My System:

* AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor Model ADX6000CZBOX
* ASUS M2N-SLI Deluxe AM2 NVIDIA nForce 570 SLI MCP ATX AMD Motherboard
* PSU: Antec Smartpower 500W
* 4 sticks: CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4
* Western Digital Caviar SE16 WD2500KS 250GB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive
* Windows 7 x64 RTM

If I go into sleep or hibernate mode, the only way to power back on is to unplug/plug in the unit (I just toggle the switch on the PSU).

I had a Corsair 750W PSU in before and this did not happen with Windows 7 32-bit. When I changed the PSU, I installed Windows 7 64-bit. Now the problem happens.

In the bios, the standby modes are both S1 and S3.

Is the problem too little power (wattage), the bios standby mode, or Windows 32 vs 64 bit?

I haven't messed around with Windows 7, so I don't know the default settings. That said, how are you attempting to "wake" the computer up?

If by keyboard for example, have you checked to see if it's a device that is allowed to wake the computer (control panel - keyboard properties - hardware - power management)?

I would also check any Energy Star settings (specifically under the advanced settings).

I've tried the keyboard, mouse, and power button. None work.

In the bios, I have wake on: keyboard, pci, lan, modem, everything!

In windows, under the properties for the devices listed above, I've ensured that each can "wake the computer from sleep".

I'm beginning to think it is the power supply and will try swaping it out with one that has more juice.

I bet it's a bios issue



What makes you say that, considering the two hardware changes: PSU and Vid Card?
