Untold woe with new upgrade

[slinger]

To cut a long story short on Monday I collected a new AMD Phenom II X4 940 Black Edition cpu and a Gigabyte MA790X-UD4 motherboard. I came to install everything and my usb mouse briefly powered up then turned off and the usb keyboard didnt work at all. ISo I tried using the ps2 adaptor which came with the keyboard which worked albeit for a matter of seconds, so I borrowed a ps2 keyboard and that worked.... again very briefly until pressing any key in the bios did strange things like pressing the up arrow brought up "quit without saving"

I returned that motherboard today and got it swapped and have put everything together again but again the usb keyboard and mouse wont work, BUT with the ps2 adaptor on the keyboard it works fine this time, the mouse doesnt work at all though. I managed to start installing Vista using the keyboard and it is very very slow to install. Then when it gets to the "completing installation" screen it throws up the following Blue screen:



Can any of your tech guys shed any light on this without me having to return it again? I cant see it being the cpu thats at fault, maybe a dodgy batch of motherboards? I have a PC Power and Cooling 510w psu and its coped fine with my past setup (X2 6000 and Abit KN9 mobo, everything else as it is now) so I cant see it being a psu issue? My system specs are in my profile and signature.

thanks.

p.s. click on the pic and it should go full size

Is that a Vista RTM disc? If it is, I would try again with either a Vista SP1 or SP2 integrated disc.

RTM? Its Vista Ultimate 64 that i bought from Scan in January 2007.

do you mean usb keyboard+mouse dont work at all?
if so then plug in the ps2 keyboard, boot up enter bios then check through and if present enable usb keyboard and mouse options in bios to allow use.

yes and I've tried that but still no joy.

Have you access to another pc where you may try the kybd+mouse? maybe second pc, work, friends place? If they don't work in dissimilar board then probably they have some fault. I'm assuming here they were new items for this build? Or were they your old ones and worked fine before?

[slinger]

No they're all existing and are working fine, Im using them now after putting my X2 6000 and motherboard back in, everything else is the same, all I have changed is the mobo and cpu. Have used eXtreme Power Supply Calculator Lite v2.5 to work out and based on worse case scenario of using all 3 of my hard drives is states recommended psu of 389w.

I might be wrong here but I thought the Phenom 2's used less power?

Depending on the core a X2 6000 pulls 89 to 125w a 940 pulls 125w.

What version bios is the board running btw, as the 940 was only supported in revisions F2 and upwards, what the board ships with does not fully support the 940.

Not saying this is related to your problem just a possability.

I've no idea to be honest but it recognises the cpu.

Would this be a capable psu do you think? http://www.scan.co.uk/Products/850W-...ency-Black-PSU

Not a clue then tbh, recently built my cousins PC using the MA790x UD4P board in the same range and its been ok. Really doesn't like his Belkin USB wireless dongle though and took a few driver versions to get it working without causing bluescreens and shutdown lockups, everything else hes connected via USB has been ok though.

*Edit* Personally don't think its the PSU tbh, seems like a issue with the board more then anything.

[slinger]

What psu is he using?

[Jasp]

Built his using a corsair 650TX as i heard very good things about them.
