PC trubbles

I've posted this over on the NAG forum also, but perhaps someone here can help me out.

Sometimes (and increasingly often) my PC doesn't shut down properly. It just hangs on the "Windows is shutting down" screen, and I have to switch it off manually at the PSU. It's also occasionally (and, again, increasingly often) having issues during boot - it's not powering my USB devices properly. My keyboard (Logitech G15) doesn't come on at all, and my Wacom light flashes briefly, but by the time Windows has loaded, it's not actually working.

A single reboot usually solves the problem, but sometimes multiple reboots are required. Although I've not tried this enough times to say with certainty, unplugging the USB devices before booting, and then plugging them back in once Windows has loaded appears to work too, suggesting an initial power consumption issue.

It's the PSU, isn't it?

Ok firstly what is the size of your PSU?? and in Watts :) secondly have you reset your mobo as in pulled all the cables out and pulled the cmos battery out and left it for 5min?

Try another PSU, sounds like your mobo isn't getting enough power. You will be surprised at what power fluctuations cause on PCs.

Maybe enough power, but not quality power.
I had a mate who had similar problems and after testing found his PSU was pushing our 10V on the 12V line and 4V on the 5V line. <--- uber shudder at the damage that can cause...

No, that's more effort than I'm prepared to put in at the moment. It's a 420W PSU, and I'm increasingly convinced it's the culprit here. I'm sure I didn't have this problem before installing a 9800. I guess I really should have a 550W PSU or more. >_>

I wouldn't be surprised, that's why it's my prime suspect. :P I've previously had a very similar problem with another PC, where powering up the PC and monitor on the same PSU simultaneously caused issues. Just wanted some second opinions. Looks like I'm buying a new PSU.

Yeh a 550W would do the trick most definitely :) I also wasnt able to push out enough power when it came to gaming when I had my 450W and that was also when I knew nothing about PC's and worked out to get mah hands on 550W and higher in order to push out what i needed :)

Press F8 during boot up, Choose Last known good settings ?:)

... Doesn't sound like an OS thing, so that isn't likely to do anything.

Try a different PSU - and if that doesn't help, play around with using different RAM chips to narrow down the problem.

Is it a generic psu? i'm not convinced that the psu is the issue tbh. But let's see what happens.

Nah, I doubt that the RAM is at fault here.

It's a Thermaltake PSU. So not a generic, but nothing super fancy either.
