Gforce 2Pro: Pixels remain on screen

[savas]

I recently changed my hardare.
After reinstallation of Windows2000Pro - SP2, and the latest drivers for the motherboard and video display adapter, I changed my resolution to my preferred settings (1280 X 960).
Working on this I noticed that sometimes sparkling pixels remain on screen. This is weird as I had not these kind of problems before.

Install the latest via drivers, change in bios
AGP to 2X and latest W2K Nvidia driver.

The hardware change was motherboard / CPU / memory and hard disk combination.

Current System:
Motherboard: Gigabyte 7XVR
CPU: AMD XP1800+
RAM: 384MB DDR PC2100 (Kingston)
VGA: Nvidia Gforce2Pro
HD: 2 X 80 MB Maxtor ATA133
DVDROM: Hitachi
CDRW: Plextor 1610T
NIC: 3com 905C
SOUND: Creative Soundblaster Live 5.1
plus ISDN Terminal Adapter, Firewire (Pinnacle Studio DV)

Previous System:
Motherboard: MSI K7Turbo-R
CPU: AMD 1Ghz
RAM: 512MB SDRAM133
VGA: same as above
HD: 2 X 30GB IBM Deskstar DTLA
in RAID-0 with the onboard RAID controller
DVDROM: same as above
CDRW: same as above
NIC: same as above
SOUND: same as above
plus ISDN-TA and Firewire as above

I would like to add that the
system in both configurations
had a 350W PSU and a Sony 19" monitor.

Thanks in advance for anyone
who takes the trouble to reply.
