I'm pulling my hair out with my Abit IP35 system. It's worked perfectly since I bought it, but these new issues have arisen recently. It appeared to happen at the same time as upgrading from one of the Windows 7 betas to the final RTM Professional, but obviously that might be a coincidence.
The hardware is:
Abit IP35 XE Pro
Intel E8200
2x2gb Crucial Ballistix PC2-6400
Radeon HD4850 512mb
Crucial CT64M225 SSD
WD WD6400AAKS HDD
Akasa 80plus 500W PSU
I have always used S3 sleep in the past, which worked fine, but since the new install, this hasn't seemed to work at all. The machine always seems to go into hibernation (whatever the power saving settings) and then needs to reboot from bios to recover (ie. it says 'resuming windows' when it starts).
I've also noticed some unusual activity in the red power and bootup leds. When I power the machine down, the red led (3vsb) flashes for some time. While it's flashing, the machine cannot be booted up again. After a minute or so, the flashing slows until eventually the red light is on constantly. At this point the bootup led reads "02". The machine still can't be booted up, and when I try, the boot led reads " 2" (thats nothing in the first figure). Eventually, after another couple of minutes, the machine will boot up again as normal. How screwy is that?!
When the machine is put to sleep, the behaviour on the leds and the delay on restarting is actually the same... In fact, if I disable Hybrid sleep, when I try to reboot the bootup led changes to " .F" and doesn't boot, and when it finally does, the machine reports a failure to shut down properly last time, and reboots from the start...
I've cleared the CMOS and started again, but have made no progress. Any suggestions?
