Guys please help me...i was trying to install win 7 64 bit OS on my system which previously had 32 bit win 7 ultimate installed...Yes , my comp is compatible with 64 bit OS.. But after a short while during installation...the stage after windows is copying files...window....the screen turn off ...the keyboard and mouse are also powered off....all the connected devices are not receiving any signal from the CPU and also the PSU fan is not working...whatever i do....remove RAM and put it back..the CPU power button turns on...but nothing is working...! Also i was trying to install win 7 from a bootable pendrive .But now no component in the CPU seems to work...please help ...thanks....!!

Where did you get your copy of Windows? Because some contain viruses in them that might explain your situation. Try to boot from a bootable Cd that came with your antivirus.

Have you plugged it in? Is the PSU's voltage switch set to its right voltage? Have you tried to test your PSU using a paperclip? Are all the cables plugged in?

it is not good to be removing hardware while the system is powered on, and powered on as in turned on, not just the power plugged in and sitting off
