Help!

Hi all

I have built an htpc using a Aria case with built in 300w PSU and using a AMD 300 CPU.

For some reason the video 'wobbles' if I install Vista so I have used XP to check the machine and it runs fine.

I am considering installing a separate video card, but the mobo only has a PCI-E slot and the PSU does not have PCI-E connectors!

So the questions are:

Is the PSU powerfull enough to power a dedicated graphics card?

Can you get a PCI-E card that does not need a separate power input?

Any thoughts on the vista wobble?


Any thoughs on this would be gratly appreciated!

Hi.

What do you mean by the video wobbles?
Most video cards these days come with PCI-E - Molex connector for PSU's to power them when they dont have PCI-E connectors, but it depends what GPU you want, any modern GPU is going to be bottlenecked quite a lot by your CPU and I'm guessing the PSU is a generic 300W PSU, it wants replacing if you are to get any decent card but then again it depends what you do, do you game or just want one for office work?

possibly you've not set the correct hz on the display?

Hi - thanks for the responses!

I have just done a clean install of windows media centre and the problem is still there - so it appears to be somehow linked to newer versions of windows!

Cant upgrade the PSU as it is case specific - not really bothered about playing latest games as system was bulit primarily as a media centre.

I will try experimenting with the refresh rates - but I dont think that that is the problem.

Any other ideas?

Sorry didn't answer the question re the 'wobbling' it appears as if the start menu - or some other menu flashes on and off the screen - does not seem to matter what resolutions I am running, but as it does not happen using earlier versions of windows I am sure that it is software related.
