I've recently installed a new video card (XFX Geforce 5700) into my system, along with a new power supply (Antec TrueBlue 480W), at almost exactly the same time.
The new setup started out okay with no problems for the first few days, but now I am getting random system freezes, with crazy colours on the screen, which is only fixable by a reboot. Usually the problem will recurr immediately on reboot, until I've left the system powered down for about half an hour, after which it's okay again. This started happening when I started playing games (Soldier of Fortune II), but it has also happened just when I was burning a DVD.
I've looked in the event log, and in all but one instance the shutdown has been preceeded by an Event 111, with the description "Silent Running: HW clock slowdown due to missing Auxillary Power."
The video card has its own Molex connection. I'm guessing that this error is suggesting that the molex is not connected, but it is.
Can anyone tell me if this is likely to be caused by a faulty GPU, a faulty PSU which is failing to supply enough power, or something else?? I can't find much info on the error message via Google etc. Also I'm confused about the one occasion on which there was no error message.
Bios and all the drivers are bang up to date. Unfortunately I don't have another video card or PSU with which to test this out. Full system specs are below. I know there are a fair number of peripherals attached, but I would have thought 480W true power would be ample to power this setup?
Thanks very much!
