My ASRock - K7VM3 motherboard worked fine for about a couple of years. Now if it remains off for a couple of hours, it takes a long time to post. If there is a CD r/w drive it will not post at all. Also, if CD is placed in CD r/w drive after boot, computer will shut off and keep restarting. I read somewhere that connecting CD r/w drive to ide1 and hard-drive to ide2 might help. It did not. I put in a new IDE cable and a different power connection to CD r/w. It did not work. I don’t think Samsung CD R/W is broke. I am still troubleshooting. However, I will appreciate any tips to help.
