New graphics card, now PC won't boot up at all

  cyberphobic 17:43 08 Jul 2007

My PC has a Gigabyte GA-7N400 Pro 2 mobo with an Athlon 3200, IGB RAM with 2 SATA HDDs - an 80GB with XP Pro and a 200 GB with Vista Ultimate. The intention is to dual boot and I have just fitted an nVIDIA GF FX5500 256MB graphics card which is Vista compatible. It came with no software which I was intending to download, so when the desktop came up, the resolution was very low (800 x 600)and as I moved the slider to the right the display disappeared. I rebooted but still no display, I refitted the original graphics card but still no display. I then removed the CMOS battery to reset the BIOS - still no display, and now I'm getting all sorts of questions on boot up about RAID and arrays which I don't understand . How could something so simple have resulted in all this? Would appreciate some suggestions to help me restore my PC to norml working order.

you should have downloaded the driver for the new card first and saved it to desktop, then installed it whe the new hardware found wizard started. if you deleted the old cards driver you will need to reinstall it for it to work.

citadel, appreciate that you may well be right, I was relying on the new hardwate wizard to do that for me automatically. However,I didn't delete the drivers for the old graphics card, so that doesn't explain why it won't work now.

have a look in device manager and see if there is a yellow mark at the graphics card. or click update driver and windows should find the driver as you have not deleted it.

Boot into safe mode and reset the display

If the Chipset on the Motherboard is Via, it may conflict with NVIDIA cards

Thanks for your suggestions, don't think I've made myself very clear -I cannot get the machine to boot into Windows, so neither device manager or safe mode help. When the machine boots, I get a nessage saying pres Control G to enter setup utility and then press S to continue booting enter Control S or F4 to enter RAID utility, then verifying DMI pool data then Boot from CD then Disk Boot Failure, Insert System Disk and press enter
Think this is much more about SATA than graphics cards

Only two things I can think of, if you have been in the BIOS you may have inadvertantly enabled the RAID or something else, hence it asking for a driver or you might have knocked one of the cables, the SATA ones I mean when you were in the PC.

I must confess my total ignorance of RAID, SATA, stripes, mirrors and arrays etc. The PC was set for me by a local PC shop and has worked fine for 3 years, what should/should not be enabled re the above

does the new card require another PCI power cable.

One other thing probably worth mentioning is that if I try to boot from thr Vista disk I get a brief blue screen, before boot up fails
