  • Computer problems

    OK, some opinions please

    My computer doesnt like the cold. Seems to be OK in summer. Lately, failry noisy start up and froze at startup usually at the log in screen(Win XP) and then often again once it logs in. Once it warms up, it is OK - I can reboot without crashing at startup.

    I thought power supply at first as because of the fan noise and the coldness factor. Replacing the PS didnt help. The noise comes from the CPU fan but I cant see that as a problem as it is OK when it warms up.

    So my list of suspects are:
    - hard drive. Ive installed Win 7 on it (but didnt reformat first). I dont think this is it.
    - dodgy memory chip: this is what I suspect is the culprit.

    Any thoughts. Only locks up when starts up from cold.

    Buy a heater? ;D

    Could be anything as it sounds like it might be a bad solder joint somewhere. My bet it is the mother board.

    Could try changing operating systems as it gets cold when the windows are open. err bad joke.

      To me it sounds like a bad memory stick. You going to have to try the old process of elimination with this kind of issue.

      Also if you want take of your cpu fan and give it a good clean and then spray a little grease and the noise should go away.

      Cheers,

        My bet is as per bassway... MOB on teh way out..


        Have a look at this and then ya MOB.

        Yes... Life can be extended in some cases if only one or two faulty caps..

        1: Cut the dead ones out... Those that are going short..

        2: Cut the dead one out and leave enough of the legs to attempt to solder connect a new cap to it. Desperate measures as the solder ( the legs of the old cap are coated and often the ends are that which have been crimped to teh guts of teh cap... Does not take to solder) and space available can make it difficult.

        3: Do not attempt to de solder... Multi layer boards and a good chance you will stuff it ASAP.

        Let us know how ya go.

          Thanks guys. Jokes aside (you need a new writer BW ;D ) I can see how the motherboard could be a factor especially from the cap plaque factor in AMs link. Perhaps a dodgy memory chip would be more likely to fail as it heats up.

          I dont think Ill stuff around trying to work out which caps are faulty and Im nowhere near good enough at soldering for such a delicate job even if I do leave legs. Ill invest in a new mobo.

          Yeah, Ill definitely get a new CPU fan IB. Ive measured a CPU temp facilty for my Asus Mobo and it reports about 63 degrees at start up and then drops back to a normal op temp of around 57 degrees.

            Just have a quick look... If ya have any that look like the tops have pooped up etc... Then that is a contributing factor.

            63 and even 57 is a bit hot for my liking..

              Cheers

              Had a chat to a colleague and he told me to look for bulging caps.

              60 is the threshold on the CPU temp monitor He agreed that the CPU temp is probably too high so Ill grab a new fan and some silicon paste and try that first.

                Also try just removing the adaptor cards (including the video card), cleaning the contacts and replacing.
                Probably do the same with the memory chip/s.

                Could be a quick and easy fix.

                P.S.

                  As I said... CAPS are popping..

                  This will also cause heat issues... Due to the lack of regulation on the power supply to the MOB components and CPU.

                  1: Check to make sure ya FAN and cooling fins are clean... Bet they are all very dirty with fluff and skin deposits. Dirty fins will had 10C no problem at all...

                  2: Si past and a new fan will do little..   Need to lap the CPU and Heat sink and use as little heatsink compound as possible..  (Silver past is best)  This will drop another 10C

                  If any caps are popping / bulging.. Then every thing else is a waste of time.

                    Re: Computer problems

                    Remove hard drive and other peripherals you know are working take the motherboard outside with the addition of a little petroleum and a small flame stand back and smile at the reversal of pain and suffering You are causing to your former PC. Then make a short and low stress trip to your local PC supplier.

                    Last motherboard problem I had (tried a new power supply and a clean first) I did pretty much as above, $350 for a brand new box for the office minus a few bits and got to keep my sanity. That included re installing the bits and setting it up. Still have the old case and I am going to put my old P3/win98 in it.

                      Just confirming what you said AM, not ignoring. I already cleaned all the fans - CPU and graphics card while I had the box open.

                      I like your thinking BF. Ill take a gamble on the CPU fan first.

                        So do any caps have popped or bulging tops.. ???????

                        PS. Laping the CPU / Heat sink guide......  http://www.techpowerup.com/articles/cooling/air/39 and here http://www.overclockersclub.com/guides/lapping/

                        I use my own method... Note: Less is more when it comes to the transfer compound.


                        If so; fans etc are not worth the effort.

                          Im not at home at present so I dont know.

                          Ill check out lapping later. After checking the CPU fan on the weekend, whomever added it the first time did a lousy job and I wont be getting him to build a computer anymore.

                            The super nerdy techs at where I work tell me that the transfer compound is actually an insulator. Transfer is a bad term.

                            The insulation properties are far less then air though. So as the link that AM provided shows the compound is to ensure a smaller to non existent air gap between the device and the heatsink therefore better heat transfer.... I think I just contradicted myself.... ;D
                            Well "Transfer compound" is a bad term if you dont know what is going on.

                              ROFLMAO..  bassway.. Ya right..  Many just plunk it on.. It has better conductivity than air... Thus the Silver is good, but of course the less ya need the better.
