difinity Posted June 8, 2011 Report Posted June 8, 2011 Hard drive ? i've had a faulty one once that stopped the pc from booting up. It seems you've swopped nearly everything else. 1
gibbo_ap Posted June 8, 2011 Author Report Posted June 8, 2011 a collegue here has just suggested the case. i did actually think last night about the power button but at this point i had put the new mobo in which hasnt got power buttons on the mobo (i didnt think to use them when it was connected - doh)
difinity Posted June 8, 2011 Report Posted June 8, 2011 Remove the board and bench test, i've seen a few over the years that don't boot, due to screws and other metal objects shorting the board and the case. 1
2097 Posted June 8, 2011 Report Posted June 8, 2011 I had a PC here the other day that did the same thing . Except it wouldnt turn on with the power button or any i used . A screwdriver worked though shorting the two pins 1
Fatmas Posted June 8, 2011 Report Posted June 8, 2011 Sounds ridiculous but have you replaced all the SATA and IDE cables? I looked at one computer with similar symptoms and it was the IDE cable. Also, what @difinity said, ensure the case isn't shorting out components. 1
gibbo_ap Posted June 8, 2011 Author Report Posted June 8, 2011 Hard drive ? i've had a faulty one once that stopped the pc from booting up. It seems you've swopped nearly everything else. have tried without hdd, should still go to bios with hdd right?
Fatmas Posted June 8, 2011 Report Posted June 8, 2011 It should go to BIOS without HDD. *Whispers* Cables Cables Cables. SATA and IDE. 1

dhicks Posted June 8, 2011 Report Posted June 8, 2011 the computer powers up (fans spin, hdds too) I had a computer do exactly that, turns out I'd forgotten to plug the second motherboard power cable in - the small, four-pin one you sometimes get (is that a 12V connection?). 1

Marci Posted June 8, 2011 Report Posted June 8, 2011 (edited) Righty, first off, your AW9D should have a post probe on it which displays 2 digit boot and error codes - does it have anything on the display? If so, give us the error codes. If not, take mobo, CPU(+fan) and PSU. Wire up on bench. No ram, no graphics. Turn on via shorting powerpins momentarily with anything metallic. If fan spins up but you don't get any beeps whatsoever / no display on the postprobe, then either bios is corrupt and needs hotflashing, or CPU is dead, or mobo is dead beyond repair. If you DO get beeps, then all those components are fine. You now need to add ram and graphics and try it again to see if you can get to the POST screen. Only add ram one stick at once, testing each stick individually.

If all else fails, post in the "abit.care" section at Hexus.net's forums and see what advice official Abit reps give. Edited June 8, 2011 by Marci 1

Cheers Marci, the post probe displays 9.0. which upon investigation 9.0. Complete μGuru initial process AWARDBIOS take over booting job which isnt too clear but has made me think bios screwed, but the probibility of getting another mobo with screwed bios seems to slim. cheers
Marci Posted June 8, 2011 Report Posted June 8, 2011 Try the following: clear cmos, hold down insert key on keyboard, turn on. Otherwise, yep, bios chip is corrupt and needs hotflashing, or a new preprogrammed bios chip from bios-repair.co.uk. 1

I have to admit to doing that before as well, quite concerning till you realise and feel silly. 1
Cools Posted June 8, 2011 Report Posted June 8, 2011 hold down power button and reset at same time.. turn power off 1st then hold buttons turn on then off after 5 secons. then turn on and press the power button. have same symptoms with my gigabyte some months.. 1
gibbo_ap Posted June 14, 2011 Author Report Posted June 14, 2011 thanks for all the replys folks only had chance to have another mess over the weekend (middle of buying a house). Well after reading what you guys put i tried shorting the power pins (new mobo & psu).... and it worked! (well of a sort didnt have a hdd connected etc but i had post! but i couldnt leave it at that! i wanted my old mobo and psu in! so i spent an hour rebuilding it and tried the same thing and nothing! so when i have another chance i am going to take it out of the case and do it! Driving me up the wall atm! i just want my computer for when i move into the new house! need my portal 2 and wanna download duke!

Unless there the same MB make sure the power button is connected to the correct Pins . Read the MB manual to find out what ones are what and test using a screw driver . Looks like i was correct in the Power button being at fault to some extent . The one i have here does not turn on at all no matter what power button i use . Only way to turn it on is a screw driver for some reason .. 1
chazzy2501 Posted June 14, 2011 Report Posted June 14, 2011 Looking at your first post you've done everything you can to diagnose the fault. I'm afraid you must have made a mistake during those tests and need to go back and do them again. I did once have a faulty PSU that discretely killed all motherboards I plugged into it! So I had one killer psu a good psu and thanks to psu no.1 2 dead motherboards. Then 3 dead motherboards and a solution. 1
SYNACK Posted June 14, 2011 Report Posted June 14, 2011 Replace the case, had one case that was badly grounded or distorted or something and a MB just would not boot in it, replaced the case and it was fine. Cases can be reasonably cheap and it is probably the easiest solution. Bench test it outside the case and if it boots just replace the case. 1

Only way to turn it on is a screw driver for some reason .. since putting my orignal equipment in i have not connected the power button (partly as i believe that is partly whats at fault and partly as i cba to spend the time connecting it) i have been using screwdriver/mobo power button. still no joy
