Change of CPU

One more trip to S. P. Road, this time to Rajshri Computers Inc. for:

Asus M2N-MX Motherborad - Rs. 3650 + 4%
Athlon 64 X2 Dual Core 3600+ Microprocessor - Rs. 4350 + 4%
Transcend JetRam 533 Mhz 1GB (240 pin) DDR2 SDRAM - Rs. 3400 + 4%
Frontech ATX Cabinet with SMPS - Rs. 1400 + 4%
for a total of 13,312/-

Update: I didn't test it then and it didn't work when I got it back home. The fan was rotating for about two seconds and then stopping each time I pressed the Power button.
One more trip to S. P. Road. The heatsink-fan hadn't been inserted correctly. When he corrected that, he found no display still - that was because the RAM module was faulty (shared display RAM, remember); a replaced RAM chip and finally something on the screen.

It's working quite fine now.
