Re: p35-ds3l

Well, i'll try to answer all your questions. The graphics card is noisy at startup because it spins the fan at 100% to make sure it is working properly.

Then, nvlddmkm.sys is the nVidia graphics card driver. It has nothing to do with your motherboard, you may have a faulty graphics card. Ask in the nVidia forums to make sure... And you said you suspect the power supply. However you haven't told us what power supply you have.

Re: p35-ds3l

I would suspect the power supply too. I used to have a TT 430W and it was dodgy. I recommend Seasonic, Fortron (FSP), or Enermax.

Re: p35-ds3l

do you have any program to test or to vadilate what is the problem

Re: p35-ds3l

I suspect PSU as well, or crappy drivers. Did you try older or newer ones?

As for your fan spinning at startup like it does, that is normal and it is called spinup. GFX cards to this to ensure it is fully functional, all of them

Re: p35-ds3l

Re: p35-ds3l

nvlddmkm.sys is a Nvidia Driver error, caused by faulty drivers, or faulty cards.

Switch it to an ATI Card and you will be good to go

I am not sure what your mean by unplugging your PSU causes this, is it clearing the CMOS and loosing BIOS settings or time when you do so? If so you need a new CMOS battery

Re: p35-ds3l

mybe
because the problem came when the windows 7 loading

Re: p35-ds3l

ATI Card, or new or old drivers is probably your only fix.

PSU is really not the issue

Re: p35-ds3l

I doubt that it has anything to do with the power supply. nvlddmkm.sys is one of the files for the video card. The fan on the video card will run at full speed until the Windows video driver is loaded. There is something wrong with the driver, or it's corrupted on the HD, so the fan runs at full speed longer. The first thing I would do is download the the latest Nvidia driver and install it. If this fixes the problem I would run chkdsk to make sure there are no other corrupted/bad sectors on the hard disk.
