I could possibly buy another psu tomorrow....how about these: www.pbtechnz.com www.promax.co.nz Obviously it's all time &money though. Checked the 4pin to board connector 12.24v Other on the 24pin setup 12.24v & 12.01v That 24pin setup is actually a 20pin plus a 4pin. That looks to be normal from what I can see? If I leave the board running for a few minutes, the heatsinks get warm to touch. Some onboard graphics will only work with RAM plugged into slot 1 for example. Have tried all the slots with the corsair no beeps. No ram at all: no beeps as well. Will test ram in another PC shortly and post back IF that fails. Will test the speaker too. The hard disk is a 500gb and it's as new with nothing on it, not formatted yet. That shouldn't matter for this lack of beep problem?? Manual says corsair cm2x2048-6400c5 is supported with all the 3 options listed. How would I determine what bios the board currently has? I see most of the cpu's require the v0217 or newer but how can I physically find out which this board has? Incidentally is vga or hdmi monitor/socket type the better to go for while just trying to get this board to wake up? Thanks.	Tbird650 (6754)
752216	2009-02-28 21:13:00	Remove all the memory - fire up the board it should beep like crazy indicating no RAM. With no memory installed there's not a peep out of it, as before. I'll see if I can test the speaker.	Tbird650 (6754)
752217	2009-02-28 21:15:00	Yer I do, thats why I said true. And Tbirds's link didnt work. Which is why I gave a link that works Sorry, Obviously I'm the one who needs to read posts properly! :o Honestly, though, I think the PSU is probably OK. Try to borrow a better one rather than buy	Agent_24 (57)
752218	2009-02-28 21:41:00	Just adding to / agreeing with the others - I doubt the PSU is the problem . As mentioned in the original Post tried 450w psu on another system assuming it worked OK on another system, then you can try any PSU as long as it has the connections for the components, High power is not required for booting into the BIOS etc . What I would do in the workshop, and it is a pain in the butt - But I would change 1 component at a time to a known working board, make sure that component works OK . If the component works in another board, and in the end its only the board left - theres the problem . You can of course do it in reverse - put known working components in the New board - if it still fails problem pin pointed . I know not every one has spare components to play around with, but unless it can be pin pointed as to where the problem is you can be going round in circles for hours going crazy going nowhere . If you are able to do the above - you have basically done what the shop would do first to test the components .	wainuitech (129)
752219	2009-02-28 21:49:00	Tested ram in other PC. Was a bit grumpy to start with, shutting down almost immediately, then booting and failing to find the network. Reboot again shutting down so I switched slots. Then it gave a loud string of beeps so I was able to properly test the speaker I was also testing!! Back to the orig slot and it started. This corsair isnt on that mobo list as supported ram (M2NPV-MX) so maybe that's why the runaround? Still this doesnt answer why the M4A78 board is silent...	Tbird650 (6754)
752220	2009-02-28 21:53:00	Maybe your RAM is faulty then	Agent_24 (57)

The RAM is almost definitely faulty, try to get a replacement. The first time you booted, did you hear a crack or anything? My guess on this is mobo+ram is faulty.....	Blam (54)
752222	2009-02-28 22:10:00	If the ram stuffs up on another machine, then something with the ram. Cannot remember, but I think, when I got my system, the ram arrived late, I turned it on but it made no noises :D Power goes, fans spin, a all in one motherboard with video ... power capacity should not be an issue. Dell etc .. run on much lower ones. Re: HDD. Just guessing here. It may be easier to set the motherboard settings to ATA for the HDD. Unless you have Windows XP with a SP installed with it or Vista cos the earlier XP does not support SATA. But usually ATA are by default. And, of course, even if you had no HDD it should still boot into bios and should still beep. What I would do is take out all the cards and drives, leave the RAM there from my experience.	Nomad (952)
752223	2009-02-28 22:25:00	Theres a dual core cpu on my M2NPV-MX. From what I can tell it may be compatible?? There's 2 4200 cpu's listed as being supported. CPUID reports it as: AMD Athlon 64 x2 4200+ codename windsor. Family:F, Model: B, Stepping:2, Revision: BH-F2 Asus M4A78 Pro supports either of these 4200's Athlon 64 X2 4200+ (DO),512Kx2,rev.G2,65W,SocketAM2 or Athlon 64 X2 4200+ (DD),512Kx2,rev.G1,65W,SocketAM2 Is mine one of these? It's a bit confusing!! Is it worth a try isolate component ?? Is the revision an issue? The first time you booted, did you hear a crack or anything? My guess on this is mobo+ram is faulty..... No sounds like that. It could still be faulty as you say though doesnt explain why the m4A78 board is ghostly silent. Also have now tried the stick of ram from the M2NPV-MX machine here, it's a adata 2gb module. The numbers don't QUITE match according to the manual but in any case no improvement and still no beeps.

752224	2009-02-28 22:47:00	If you get no beeps etc.. is it just a blank black screen? That means you cannot even flash the bios right? Take the HDD out. Then, I think it is either the mobo or the cpu that is faulty. Video is builtin so that is eliminated. Are they near by, if you bought the 2 parts from them, I may take it back for warranty. Obviously, if you have a compatible motherboard or cpu from somewhere else I may do that. So to isolate it.	Nomad (952)
