I'm running my NF7-S v2 with BIOS 23. I boot from a 160Gb HD using the\nserillel adapter on SATA1. I have a 400w power supply.\n\nOn cold boot, the drive doesn't get detected. I have to leave the machine on\nfor about a minute and then turn it off at the mains and then on again\nbefore it is detected. Just hitting Ctrl + Alt + Del (without powering off\nfrom the mains) doesn't work.\n\nThis problem happens nearly everytime (now that it is winter in the UK) but\nonly occasionally in the summer. Any ideas on this please ?\n\nThanks in advance.
