Having a nightmare with new rig - possibly psu related?

[slinger]

To cut a long story short on Monday I bought a new AMD Phenom II X4 940 Black Edition cpu and a Gigabyte MA790X-UD4 motherboard. Came to install everything and my usb mouse briefly powers up then turns off and the usb keyboard doesnt work at all. Used a ps2 adaptor which worked very briefly so borrowed a ps2 keyboard and that worked.... agin briefly until pressing any key in the bios did strange things like bring up "quit without saving".

Took that motherboard back today and got it swapped and have put everything together again but again usb keyboard and mouse wont work, BUT with the ps2 adaptor on the keyboard it works fine, the mouse doesnt work at all though. Managed to start installing Vista using the keyboard and its very very slow to install. When it gets to the "completing installation" screen it throws up the following Blue screen:




It seems to me that maybe my psu isnt up to the job (PC Power and Cooling 510w) but is there much more of a demand for power on this new system than compared to my X2 6000 and Abit motherboard? I cant afford, and dont want to buy another psu only for it to be something else like the memory I have isnt compatible with this motherboard [no]

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

Try running a memory test you may need to manually adjust some timings and voltages on the Ram to get it stable with your new mobo. I believe Vista has a memory test program built into the installer (been a while since I've had to reinstall a vista OS) if not use memtest86.

Did u plug in usb correctly, i mean on the motherboard have to plugin for your case usb, if your case has any extra usb.

Yes have checked, double checked and tripple checked everything I can think of. I even tried it without the front header plugged in.

I think you have a bad CPU. I used to recieve that error, right as windows was saying "comleting installation" and every time, it was related to a dying cpu.

Have you checked if you seated the heatsink properly for your CPU? It sounds like since it's running slow and being flakey that the CPU may be throttling severely because of overheating, ie, improperly/poorly mounted 'sink.

Just a thought.

Also note that quadcores do indeed use alot more power than dual cores. My Q6600 has someting like a 120W TDP I think? Whereas my old E6600 was like 65W...dunno about the AMD quads.

Last night I did the following:-

Firstly flashed the bios to the latest F2a using a usb drive which worked fine

still no luck so I did the following hardware changes:

2 x graphics cards - GTX260 and a geforce 7300
2 x memory - Geil PC6400 & Kingston KVR667
2 x CPU - Phenom II X4 940BE & X2 6000
3 x DVD Drives - Optiarc SATA, Sony IDE & brand new LG IDE
2 x hard drives - Seagate 250gb SATA
3 x keyboards - Logitech Media 600 USB (didnt work), generic PS2 & Logitech Elite with PS2 adaptor (both worked fine)
3 x mice - 2 x Logitech MX518 & 1 x Microsoft Explorer (none worked)

so, the only thing left is my psu which is obviously the problem. It took a long time getting here but at least I know (and hope) the £60 I spent today on one might not have been wasted.

Here's hoping............... I have plenty of beer in the fridge in case its not worked

Sounds like this bug:

Could be related to the 4GB ram problem with installing vista. Have you tried with a single stick, I see you swapped some out? Last resort would be to slipstream a copy of SP1 in to the vista install disk.

It was the power supply, put the new one in tonight and everything is hunky dorey! [thumbup]
