Yup, it is in the RUN position already but still cant detect any USB blaster.

Actually, I don't think the RUN switch should matter. In either case a USB-Blaster should be detected, but in RUN position it should operate in JTAG mode, and in PROG operate in AS mode.
You pretty much need to probe around the USB-Blaster circuit and determine what is wrong. You indicated your system worked with another DE2, so compare the signals on both boards and see what you find different.
Use the standard debug sequence;
1. Check power supplies
2. Check clocks
3. Check resets
Then for your DE2 debugging, look at the FTDI FT245 signals.
