Hello,

I was searching google and ran into a post that is exactly the same issue I am having.
When I first boot my Pc in the morning it will lockup requiring me to do a hard shutdown but after I do that it does not freeze again.
It only freezes when I first boot into Windows Vista 64... well about 5 minutes after being in windows from a cold boot it freezes
Looked into updates logs and nothing there that points to my ongoing issue.
I do see others with this issue does anyone know the cause of this?
It appears to be a new issue that is going around. I did upgrade recently ran memtest and heat checks everything is fine even uninstalled my AV to make sure it still does the morning lockup.
Anyone that may know please let me know what you have found or what was done to resolve this issue.
Normally if a hardware/software issue it will lock randomly off and on but this only locks when starting up froma cold boot.

Vista 64 /SP1
AMD PhenomII 260
Biostar M2/AM2+ 8200
Kingston DDR II at 1066
EVGA Geforce 260 Superclocked
700 Watt PSU Dedicated to mainboard/CPU/HDDS/DVD drives
300 Watt PSU Dedicated to single card VGA
3-WD 250GB SATA HDD

Cold boot issues are typically caused by either a power supply or a device not powering up properly, probably the hard drive. All a warm boot is effectively a restart without the power demands needed to start spinning the drives. It's this demand that can cause issues on a cold boot.

*edit* Why are you running two separate power supplies? I don't think that's a very good idea.

The VGA PSU is dedicated for SLI it's a ThermalTake VGA PSU.
I did not rig a second PSU.
Thought about it being a bad PSU but all Voltages look good and it only does it 1x and that is in the morning if I shut it down after that on the same day then restart the PC it does not lockup.
I understand that on cold boot it does a self power check hardware check and a lowlevel command to kick start the cpu.
I have heard others with this same issue as of lately including one of my friends and also found other posts but with no fix for the issue.

PC was locking up on boot then after awhile it started to lockup even during web surfing.
After installing Hotfix for Windows KB942288 the locking up has stopped.
This update is Windows Installer 4.5 strange
It makes no sense to me that this has resolved my lockups but since this update I have not locked up once.
