Reboot and count the beeps carefully. Typical beep codes on the 4700 are in groups of 3, eg 1-2-3. There are only three codes I see which add up to 6:
1-1-4 ROM BIOS checksum failure
1-2-3 DMA page register read/write failure
3-1-2 Master DMA register failure
What color are the 4 diagnostic LEDs on rear of the tower? If not all green, look up the error code here.
You could try resetting BIOS by clearing NVRAM. Unplug the PC from the wall and press/hold power button on the tower for ~15 sec. Open the case and remove the battery from the motherboard. Press/hold the power button again for at least 30 sec. Reinstall the battery, right-side-up! Close the case and see if it boots correctly now.
Could be a bum video card or a bum motherboard. :emotion-9:
The funny thing is that the PCI Express slot has never been used. I looked up the light code on the link you provided. It stated "Memory modules are detected, but a memory failure has occurred." So I removed the memory sticks and replaced them 1 at a time. I got a picture again. The new light code the told me that another hardware failure has occored and i received the original "Alert: PCI Express Card Is Running In x1 Mode".
So i took your advice and temoved the battery and "drained" all power from the machine. I then replaced the battery, booted up into setup, set the time, and now the mach9ine works great again. A friend told me the the BIOS was possibly "scrambled". Thank you for your help!
If the problem recurs, it's possible the motherboard battery is weak, especially if it's more than ~2-3 years old. In that case, it's $2-$3 for the coin cell battery at places like Walmart, Target, drug stores, etc.

And you're sure the card is seated properly?

Glad to hear it's working again. :emotion-2:
