Computer turns on for a second only and then loops.

[ARK]

Desktop PC (Compaq Presario S6000NX) turns on for a split second (lights, fans spin, etc.) but then shuts off right after, and then turns back on, shuts off, etc. in a continuous loop. Before this, the PC was working just fine, I take the case off and notice the Floppy Drive is not connected to the power supply (only the cable was connected to the motherboard, I was getting a Floppy Drive error during POST so I decided to have a look inside) so I connect the power cable and attempt to turn the PC back on and I get this looping problem. I disconnected the power from the drive but I'm still left with this problem.

Either your motherboard or power supply needs replacement. Try swapping out the power supply and see if that fixes it. Any local computer shop should be able to sell you a compatible one.

Thanks for the reply. Yup turns out it was a problem with the power supply, PC works now
