Hi All,
After a little searching I came up pretty much empty handed so I'll describe the problem.
My beloved AI7 won't boot. It has been pretty faithful over the last year or so--except for loosing a PS a couple of months ago. Replaced it with a good Antec and it hummed on.
Yesterday I tried to boot the computer, things started turning and working (CPU/Northbridge and other fans function, HD motor starts, and the digital display goes through several posts (about a dozen) and always stops at code "AF". There are 2 little LED's found on the board and one stays green (power?) and the second stops at red. No hardware changes have recently been made, nor was the computer moved from its "nest." There have been no cooling issues nor any other hint of problems EXCEPT over the course of the last 2 weeks the screen colors on the monitor appeared faded for awhile upon initial startup.
Symptoms include a long, maybe 2 second beep followed by maybe a second or 2 of silence then the 2 second beep again-over and over. Of course there is the "AF" code already mentioned and the beeps occure after the "AF" has been posted.. Nothing comes up on the monitor (except the message that it has saying the computer isn't hooked up, or what ever.) Funny but the colors of the message are great--not washed out like those that must have been coming from the video card.
The computer does not post far enough to get into the bios screen--remember nothing is being sent to the monitor.
So far I have cleared the bios and tried to find the meaning of code "AF" with no such luck. NO hardware modifications have been done for at least a year--that was when I added the Zalman CPU fan.
The rest of the computer is as follows. 3.0 Northwood that was overclocked to 3.55 at low voltage (1.6) with no issues, 4 memory sticks running in dual channel mode, VisionTec 4200 Video Card, 550w Antec PS.
So where should I start and what should I look for????
I am not exactly a newbie and I know how to use a voltmeter and such. I just need to know what to look for. Your help is appreciated!
Anyone see this before on an established system? Could it be the video card finally gave up the ghost and be causing the computer not to boot? What code would it have given?
Thanks in advance for you help!
