I recently built a new PC using the cast-off parts from my old Dell 4600C desktop, and ever since then I've been unable to use S3 standby properly. When I try to wake up the machine, I can hear what I think is the CPU fan start spinning, but no image appears on the screen. Invariably, I have to unplug the computer from the mains and reboot. I'm using a Foxconn socket 478 mobo with my old Celeron D 2.4 ghz. processor, an 80gb. hard-drive and 1gb. of ddr333 memory, also salvaged from the Dell. Any ideas? Thanks!
