I have the below specs:
- ASUS M3A79-T Deluxe 790FX AMD Motherboard
- Acer P243WAid 24" Monitor
- AMD Phenom 9950 2.6GHz
- SAPPHIRE Radeon HD 4870
- Western Digital 640GB SATA Hard Drive
- CORSAIR 750W ATX12V Power Supply <<<---------
- CORSAIR DOMINATOR 8GB
- Thermaltake SpinQ Heatsink
- Lightscribe external DVD Burner (USB)
- Plextor internal DVD Burner (SATA)
- Linksys WMP54G Wireless
- Windows Vista 64 SP1
I have tried numerous times to make my brand new computer work but it seems to not want to cooperate. I know that the HD 4870 cards have an issue with LCD screens going blank in DVI mode after a while due to poor drivers but users state they are at least able to use the VGA (D-SUB) adaptor with success. I have no success in this at all. Not even my 22" CRT ViewSonic which can do 1600 x 1200 at 100Hz can make use of my new computer. The screen still blanks out or locks up.
My question is, is the power supply not enough or is it possible my video card is all screwed up?
Any suggestions will be greatly appreciated.
Oh to note my computer works in normal operation just not when it has to change resolutions and such or if it blinks momentarily, ex. when installing and the screen does a dim mode to verify user permissions.
