my PC starts to restart by it self after I installed second PCI graphic card
Posted on 2008-10-23
I have a problem guys, 6 month ago I built a PC with
320 GB HDD
Gigabyte motherboard(AM2+ 940) MA770-DS3
AM2-940x2 Dual Core 6000+
Gigabyte graphic card PCI-E 512 MB 8500GT - Nvidia
4 GB RAM
and the PC was working fine and I use it for the church, so on the graphic card I connect a monitor and on the DVI I connected a projector to display songs.
then last week I decided to get another Projector as foldback for the singers on the stage, so on my Motherboard has only one PCI-E so I searched the internet and I got a PCI graphic card Radeon 9250 64-bits 128MB and I installed it and since then the problem started which is my PC start to restart by itself, so I thought it could be bc of a conflict between Nvidia & ATI chipset.so I bought another PCI-E graphice card 256MB Radeon HD2400 pro and I installed it ..so now I can see both of the driver on the display settings ( which I couldn't first with Nivida to see the driver for the PCI ) but still restarting..so may be the power supply so I bought a power supply ..still restarting ....so I decided to formatt my PC..so I kept the PCI-E HD 2400 and formatted my pc ...all good and tested it for hrs...once I installed the otherPCI card starts again to restart...I made sure I have the latest updated driver from ati.com for both of them...but didn't make any different.
so really I need your help guys...what is wrong ...I need to use another projector..and I read a lot of articales about people using 4 monitors and they are having 2 graphic cards
Thanks so much in advance
