will boot from a start and run fine for hours most of the time, but if I try to reset it (or shut down and restart w/o waiting a looong time), the HDD won't spin up. Sometimes while running the video will drop too.

                      So I'm looking at underclocking (which is how I found this thread) - does anyone have any recommendations? I've never under/overclocked a CPU, and haven't manually set clocks and multipliers since the days of jumpering them manually on the board. Should I try to lower the clock from 133 down to 100 or should I play with the multiplier? Doesn't really matter to me which would be more/less performance, I've got plenty of GHz to spare for the function - it's just what came cheap in a nice small formfactor. I just want to keep the thing stable and drawing as little power as I can - right now I only have my HDD hooked up (and don't really want to go to a 2.5" 5V drive because I'm using a good chunk of my 250GB 3.5").

                      Any help would be appreciated. Thanks.
