I have a PowerSpec 6342, integrated graphics. If I disconnect the HDD, computer posts. If I connect HDD to mobo using IDE cable with no power, computer POSTS. If I connect HDD to PSU (without connecting IDE cable, computer clicks and immediately shuts off. Tried different HDD, same result. Is it a bad PSU (original) or bad mobo. I also disconnected DVD from PSU and mobo and tried to connect HDD, same result.

Sounds like the power supply is giving you the problem. You can buy a new power supply and try it. If it doesnt work, return the power supply.

Based on the fact that computer posts when HDD is disconnected yet DVD is connected, I would suspect HDD or at least the power cable that it uses. It could well be a weak PSU or broken cable going to HDD, so try the plug that runs DVD on the HDD leaving DVD unplugged. If that works, try it with a different HDD on the first cable HDD was plugged into and I'll bet it boots.

Thanks. I tried that and it did not solve the problem. I also put in a different HDD achieved the same result. I put the "old" HDD in an external enclusure and checked it on another computer. It seems to be fine and I can access the data so I don't think it is the drive.

Thanks for the quick responses. My intuition is that it is a bad PSU as well but wanted some support for the theory. I'll let you know if that is the problem.

UPDATE: Replaced PSU and hard drive operated.
