Maxtor ATA133 80gig
Asys 222L Case
Asys 450 watt PS


now, my problem is, i have everything installed, tested mobo/cpu/ram and it booted fine and temps holded as well as voltages from the PS

i connected my molex connectors to my cd-rom drives and rebooted and it posted good

finally connected the HD and the when i hit the power button the system just blips on for a split second then turns off

i tested the HD in another system and it loaded fine on it as a secondary drive.

what could be my problem??????

It could pretty easily be that the generic PSU you are using can't hadle the load..try disconnecting the CD-ROM and see if it will boot with the hard drive connected.

i've gotten it to load with just the cd roms but even with no other molex connections it will NEVER load teh HD

check all your connections and jumper settings.

Make sure you have the correct end of the data cable hooked to the drive.
