Air path has not been changed recently neither.
Last week i began dampening my case with gedicoustic (mutemat ?) :
Sides, top panel, and bottom : there is a slight overlap with the edge of the motherboard.
So far, it ran smoothly.
Two days ago, i removed the mobo from its tray to put a layer between the mobo and the tray, in contact.
To achieve that, i had to remove the PSU, and thus also the SI-97.
When remounted, everything was ok, but i have no long stability test to be sure of it. Temps were exactly like before.
But yesterday, I put another layer in the back : it touches the connection ports, the edge of the mounting for the video and the edge of the mobo.
Now the system is no longer stable : i experience screen blank outs and image scrambling. I reopenend the case to check the graphics board : it is correctly seated and secured in the agp slot. It doesn't even move when i push on it.
The ribbon of the monitor is correctly screwed to the pb is not there neither.
FYI, the vga card is not hot : the issue can happen during boot or just after.
It looks like a component is getting too hot on the mobo, or there is a short circuit because of the pressure the layer applied somewhere.
Has someone encountered this kind of disappointment ?
(Maybe i should not have used staples to fix the mutemat on the motherboard
)
