Your issue sounds as though it is the power supply that is in need of replacement.
If there is a steady red light on then the PC unit is not getting it -12/+12/-5/+5 voltage at the connectors also you may have inadvertently switched the cable connections that is pin 1 of the cables is not getting the voltage it needs to the device.
The red line on the cable or the (+) is the supply pin to that device.
1. check the power supply and all the connectors.
2. clean all dust from the inside of the the connector and around the CPU
3.check the CMOS battery (looks like a new quarter) should show 3.7 volts with a volt meter. If readings are below this you need replacement.
I hope this helps. Have a great day!

Power went out i tryed to turn the xbox360 back on it didnt work


Take the Hard drive off, unplug the power wire from the wall, and plug it in to a different outlet, make sure the RCA (red,white,yellow)cables are still connected from Xbox to TV(or this will give red lights when turned on) and with that done, turn the unit on. Are the lights gone?

Prolems with the power.


Try leaving it off and unplugged for a while then hold power button while pluging back in to reset. Most brands of tv's flash to display trouble code.

Turn the computer on, steady red light and beeping.


Have check for the pins connections who makes it to be master or slave? Have check how you plugged yours cables at HDD? Know that , the cables are plugged as following:
After to put in the power cable, the data cable must be put in in the way that the Red line must be in the direction of power cable. Check all this , if your HDD was good before , i believe that it will work.
Thanks , good luck!!
