Hi guys, got a computer here, was working fine, but now upon turning on the power, the monitor light goes green, for a couple of secs then into standby (orange light)... the computer beeps etc, so seems likes its booting fine... any ideas why this would happen??
yeah me too, i have theory about it! my young ears can hear a high pitched sound coming from my mobo.... yesterday i overclock it and change bios settings etc, turn the pc off, go to sleep and when i wake up its back to factory settings with the moniter driver broken, nearly every day! so i think its shorting out somehow. could this help? the way i plan to fix it is to get a GPU and use blind hope that that will in some way fix the moniter problem
Check your connection between monitor and graphics card; if you still have no luck, try swapping out your GFX card. If you've tried overclocking your machine (immediately before the problem started) then reset the CMOS and see if that helps. Otherwise your monitor is buggered, because afaik you can't really boot without a VGA unless you've got auto-onboard video... Hope this helps in some way.
Try booting the machine in VGA mode. If it works ok, then check into your GFX driver. I had a situation simular to yours some time ago, and that seemed to help.
Have you tried booting to safe mode and uninstalling the gfx card driver, then let it reboot and redetect the gfx card?
could be almost anything. Does it beep before the monitor cuts on? Does it beep after? Does windows start-up do its little trumpet? The best thing to do, while it is booting, cycle the numlock or the caps lock. Keep cycling them and see if they continue to work. If, at any point they stop working, your system is hung (use a PS2 keyboard not a USB keyboard). If your system is hanging, it is unlikely to be the video card. If you are convinced it is the video card, remove it and boot the same way (cycling the num lock). Try to see if it boots any further. Next thing to do, remove things one at a time (or remove everything and re-install them one at a time) and re-boot to see if it makes it further. With nothing attached but a video card (and keyboard), you should be able to get into BIOS set-up. If you can not get into set-up with only a video card, then its either your video card, memory, CPU, or MoBo. But if you make it far enough to get a little video, its probably not the CPU or memory.
Could also be that the mobo is set to look for a PCI videocard first. Thats might be why there is a delay before the video kicks in. Or it could by your using a PCI card and the board is looking for AGP.
This would have to be a real crappy BIOS for this to be a problem. The BIOS should not care if you have a hundred PCI video cards and an AGP card. It will just use some logic and pic one, then completely ignore the others.
What delay? how do you know? Of course it is possible, but it would be a silly way for the BIOS to behave. Rather, what it should do is go through every address on the root PCI bus and record each device it finds. Then, if it finds other busses, go through them the same way. When it does this, it will simply make a list of everything it found. Then later - probably 1,000 lines of code later, when it decides its time to display some video, it will go back through the list it made and decide which video card should get control. This is what a mainstream BIOS does (AMI, Pheonix, Insyde) - some little tiny BIOS company may do something else, but it would be way way way inefficient (like filling a bathtub with a teaspoon). Searching through PCI space is a painfully slow process and the BIOS should only do this once and it better record everything it found on that search. It will take just as long to search PCI space if it finds no video cards as it will if it finds 100 video cards. Soooooooo - it should take a second or two search all the PCI space (including AGP). When it actually "searches for the video card" it only needs to parse a little table listing every device found earlier. This will take a tiny tiny miniscule fraction of a second (like 1/1000th the delay between when you hit a key and the appropriate letter appears on the screen). Honestly though - once the video gets control, the video driver will usually display its own screen right away. So, on consideration, the fact the monitor is getting power but no driver signature screen is displayed, makes me say (as others have already said) - the video card is shot (or possibly in a bad PCI slot).
