Hi guys just got home from shopping and tried powering my comp up press the power button and get nothing :confused:

rofl babyface *** are the odds? just curious what psu have you got? and which dfi board was it? did u get the standby power led light on the board?

babyface uk · 8 Apr 2006 at 17:57

Psu is a antec neohe 500watt, and it is the DFI Ultra D mobo and yes got the standby lights on, but nobodys home. Bro's got it at the moment as hes got plenty of spares ( I haven't got any ), will update if he sorts the problem out.

hmm kk, i thought it could be a psu problem as everything i see on the net relates back to the psu, but i tried a really old clapped out 400w psu but still get the same problem? i think it could be the psu but not 100% at the minute and just want to check first before i fork out for a seasonic psu!

*note i currently have a Hiper Type-R Modular psu (580w)

oh FFS, well did he say if he worked out the problem? this is annoying the hell out of me cos my comp worked fine this morning :confused:

If a replacement PSU won't help and the motherboard doesn't make any beeps, then the chances are that the motherboard has died. If it was the RAM, the mobo would beep as it would for the graphics. It could be the cpu but that is relatively unlikely. Anything else and the system would work but with POST errors.

When mine didn't boot last week after a re-build I bought a replacement identical mobo and it worked immediately after the swap-out. Had it not done, I could have sent the mobo back under the Distance Selling Act. Becuase it did, I now know that the mobo died so can start to look at whether I can RMA the broken one.

Very strange :S

Tried reseting CMOS?

xirokx · 8 Apr 2006 at 18:53

I'm wiv Mike....

Its a case of trial and error....First point of call would be the mobo in this case and the CPU.....

Get testing lads....

Let us know how you get on

ok, got it back and psu is at fault, bro tried an old 450w psu and works ok, strange thing is he hasn't connnected the molex power conector or floppy connector on the mobo and it boots ok, when I first built the machine it would even post until these 2 power connectors where on, oh well.

Yeah the DFI boards seem fussy about this but i got away with only putting the 4 pin molex in and leaving the floppy out.

As for your problum reset CMOS change RAM slots only put 1 in. Strip it down to the essentals to get past POST see what happens

harris1986 · 9 Apr 2006 at 15:15

hmm well i tried a really old non atx 2.0 psu and that sent power to the mobo but nothing booted so i'm now at a loss of is it the psu or has my mobo actually died? if it is my mobo would getting a identical replacement mean that i have to completely reformatt or could i just set it up and away i go with the existing drivers on my hard drive? (hope i don't need to reformatt as i have a lot of vital files on my hard drive)

babyface uk · 9 Apr 2006 at 15:57

If its exactly the same mobo you should get away with not haveing to reformat.

ok just gone round to a friends house and with the same psu but using his cable it has powered on but i get the 3 led's on the diagnostic i.e. cpu detection :S and it won't get past this stage, any ideas now? tell me my cpu hasn't randomly died on me

harris1986 · 9 Apr 2006 at 18:22

ok so, now i am on my comp again YAY

but, when it won't boot with 2 sticks of ram both sticks work fine on there own but i have tried all ram slots and i get the same problem. Now even with 1 stick of ram when i go into bios to sort settings out again after saving settings it goes to reboot and i get the same problem everything is fireing up but no screen and have 2 leds on my mobo, so i have to clear cmos bypass it when booting up and it boots fine.
