I have an Athlon 2200 based pc on an MSI 6590 board with 1GB ram. Working fine for a year or so but now it has started to lock up after 10-20 minutes, no matter what is happening with the cpu (could be idle or intensive). The keyboard and mouse don't respond and the screen appears as it is at lock up. Only way out is to press reset. Does anyone think this is a memory problem? The installed memory is 1x512MB + 2x256MB DDR modules, but they are generic from PCWorld. Do you think I should change these for something from Crucial or similar? Any ideas please?
Current memory modules are all 333 MHz, ie PC2700. One thing I did though - I had in slots 0,1 & 2 originally, modules 256, 256 and 512. These locked up. Then tried swapping the 512 and 256 modules so slots 0,1,2 now have 512,256,256. However on reboot the 512 is no longer recognised. System still locks up though.
I think that next I will try and run with just one module in situ and rotate these in turn. If I get a lock up on one only then that's faulty. Don't know off-hand which specific Athlon 2200+ cpu I have (pc is at home), but should I be using 266 MHz memory to match the cpu bus speed, or does it not matter?
