Gateway FPD1975W only works in safe mode

[ladalet]

I recently replace the caps on this Gateway FPD1975W. It was not powering on at all. After replacing the caps it would power on and lose the signal as windows began to load. It would go into safe mode and work fine. If I uninstalled the ATI video driver and used a generic video driver it would work fine. I uninstalled and reinstalled the ATI driver and it worked until I attempted to raise the resolution over the 800X600 or attempted to change the color from 16 bit to 32 bit. The installation defaulted as a plug and play monitor at 800X600 16 bit color. I had to uninstall and reinstall the video driver to get it to work again.

I tried the monitor on a second computer with the same result

I then tried an analogue VGA cable with a DVI adaptor and it worked fine. It detected as a plug and play monitor and defaulted to the correct 1440X900 Resolution 32 bit color.

Additional information.

I replaced the following caps
4 x Rubycon 220uF 25v 8mm ZLG Series
5 x Rubycon 470uF 25v 8mm PX Series

I accidentally ordered 470uF 25v 8mm caps instead of 470uF 25v 10mm. I installed them anyway. Can this be the problem and or could it lead to any other issues if not this one?

Thank you in advance.

Did you replace any of the caps on the main board?
My GAteway 2185 had 3 bad caps on the main board as well as the bad ones on the power supply/inverter board.

No, I only replaced the caps on the power supply.

Some new information: The monitor works not only when in safe mode but also in VGA mode, normal mode with generic VGA adapter drivers installed, and works perfectly plugged in with a VGA cable and DVI adapter. With the VGA cable and DVI adapter the monitor even defaults to a generic monitor driver but the correct resolution (1440X900), refresh (60hz), and color (32 bit). I also installed the correct DVI inf file and loaded the correct drivers for the monitor. Now it lists the correct monitor drivers installed but not the correct resolutions--plugged in DVI. Further research suggests that the issue is a corrupt EDID EEPROM on the DVI side. I supposed it may have corrupted when the caps popped. Thank you for your suggestion.
