|PSs can damage the mboard or anything connected to the mboard while failing or when they have failed fail completely. The more el-cheapo the PS is, the more likely that it will damage something else while failing. |
If the drive controller error is for a connection to an actual drive, try disconnecting the data cable connection to the drive at the mboard SATA header, or at the drive end if it's IDE, try the computer with the drive disconnected that way if possible, and/or check the data cables.
Check the data cables and the pins on the drive at both ends for evidence of damage. For that matter, check all wiring connections and drive pins and the contacts on cards in slots and on the ram modules in their slots for evidence of damage.
It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittent, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.
Try another data cable if in doubt.
Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)
The same thing applies for the SATA power connection.
You could try un-installing the NVidia "drivers" and installing them again.
Sound and video "drivers" always have associated files that must be installed properly along with the actual drivers. If you install only the actual drivers, it's likely the device will NOT work properly.
Unless the instructions for installing a device tell you otherwise....
(this ALWAYS applies to video and sound adapters )
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
The same applies no matter when Windows finds New Hardware !
If you DID install drivers that way,
(The following also applies if you want to un-install previous software, or re-install the same software)
- for video "drivers"....
- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting, let the desktop screen fully load.
Install the video software properly by running the proper download you got from the web, or if you have the CD that came with the video card that's in a slot, or if you have the CD that came with the brand name computer that has the Drivers on it, run the video software installation from the installation program on that.
for sound adapter drivers...
- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting.
- go to Device Manager.
(e.g. RIGHT click on My Computer - Properties - Hardware - Device Manager)
If the sound adapter is still listed, RIGHT click on it and Un-install it.
If that was there, and you un-installed it, Reboot at least once.
DO NOT install drivers while booting.
Install the sound software properly by running the proper download you got from the web, or if you have the CD that came with the sound card, or if you have the CD that came with the brand name computer that has the Drivers on it, run the sound software installation from the installation program on that.
