Hi, all.
The Problem:
Recently, my machine decided to stop showing any video during boot. All 3 displays are blank (BIOS memory count, text-mode and low-res graphical portion of the Windows boot) until Windows initializes multi-monitor mode.
I'm pretty sure that I didn't change anything to make this happen. I rarely reboot this machine (like once/month or less). There was probably some software update which required a reboot, at which time I noticed that video was missing. I may have taken the reboot as an opportunity to check or change some BIOS settings, but I don't remember (this started a month or two ago, I was just reminded of it because I rebooted today).
This is frustrating, since I can't see the BIOS setup to be able to experiment with different settings.
What I've done to troubleshoot:
When I first noticed the problem, I went back into BIO setup (blind), and changed the AGP timing. This fixed the problem at the next reboot, and I was able to see BIOS setup. Of course, I had actually changed the IDE setting for drive 3 from CDROM to "not installed"
- but it still fixed the problem.
-- until I rebooted. At that point, every second boot showed proper video, and the alternate boots showed nothing (the monitor doesn't even come out of power save mode).
I now get nothing on any boot: soft boot, reset button, power down, full power down (unplug ATX supply, press power switch to drain caps, wait, plug in, turn on)
I did fiddle with BIOS settings a bit (AGP/PCI timing, memory timing, etc.), but nothing helped. I haven't tinkered with BIOS settings now that no boot gives me anything to look at.
I'm hesitant to flash the card BIOS, since I won't be able to see anything.
I have tried booting with Memtest86, and it runs, but doesn't show any video.
The Machine:
AOpen AK73ProA (VIA KT133A chipset)
1.5G PC133 SDRAM (3x512M DIMM)
Creative Labs SBLive Value
Creative Labs 12x CDRW drive
IBM 120G IDE HD
D-Link DFE530TX+ network card
Windows 2000 Pro
I haven't run the "System Logo Fix", and I do have a boot logo enabled. It seemed unlikely that this is the problem, since this exact configuration used to work (again, I'm pretty sure that a reboot was only forced by some stupid DLL problem with PCAnywhere or the like).
Any suggestions?
Thanks
