Title says it all!! My friends PC config is : AMD 3000+ 939 pin, MSI RS 480M2IL , 1 GB RAM, GeForce6600 GT, 120 GB Seagate Barracudda (IDE) (as Pri Master). My HDD is Seagate 80 GB Baracudda. As soon as I attach my HDD to My Friends PC's Primary Slave Ide Cable, It doesn't POST (or boot)!!! even without the ide cable, only attaching the power supply cable gives the same prob. No POST! I hv tried exchanging the power cables, ide ports (pri master, slave , 2ndary pri,slave) etc. No Luck. Help me ?
