Other:

I have disabled the onboard SATA controller, since I donot have any SATA drive. I disabled it a few minutes ago.

I have XP installed on a separate hard drive, and its licenced. After I installed Vista, I am suffering from unexplained random freezes. And I cannot pin point the application responsible, even if there is one. It sometimes freezes in IE, in FF, or in some other application, so I can rule out any application specific conflict.

I have disabled all USB mass storage devices, coz I have seen the earlier beta versions going belly up with USB mass storage device.

Is there any work around, or what am I doing wrong.

Some Errors that are being shown on my Event Log (its random)

1. IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 2, function 0. Please contact your system vendor for technical assistance.

I donot know if that is the problem. The PCI Slot 2 houses the TVTuner card. The machine freezed just now, while writing this post, I saw the Event Log, there was no Error.

The machine randomly freezes and unfreezes on itself. I think have to take it to a Tantrik Baba for jhar fhook.

1 way of finding out a solution is to 1 by remove all add-on cards including ur nvidia and then c if there is any change in performance ... if my guess is right the problem is not with vista but there seems to be a hardware conflicting with something

remove all cards .... then c if it wrks properly ... then 1 by 1 put all cards back and then see
