Ok, heres the (rather baffling) deal: You can suspend XP Professional on my machine You can resume XP on my machine You can press suspend for a second time, and then it locks up - just sits there on the "Preparing to enter suspend" screen. I've tried just about everything I can think of. I've got the latest BIOS revision for my board. I've downloaded every singel windows update (no small task with a 56k modem). I've tried fiddling with the AMP/ACPI options in the BIOS and in windows, and this happens regardless of what suspend mode I use (either suspend to ram or soft off). I've tried removing cards from the machine. Nothing will fix this problem! If anyone can come up with a suggestion, I'd be grateful... My system: ECS K7VZA Version 3 (running BIOS revision 3.4) VIA® VT8363/8363A or VT82C686A/B Chipset (manual is not clear on this) AMD T-Bird 1Ghz not o/c'd, cooling fan rated up to 1.4Ghz 384Mb CAS2 PC100 SDRAM not o/c'd MSI brand nVidia GeForce3 Ti200 64Mb not o/c'd Creative SBLive 5.1 digital Hauppage TV/Radio card 20Gb Seagate HD (primary master) 10Gb Seagate HD (primary slave) 12x Creative DVD (secondary master) 24/10/40 LiteOn CDRW (secondary slave) Additional fan at rear of system Operating temps: CPU: ~40C Case: ~30C Nothing is overheating, nothing is overclocked. The system is rock solid - for example it has been up for 12 days now, running all sorts of stuff (games, mp3 rippers, and so on...). It will hibernate, it will restart, it will shut down, it will log off. It just wont suspend more than once.
