Built a computer from Frys components used old HDD now will not get past the waiting to login logo and smell ozone. When installing the drivers from the CD of MB it took along time to load 30 minutes for 3 mb. The systems is a Gigabyte GA-MA69GM-S2H Socket AM2 Motherboard/AMD AM2 CPU/Nvidia 8600GT video card/2 Gigs DDR2 memory/Smiledon Tower with 500 watt power supply. The HDD is old Western Digital 120 Gig IDE and 60 gig. the OS is on the 120 gig HDD. Why is it locking up and make a large bad smell of burning electronics????
