i have asus k53sv with no display changed the bios gives display but does not take any display drivers i have changed so many bios also when i install windows 10 it take standard graphics drivers and in windows 7 device manager/display adapter it i get exclamation mark on intel and ati say there are no resources to start the device.where is this problem bios.

K53SV does not have ATI video, it has NVIDIA, you have identified the computer model incorrectly.

sorry i made mistake it is nvidia so it takes no drivers at all but windows 10 works well it take standard drivers. where i the problem

K53SV ver 3.0 is motherboard model, not computer model.
Same motherboard goes to different models, so computer model can be different, check the sticker text on RAM slot.

if computer model is really K53SV, then original bios is here: viewtopic.php?p=741139#p741139

hi thanks for the bios i have put the above but same problem i get display and the screen looks 8bit display does not take and drivers i have changed bios drivers still same issue but now i understand in device manager the display adapters for nvidia and intel show no resources available also the lan on board shows no recources what i understand is that the devices are not getting irq interrupt and io memory so does the interrup controller is handle by pch inel hm65 or ite8752e lpc serriq lpframe as there was corrosion on the micom i resoldered it but still same issue.can any masters tell me what i should be changing thanks for all the support.

Try to write more understandably, now everything looks like one sentence without any start and without end.

Did you determine the computer model correctly like I said? Sticker on RAM slot, or text on the back of computer case.
K53SV ver 3.0 is not computer model.

I am saying this because maybe you need other BIOS, not K53SV. The same motherboard goes to different computer models.

so which is the other one i have tried 7 times different bios and if i put it in the programmer and flash it is on but when i flash to new in windows the system goes dead after flash

You need to read what I wrote.

And write sentences more clearly, use "," and "."

And answer my questions. Otherwise it is a waste of time.
