Problems booting after long shut down Tags: Homebuilt Computer Shutdown Systems Last response: January 3, 2011 9:11 PM in Systems Share djnardu January 2, 2011 6:26:57 PM So I have this issue, if my computer is shut down for an extended period of time 1+hours, when I power it on I must turn it off and then on again to post. If I come back from sleep there is no issue it boots right up. If I only have it shut down for a few minutes it boots right up. Anybody have any idea? 90% of the time the computer is in sleep so its not a huge issue but still an annoyance. Any idea what could be doing this? Ive left prime running for about 10 hours no problem and I can restart 5 times without it giving any issue.
