First time posting and I am at my wit's end. I pride myself in my knowledge of hardware and software, but I can not figure this one out. I recently purchased a Hauppage 2250 TV tuner card and installed it in my computer. At near the same time, I installed a RAID card to bring my two 250gb drives into a raid 0. After this, my windows 7 x64 Ultimate machine started failing to sleep properly. It would turn off the monitor, keyboard, and mouse, but not the tower with the fans and HDDs. Then, it would not be recoverable. I would try to wake, but would have to power cycle TWICE to get it to then "delete restoration data" and boot fresh. I can read nothing into the Event Log that would tell me. I have turned off hybrid sleep and this did not help. Also if I sleep by way of pushing the button, it will sleep properly. If I just let it wait out (as in after a recording) it will get into this unrecoverable state and miss any other recordings. I have searched and searched and have not found a solution. Anyone here brighter than me that can give me a hand?
