Occasional Blue Screen

Hello,

Im a brand new member, so thanks for any help in advance. This machine is my primary windows media center. It has an occasional blue screen. but the real problem is after the blue screen It reboots but cannot find the boot drive until I ctrl/alt/del or power off and back on again and then it is fine. This has made consistent recording sometimes difficult :) I have lived with it for quite a while but now I have a little more time to trouble shoot. Thanks for your help and if you need more info please let me know

I hate to bump a thread... is there more info that I can provide that will help with this issue?

Thanks for the help
