I have just attempted my first PC build.
All components are new and reasonably high spec.
Windows Vista Ultimate 64-bit
CPU - Intel Core 2 Quad Q9550
MOTHERBOARD - Gigabyte GA-EP45-DS4
RAM - 8gb (4x 2gb) G.Skill PQ Series PC-6400 DDR2
GRAPHICS CARD - Palit GeForce 9800 GT
POWER SUPPLY - Tagan TG-800-U33 Force II v2 800watt
HARD DRIVE - Seagate Barracuda 500gb w/32mb cache
The system seems to work fine using the standard VGA graphics adapter.
However, if I install the most up-to-date 64-bit vista driver for the graphics card, on a reboot:
- all starts fine
- the copyright Microsoft notice comes up with the progressing green stripes
- the usb peripherals start to power up
- then the power momentarily reduces or goes off (you can hear the fans power off for a split second) and then the screen goes blank
I can only get the system working again by starting in safe mode, rolling back the graphics driver, and rebooting.
Does anyone have any thoughts?
