I recently connected a crt monitor to an old rig. It works fine up till after the windows boot screen (ie. logon)...where it loses its picture and is black. Turning it on then off will make a big "No Signal" Show up! I can get into the PC however when I use VGA mode (F8, like safe mode which also works). I have got the latest forceware in vga mode and still no good in normal boot! Also change the res or depth in VGA mode will cause the screen to go black and the light orange!!! what must I do to make it work...or get a res. above 1024x768 in VGA mode?

btw...the gfx card on this system is a ABIT siluro Geforce 2 MX440

thanks in advance

This looks like a classic case where the system can show the BIOS/POST and the generic VGA driver, but as soon as the video driver or accelerated AGP mode is enabled the monitor loses sync. Since already covered refresh-rate problems and has tried driver reinstalls and posted the AGP-install error, focus next on the chipset/AGP path and hardware isolation rather than just the display settings.

From the VGA/safe-mode prompt, try these prioritized steps:

  1. Clean the video stack: in Safe Mode uninstall the NVIDIA driver and the monitor entry, then remove leftover driver files/registry traces (use a trusted “driver-clean” tool or manually remove Display adapter entries after a System Restore point). Reboot and install a known-stable legacy ForceWare for the GeForce2 (do a clean install instead of upgrade).
  2. Fix AGP/chipset support: the AGP-install error suggests the motherboard chipset/AGP driver is the weak link. Identify the motherboard/chipset and install its chipset/AGP drivers (or try a different AGP driver package). In the BIOS try lowering AGP speed or disabling AGP-specific options (fast writes, AGP 4x → 2x) to see if the card becomes stable.
  3. Hardware checks: reseat the card, clean the gold edge, and try a different VGA cable or a different known-good monitor/cable again. If possible test the MX440 in another PC or fit a different AGP card in this machine — if the problem follows the card it’s likely a failing GPU/VRAM or power issue. Also consider PSU capability: when the driver initializes the card draws more power.

If those fail the likely culprits are a bad card or incompatible/absent chipset support; post the motherboard model and the exact AGP error text (not just the screenshot) for more targeted steps. Back up and make a restore point before driver or BIOS changes.

It sounds like you've set a resolution and/or refresh rate the monitor cannot support so it is forced to drop into standby mode. Find out what refresh rates it supports (perhaps start with 60Hz for the moment - you can try out higher rates later with Windows switching back after 15 seconds) for the resolution you want and change the setting in safe mode (refresh rates are changed under Display Properties->Settings Tab->Advanced Button->Monitor Tab). If that doesn't work, try uninstalling the video drivers in safe mode, reinstalling after a normal Windows boot and then changing the display options before restarting.

thanks buddy...but its all been done before. 60hz is the only mode it supports, and i can only change the res in safe mode.

i have also done the un/re-install drivers routine for the monitor and gfx card and nothing!

Is this Windows XP? What model is your monitor?

Member Avatar for marceta

Windows XP pro.

Hyundai Imagequest V770

i have also tryed with an old Packard Bell monitor!

this might be of interest. When im installing the updated AGP drivers i get this. But windows (device man., and disp. properties) recognises the Card!!!
