that I put together has an ABIT board and the same symptoms you are having, I was using An ATI Video card also. My board has the Nvidia chipset and the ATI card would not work with it so I installed an NVIDIA video card and all was well. Not saying that is your problem but is you have another Video card give it a try.
hi guys im new to the forums. my prob is I have a new motherboard Abit as8 3rd eye it is an intell board of which I have installed a lga775 640 3.2 ghtz cpu. I transfered my ide 40 gig hdd and my maxtor sata 80 gig hdd, plus my giel pc3200 ram 768meg I have a radeon x800 pro agp vga card which was also in my previous system. I reformated my ide 40 gig drive as i use it as the master and i reinstalled windows xp professional every thing ran smoothly windows installed and I then installed the chipset drivers for the motherboard. I then noticed that my sata 80 gig drive wasn't in the my computer list I went into disk manager and it was there and it said the drive was fine. I figured the reason I couldn't see it was cause I must not have installed the sata driver. so I shut down the pc changed the bios to boot from the cd rom cause I was going to use my windows setup to install the sata driver from the floppy disk. only when it said press any key to boot from cd I missed it and it went straight on to load windows. here is the problem happened when windows loaded it was really distorted and all the wrong colors I shut the computer down by depressing the power button then when i turned it back on again nothing I have no display I dont get the beep code error saying theres somthing wrong with the video adapter infact I dont even get the single beep that i usually get. I first checked that the video card was properly inserted which it was I unplugged the monitor and pluged it in again 2nd try again nothing happened. I shut the power off completly including the standby power then I reset the cmos nothing. I then tried my previous vga card a radeon 9600xt and nothing happened. I then swapped monitors when I turned the computer on I saw the monitor fire up with a green light then it quickly shut off back to standby just b4 i got a picture so the problem is not with my video card or my monitor but it is a graphics problem as I said the motherboard is brand new has only been turned on twice which was when I reinstalled windows. so there is nothing wrong with my agp slot. I was connected to the internet at the time when windows first loaded is it possible i may have caught a virus if so is there such a virus that shuts down your monitor? if so how would i fix it? I cant really think of what else the problem could be I really hope somone here can think of somthing. also I hadn't got around to installing the video card drivers b4 this happened.
any help would be greatly appreciated thanks guys
