I recently had some memory problems on my pc. I had a 512 mb RAM, PC 3200 400 mhz DDR, 184 pin module. I ran memtest and it failed the tests so i went out and purchased 2 Kingston KVR400AK2, 512 mg RAM, PC 3200 400mhz DDR, 184 pin. The motherbaord is an ASUS A7N8X Deluxe. I formatted the hard drive and i am trying to install a fresh copy of windows but the system seems rather sluggish. The HD is already formatted. I read the ASUS manual and i placed the memory in slots 1 and 3. Any ideas?
