Hi all

I recently bought a new processor, motherboard, memory and graphics card. when i recived them i pluged the motherboard, processor and memory in to my current case and psu with my old PCI E graphics card to make sure they worked. They all fired up first time and worked, i looked at the BIOS to make sure they where all running ok and they where. today i bought a new case and a PCI E power cable as the new graphics card i bought requires one. i swapped every thing over in to the new case (hard drive, floppy, cd/dvd drives and the new graphics card, mother board, memory and processor) i plugged the power in and tried to turn it on but computer did not work it just made a funny noise. i figured it may be the graphics card hogging all the power so i unplugged it. after i had taken the card out and i tried to turn on the computer all the fans in the computer (front and back of case, PSU and CPU) would spin for a second and then go off. i thought the case my be causing it so i took every thing apart and just had the motherboard and memory. however still the same, the fan would spin for a second and then nothing. if i held a screwdriver over the power on pins for a few seconds they computer would power up or so its seems as all the fans are spinning, but the computer does not work still. no sounds or visual output. all i can do now is make the computers fans spin for a second and then go off, get the fans to stay spinning by hold a screw driver over the pins. one thing that i have noticed is that if i plug the PCI E power converter in and the graphics card the computer will not do anything at all, it just makes a weird noise. if i dont use the power cable and just have the graphics card in it will just spin the fans for a second and then go off. I have tried a new psu, took the memory out and started it to see if it beeped (it did not beep or anything just powered down or got running if i held the power pins for a few seconds), tried a different graphics card and it was still the same where as it worked before but i just cannot determine the problem. it all worked fine before i swaped cases and put the graphics card and the PCI E power converter in and my old hard drive, dvd/cd drives adn floopy drives. but like i say when i take it back to just the new parts it wont work at all now but it did before. a few friends have said that its most likly the motherboard. Dam thats one long post, Any way any help or ideas appreciated, cheers Max

Hi Max,
If you are absolutely positive the pinouts are correct and you've tried another WORKING PSU
ram, there are no POST errors etc, try either ( this will **** you off ) installing your old mainboard in your new case (to eliminate the new case) or your new mainboard in your old case (to eliminate the new mainboard)
Good luck

i tried swaping them both in the cases this morning and the only thing i have noticed now is that if the power button is pressed the fans will spin for a few seconds and then nothing. if the power button and reset button is pressed the computer seems to start up (all fans are spinning) but it does not doing any thing, no beeps or output etc. i tried phoning the shop i bought it from today but they are all on christmas break till january, i just cant think what could have made it suddenly not working by swapping cases. im sure the PCI E power cable i bought is causing some thing though cause the fans will spin on the graphics card if i do not add the cable but if connect the two power adapters to the PCI E six pin power and plug it in when i press the power there is no response at all.

one more thing i have noticed is that if i plug the components in to the new case the case and hard drive both make like a grinding noise? so many dam errors, cheers Max
