I just changed my 550W Colorsit PSU for the Corsair 550W VX instead. This is the first time i have done anything like this.
After taking all the connectors out and removing the Colorsit PSU i went to put the new connections in place.
I put the 24 pin connector into the motherboard and the 4 pin connector into the motherboard also. I then put the power cable into the disc drive, i put a SATA cable with an adaptor on the end into my Diamondback22 HDD drive and then the power cable into that adaptor. I also added a power cable to the adaptors which control the fans.
Now when i go to turn it on it makes the sounds like it is working but nothing is coming up on the monitor, it just says "no analogue signak". I put the VGA cable into my LCD TV to double checka and the same thing.
Ok i took your advice and checked the card and RAM. I wiggles each one and they seemed to be firm, they barely even moved. Then i tried to turn it on again and it booted up fine, signal and everything.
Thanks guys, they seemed so stiff i can't believe that was the problem but it seemed to be the one.
Can i ask one more question as i am about to put my new graphics card in.
I am about to put an Nvidia GTX 260 in for the 8500GT, do you know if i need to manually uninstall the drivers for it before i put in the GTX or will that happen automatically when i put the GTX cd in?
