LOL... this PC never ending problems.
Anyway, I've gotten a spare PCI graphics card to test.
1. PC boots up normally (that's before I reformat and reinstall
Windows).
2. Went to reformat and reinstall Windows. That's when problems
occur. During the installing stage, everything goes fine. But... at
the very last stage (where it restarts and auto adjust a screen
resolution for you), the whole screen went blank. zzzzz
Forced reboot the PC. The Windows logo (the one with the green
moving bar) appear and disappear for less than one second, then
blank.
3. Boot into Safe Mode. All goes well. It loads up fine. Seems
pretty much like drivers issue, but I think may not be.
Talking about it... I realized that one setting in BIOS can
effectively kill everything (that means whole screen blackout).
In the Advanced settings, there's a setting called INIT setting.
The reason why the monitor could show that it's using Elsa Gladic
card is because of that. When the PC performs POST, it looks up
that setting first, show it on screen, then continue. That means
POST didn't FAIL at all. If POST fails, it will give out a long
beep, meaning that graphics card isn't detected. The fact that it
does detect and blacks out after that stage soon after wards is way
beyond me.
After getting a PCI card, I changed the setting to PCI. By
right, it should produce the same effect as before... but the
monitor LED light is orange in colour.
Forced restart PC again and change the setting back to AGP.
Since system can't find AGP card... INIT was skipped. Doing so
would produce the effects of Number 2.
And no... the INIT setting can't be turned off.
