i updated windows xp and on re-boot i got a no signal input message.xp starts to load but ends on a blank screen.i have no graphics card installed and i've checked all connections of monitor etc.i can't even start windows in safe mode.i figure it's an update that has wrecked things so i was wondering that if i try to re-install xp will this fix the problem or am i wasting my time.is there another way i can atleast get windows running so that i can nut-out the problem from there,i've also heard that by removing the pc battery will reset the bios and that this may help,any ideas on this method and what if i don't have a battery to remove....any suggestions would be greatly appreciated...thanks ,Gary

Even the Windows install CD, but a Live CD (or live usb flash image) of some sort would be better. Something that runs in a GUI.

If you can boot and run the CD normally, with the expected behavior for video output, then it is probably some problem with the XP installation.

If you see the same problem running a live cd, it is probably your hardware - overheating, failing power supply, failing graphics, RAM problem, etc.

(Slax is a smallish image that can be put on USB as well - there are others.)

You are seeing the XP loading screen, but then the graphics (at least) fail?

hi
"i have no graphics card installed" - you mean you have no card, but onboard graphics?
why can't you get into Safe Mode when booting? - just keep hitting the right button (F8?) repeatedly while booting
can you boot into BIOS ('del'?) - you might check initial display is set to your adaptor
not an AGP card or w/e
I expect you do have a BIOS battery...dont pull it unless BIOS is scrambled - unlikely if this is an update issue
cheers

i have on board graphic.i can access thes f8 and del function.when in the f8 functions i chose safe mode and then the screen filled with all the system drivers etc and that was it,it went no further,like it froze.choosing last known good start just loads the first part of xp where the screen has the windows xp logo and then all goes blank.in fact in f8 nothing really works for me.it seems that the boot process has been corrupted somehow.so now what ?

Hold F8 after the BIOS boot screen is done and select Safe Mode, if you can't get into Safe mode this way try removing power from the machine while the loading screen is still running and then plug in and start the computer and it should come to an error screen stating that Windows had a problem during the last boot and would you like to start in safe mode.

I suspect a possible video driver problem and since Safe mode uses generic drivers it will help determine if this is the problem so if you can get into safe mode and are able to see the GUI then you should go out and get the newest video drivers for your PC from the manufacturer, uninstall the old drivers and install the new ones. This should correct your problem.
