DreamPC2006 died again probably because of usb port/plug misalignmenton pins.

Or do you mean you plugged it into another header which was not intended for USB? That is _usually_ right, but unfortunately there are(at least) two different pinouts for USB mainboard connectors, and the breakout units do not always fit. So do not rely on the manufacturers to do the thinking for you. for example: oldish msi k7tPro2-A 1 vcc 2 gnd 3 usbd3- 4 gnd 5 usbd3+ 6 usbd2+ 7 gnd 8 usbd2- 9 gnd 10vcc oldish asrock k7vt4A Pro 1 usb-pwr 2 usb-pwr 3 p-4 4 p-5 5 p+4 6 p+5 7 gnd 8 gnd 9 (missing) 10dummy I assume this has been resolved with an industry standard for USB 3.0? |

DreamPC2006 died again probably because of usb port/plug misalignment on pins.
I will tell you guys (and girls ?) exactly how this happened.
It's kinda stupid but somewhat logical at the same time, so conflicting requirements/logics: Circumstances which led to the death: 1. I had to build in the new usb card reader (unfortunately it had no floppy drive ?! ) 2. I had to remove the old floppy drive. 3. I was worried about motherboard death. 4. I was worried about harddisk death. So what I did was the following: 1. Remove the floppy drive/old card reader. 2. Build in the new usb card reader. 3. Take pictures with my new canon powershot sx50 hs. (I was confused about the card reader only have a usb cable and nothing else) 4. I left the new usb card reader unconnected because I wanted to make sure that the motherboard and harddisks were still working. I was worried that connecting the new usb drive would blow it up/cause damage. I wanted to check first if all the building didn't damage anything. 5. I booted the PC everything was working. 6. I shutdown the PC. 7. I tried to connect the usb plug... somewhat dark... while everything was plugged in... And that's when it happened. Wrongly connected 8. I boot up the PC. 9. I tried and read something from the card 10. I play some music or something. 11. One minute after boot... FREEZE/HUMMING sounds on receiver/speakers. And the thing I feared the most probably actually happened... it blew up the fokking motherboard. Not 100% sure, but it seems most likely cause of death. It happened after about 1 minute of operation/playing some music or so. Bye, Skybuck. |

This methology is the same way I program software.
I take it step by step. Unfortunately that methology apperently doesn't work to well with electronics... DEATH OCCURED ! NOOOOOOOO ! Bye, Skybuck. |

I also had more bad luck.
There were only 3 light bulbs working at the time... I bought 4 light bulbs, had to replace a few... Unfortunatel 1 light bulb had the wrong fitting... it was too small... packaging almost looked identical. Perhaps if all 4 light bulbs were working I might have had enough light to spot the mis alignment. Then again the high up on the ceiling... It's dark inside a PC... and the plugs/pins real tiny... really hard to get it right. I even had a super hard time getting the power connectors/leds connectors and stuff connected to the Old Pentium III 450 mhz... even with a light bulb right next to it... Next time I should take a small little lamp and place it right next to it... or just take PC apart again... but this risks more damage to harddisks if they inside... Perhaps me should be glad that at least my harddisks are not dead ! At least I hope so I am not really glad though... all this **** just because of one little stupid plug I now have to find either: 1. A new socket 939 motherboard for sale somewhere. or 2. A new motherboard + new cpu, hopefully memory compatible, otherwise new memory too, that could become expensive. maybe I should try and fix it as cheaply as possible... I kinda hate giving up on a CPU... this amd cpu... I would like to keep it working for historical reason ya know ! I can always buy a new PC in the future. Now I just need to find a dutch store with a socket 939 motherboard. Perhaps I will go for the asrock 785 motherboard... not sure if that will fit my PC needs... I dismissed it in favor of the 790GX not sure why anymore... might have to look into my own postings for that... Pentium III 450 mhz a bit too slow for surfing probably too low memory... it's a bit slow as well... but 256 MB just not enough for XP... even with more memory it would still be too slow... so not going to spent any more money on it sorry, little computer ! Saving my money for a new computer in the future... just need to get this one back online ! I guess I will have to read the 785 manual again to see what it's got and if it's suited... what I remember from it is it's more tiny and probably has some wireless stuff on it ?! Actually my memory is coming back to me... I think it actually uses different memory slots. So it could be useless... oh-oh... I'll just have to find me another webshop which has ASRock 790GX motherboard... that would be best... And then I have to make sure not to blow it up anymore ! Ouch ! Bye, Skybuck. |

Also one of the problems with these tiny power switch/led connectors is the
following: The plugs are black and so are the ports/headers. All that blackness makes it very hard to see how they are aligning up... And they are hardly shiny... so even adding light doesn't change much. There would need to be a shading difference or highlights to notice anything... but with total blackness it's just not there. So using different colors for these plugs/headers would be nice and make things a bit easier to see. How much more that would cost I don't know Bye, Skybuck. |

DreamPC2006 died again probably because of usb port/plug misalignment on pins.
I just came up with a hopefully good plan/experiment for the DreamPC... yes
still not done with it, because me not statisfied with the results so far. The last year or so... I put the fans on medium speed, and no dust filters, end result: CPU Heatsink full with dust ! Power Supply full with dust ! All passively cooled things were okish, slight dust particles but not to bad. Also fans full with dust. So new plan is the following, since I have two motherboards: 1. The coming year I will put fans on low speed. (If that aint working because of high temperatures I might set it back to medium speed, but low speed will probably be ok). If the system dies again because of cleaning operation in the future, then my final experiment will be: 2. Disconnect FANS from the front, and maybe the back too... perhaps leave big fan on, or maybe disconnect that too... and only leave power fan spinning... but maybe one back fan should be on... low or so... So the Antec 1200 would become an almost passively cooled system... there is plenty of room/air in it... so perhaps a modest airflow is enough to keep the CPU cool... and also the passively cooled GPU. If the motherfokker dies again because of overheat (probably not) or dust-related-cleaning the fokking thing will go into the waste basket lol. Then I will buy a new PC, make sure it can attach my new drives... and new PC should remain dust free as much as possible and be low heat as much as possible Hopefully the dreampc won't die with this somewhat open antec 1200 grid inlet... and hopefully modest airflow will not cause dust issues ! I think it probably will cause dust issues, so this means next PC must have a closed front to prevent dust from getting sucked in... Time will tell ! Place your dust-bets now ! Bye, Skybuck. |

450 mhz.... bin the heap and upgrade. Out of curiosity what size are
your HDD's? I'm assuming something that old is IDE? On 21/11/2012 21:48, Skybuck Flying wrote: I also had more bad luck. There were only 3 light bulbs working at the time...
