recently i've been getting a problem when i try to boot up. The POST fails and it kills the computer. There's a low whirring noise (one of the fans running slower which makes me think power), and a long ass beep, then it shuts down. I have Award Bios v6, the site says a long beep is memory, but i haven't touched the memory in months, it's been working the whole time, and i'm running fine right now, even after a reboot (needed to see what bios i had). The system properties find all the ram...i don't know whats up. My first thought was, maybe it's too cold or something, that would explain a lack of power and the erratic occurence of the problem. For example it happened 2 times last week in the morning, and today it took 2 hours before the mother would start up. But the manual online says that beep is for memory, which is highly doubtful cause i know for a fact it's seated just fine, and it's only a few months old so it's fine. But, when i finally got it to boot this morning BIOS said it was room temperature so it couldn't have been too cold. I haven't had any problems while the computer is running. I can't figure out what's going on, any suggestions?
