Multi CPUs Not Shown

I just did a clean install of Windows after having unusual instabilities and
operations after upgrading my MoBo, memory and processor. I was hoping to
cure the instabilities that had been seen but I am still having trouble after
the reformat and reinstallation.

It is not clear if these issues are connected so I will list them.

1. On rebooting sometimes all four of the processors in my PenomII X4 920
are shown in Task manager (properly) ... other times only one processor is
shown and the system is noticably slower and more heavily loaded per the
performance tab in Task Manager.

2. Sometimes my displays "hiccup" on about 4 second intervals ... sometimes
they are stable (normal). I have two displays running on the MoBo's internal
Radeon 3200HD chip set, one on the DVI and one on the SVGA connector. (I
have updated the drivers to the latest from ATI) By hiccup, I mean that the
entire window jumps about 1/8 of an inch in the vertical direction and a few
lines of blue are shown at the top of the displays. This does not seem to
happen during BIOS polling but begins immediately when the Windows logo
appears during the boot process. Changing display refresh rate or resolution
also changes the frequency of the hiccup but does not correct the problem.

3. Occationally my system hangs and becomes completely unresponsive to the
keyboard or mouse and must be rebooted.

As indicated, I thought that these might have been due to some issues with
the HAL after the upgrade from an Athlon 64 X2 4200+ and ECS MoBo. So I "bit
the bullet" and did a complete reinstall of XP and MoBo drivers, etc. after
formatting the hard drive.

I have checked the BIOS for settings that might determine the number of CPUs
recognized or the timing of memory or video display operation. All are set
for "nominal" or "auto" and the processor seems to be recognized during
system post and in the properties of "My Computer" even when Task Manager
does not display all four CPUs.

Any suggestions would be welcomed.

Have the motherboard/CPU replaced - one or the other (perhjaps even the
memory) could be defective.

Then again - how big and how new is your power supply?
