Powering off and Drivers problem.

Question

Hi,
I just built my new rig afew days ago and all was well for until this morning. My rig keeps powering off by itself (no bsod or anything even though auto shutdown is disabled) and the power led on the case starts to flash on and off every second also the keyboard seems to still remain active (numerical lock led stays lit but non of the keys respond). The shutdown occur randomly and the only way to power back up is to disconnect the power cord for afew minutes and try again. I will be replacing the cheapo power supply with a Enermax EG465AX-VE in afew day hopefully but before I go out and blow £70 on one could anyone confirm this to be the most likely solution or could I try something else first.
The second problem I have got is that I can't install the Via 4in1 drivers (v4.51) and/or detonator drivers for the MSI FX5600XT card with out getting random lockups/frezzes and some programs failing to install e.g 3dmark2001 hangs half way through installation. I have re-installed Windows and am using the standard MSI drivers that came with the card. I also managed to install and run 3dmark2001 and Prime95 for 12 hours without any problems. But once I installed the Via drivers and/or Detonators /v45.27/v52.14/v56.64... and have AGP mode  8x enabled, I started to get those random lockups again so I uninstalled them.
Any ideas would be greatly appreciated.

Answer 1

Hi,
I have installed the via drivers after uninstalling the MSI detonators then reinstalled detonator v56.72. I can now faithfully reproduce the 'invite loop error everytime I click on the FX5600XT tab in display setting and am getting a 'infinite loop error' 0x0..0EA. I have swapped both sticks of ram around tried one at a time but no joy.
@jacko
I am currently running on one stick , no shutdowns yet but it's still early days.
