Hi.

I uninstalled my video card driver in device manager, my computer went to default video. I then tried to install different driver and it said something like "No compatable hardware found". I rebooted to a black screen, even on POST. I can hear windows loading fully but not even a flicker on screen. I've tried booting with external monitor (DVI), pressing Win-P when windows was loaded, tested HDD in desktop, reseated RAM and checked all connections. I can't remove CMOS battery as it is soldered to Mobo, so i shorted it out for 24hrs, still the same!!.

 

My question is, if i take out my graphics chip from Mobo and reboot will it help me, or just make things worse?.

 

Thanks in advance for any help

Have you tried booting into safe mode to see if it will trigger the default video to kick in?

Thanks for your reply chrisd87. I have no idea which key to press, i have  tried some "F" keys and key combinations, but to no avail. My thinking is the Mobo maybe has some sort of boot order and thinks i have a graphics card installed, so by taking out the chip it might force it to use default.

Typically it's the F8 key that you press constantly, and then select the first option to boot into safe mode. If you have no display at all, not even at post then it may be hard to tell. I wouldn't mess with the graphics chip as it may cause more problems than good.

I'll google it and try the keys again. Thank you

did you have a video card originally? If you have two video devices available you need to remove one, easily the add on card. The computer will always primarily load the add on card before onboard. Only by removing the add on card will it revert back to the default onboard video.

Thanks for your reply Netghost56. No, just the 8600GT and as you can imagine it's quite a big job to remove it, in the hope it will default. I have no problem stripping the laptop and removing the card. But my limited knowledge of what the end result may be makes me hesitant to proceed.

Net, he has a laptop like he mentioned in the op. Have you tried the F8 hotkey to see if you can boot into safemode and kick in the default vga? If it's not the F8 key, did you google it to see which key enables safe mode?

I've tried every F****** key. lol.

I tried keys and key combo's for any brand i could find that uses the ILF90, i don't think i got into safe mode and if i did , it didn't work. I use a fingerprint scanner to log on so i know when it's booted normal because it's disabled in safe mode. Do you happen to know is there any disc or software out there to maybe reset my bios, force it to default, load drivers or something?

 

I'm going to put a newly formatted HDD in and boot to windows install disc, try do a blind install, maybe it will default. I really don't think that it will work, but i'm willing to try anything at this stage.

You can try Hirens boot cd. That will clear the bios for you. Don't know how you would get into it though. I don't know of any software off the top of my head or google search that will clear the bios without needing to see the screen.

 

Just a thought, but have you removed the battery- held down the power button for 1 minute, reinserted the battery- press power button   to see if it will power up?

 

Here is a guide to help you reset the bios on a laptop.

Thanks

He means he reflowed it, heating up to oven temperature, which will partly melt the solder and allow it to reweld itself.
