I believe there can be problems die to following:

1] Problem from main power point in your house/particular outlet where you are conneting... (Your electrician can check this with a device called "Multimeter")
2] Problem in the wire that you are connecting from PC-to-TV
3] PSU not outputting enough juice to your system (if you replaced your PSU with a brand new unit you can rule this out)
