Standby wont work after new motherboard

[OnionMan]

I put in a new motherboard and a new powersupply. Now the system wont standby. Arrrrg! The monitor turns of but the fans stay on. Usually everything comes back on right away. I tried reformatting the hard drive to no avial.

Motherboard Gigabyte 865PE GT
Windows XP Pro Service Pack 2 (maybe it was SP1 before when standby did work)
ADSL modem, no LAN or anything like that

Im taking a stab in the dark here and guessing a driver is messing up my standby because I did install a bunch of new drivers when i reinstalled windows. I want to try uninstalling some drivers i dont know if ill mess up my system doing that. Which drivers should i try? Or am i on the wrong track here? ANy ideas are apreciated. Cheers.

usually BIOS plays vital role in Standdby.

check ur manufacturer that if ther is mentioned that in SP2, if stand-by is failing, then u might need to upjgrade the BIOS.

check that out.

Problem Solved!

Your right about BIOS. I had played with the settings in BIOS Power Mangament before to no avial. This time i changed ACPI Suspend Type from S1 or S3 .

That worked, almost. I could finally get into stangby, but not out... so I had to enable the Power On By Mouse thing in BIOS. Now it works.
