Hi guys, You may remember me recently banging on about my mobo and psu dying (see Hardware & Overclocking). My replacement mobo came today and a new OCZ GameXstream 600W. I changed all the parts over, put the new 7900gt in, connected all the cables, whacked the power on and despite everything 'powering up' (fans etc) ..... nothing, no post. Not video output at all, not even the GPU's bios screen or anything that will trigger the monitor from standby. Ok I thought, 'I've probably not connected something up properly' and proceeded to check all my plugs etc. I've checked the obvious (CPU, HSF, RAM etc) as well as all my cables and plugs - monitor cable, 24pin Atx, 4pin CPU, 6pin pci express, sata plugs (data and power). I even tried clearing the RTC. Then I wondered if maybe the 7900gt was dead, so I tried a 7800gt and a 6200tc but neither made any difference. Can't think of anything I've missed but I'm hoping it's just a case of 'can't see the woods for the trees'. I can't deal with another bloomin RMA
Okay, so I just found this reply to a similar query and it's strange. No keyboard lights seem come up by themselves but just after the system is powered up I am able to turn NumLock on and off one or two times. Neither scroll lock or caps lock can be enabled however.
It's a pain, but try taking everything out of the board (including the CPU) and starting it that way with a speaker attached. If it beeps angrily then the board is at least partially OK and you can start adding things back in.
I have read that new Asus boards esp. don't post with certain ram. Check your ram and try some slower ram and other brands if possible. Maybe go to a local store and buy some cheap stuff so you can update bios.
Had the same problem on a mobo and tried everything I could think of to fix it, no luck. But the motherboard would beep everytime I turned is on, so I looked up the beep an it turned out that the beep meant the memory was bad. If it worked for me maybe it would work for you, try differnt memory.
You want to good news or the bad news? LOL - well if you get so far as to be able to cycle the Numlock even once (and the LED cycles as well) this basically means you have at least made it past memory detection - this is good news, your memory should be ok . . . Its kinda serious though that the scroll lock and caps lock don't work. This may sound odd, but can you try a different ps/2 keyboard? I would kinda try hitmans approach, but I would keep only the CPU and memory, detach everything else, and see how that goes. Then try attaching either a video card (the smaller and more basic the better) or a keyboard or a floppy drive and see if any of them "act right". Did you try to flash a new version of the BIOS? This should be possible even without booting, but it might not be something the MoBo manufacturer will tell you about - so it may not be an option. .
Hi guys, Thanks for the help Sorry I haven't replied sooner, had to shoot out yesterday and didn't get a chance to faff about with it again until this morning. Many of you were right, it looks like it was the memory that was causing probs. I tried nothing but the CPU and 1 stick of RAM in the B1 slot (manual states that this is the primary RAM slot to use with a single stick) and it still wouldn't post. Just for the sake of completeness, I swapped it for the other stick, tried again and voila! It posted! It was doing some funky stuff on the desktop, CPU-Z didn't recognise my processor etc but I flashed to the latest BIOS and re-inserted both RAM sticks in dual channel. Now Memtest seems to think that they're nice and healthy I remember a while back, Hitman recommended the GSkill HZs and somebody said that there was a history of compatability issues with my mobo. Others chipped in to say they'd had no problems however. I took Hitman's advice because he's a very knowledgable chap Best guess I can make is that earlier versions of the BIOS were not good chums with the GSkill HZs and whether by luck or judgement (they're still not on the approved vendors list) they now seem to work perfectly with the newest BIOS. The only thing I did notice though, is that the RAM stick in the A1 (leftmost blue) slot seems very 'loose' for want of a better word. I took it out and replced it a couple of times because I thought I was just being a clumsy oaf lol. Whilst the stick in B1 is solid as a rock, the one in A1 easily moves side to side. But well, it works for now. Thanks again for all the help guys, you saved me a very embarassing RMA process P.S. Anybody wanna buy my old mobo cheap? It has a misterious illness.
Glad you got it sorted mate, t's always a bitch when things don't work. What's wrong with the old one?
Cheers Krikkit. http://forums.bit-tech.net/showthread.php?t=117916 That's a linky for the prob with the old board (Seriously, read this first or nothing else is gonna make much sense ). TBH, I haven't tested it with the new psu so it could've just been the Enermax that was dead. But I doubt it. Basically, it won't power up and the standby LED just flashes when the board is supplied with power. I couldn't get it to 'power up' at all (i.e. no fan headers switch on or anything). An important thing to bare in mind however, is that it died silently. By that I mean there was no smoke or burning or anything of the kind. It just sorta slipped away in it's sleep. I'm not sure if that makes it a more realistic chance of repair by a knowledgabe individual but hey.
Some older nf4 asus boards had problems with some memory brands cause the bios assigned too low voltage on them by default.
