My friend recently put together his new rig. This is the video card:
XFX Nvidia 6600GT / AGP 8x
On boot up, the screen where the AGP device is detected and the video card specs are displayed in plain text, as well as the motherboard boot-up sequence (pre-WindowsXP starting screen) appear to flicker. The text seems to have horizontal lines running through it, flickering left and right. However, once WindowsXP boots up, the images are crystal clear, no flicker whatsoever. Looks fine in games, Windows GUI, etc. No, the video card is not overheating. It is connected to the PSU via its own 12V cable, with nothing else on that cable. The PSU is an Antec 400W with 28A on the 12V rail. The only thing out of the ordinary is the analog monitor being attached through a DVI > Analog converter. But, like I said, the images are crystal clear with no flicker.
The question is: is there need for concern? Does this flicker mean something bad is going to happen / is happening? Is it a motherboard problem?
Here are the other system specs:
3.0GHz P4 Northwood
Abit IC7-G mobo
1GB Kingston ValueRAM
[Edit]: The monitor is a Samsung SyncMaster 150mp with analog input.
