a98pmalcolm Posted February 17, 2011 Share Posted February 17, 2011 got a new mobo from gigabyte in exchange of my old one. hooked it all up. press the power button then... turns on for 2 seconds, turned off for 2 seconds. turns on turns off repeatedly on its own. been looking on google and people say it a symtem of a supply needing replacing. but this 1000w one i have is only a year old!! any ideas or opinions guys/girls? thanks paul Quote Link to comment Share on other sites More sharing options...
Angarak Posted February 17, 2011 Share Posted February 17, 2011 Do you have a spare PSU you could try to eliminate the PSU as the cause? PSU would be my first guess - regardless of how new it is. Second guess would be the motherboard shorting out on the case - you could take the motherboard out of the case and try booting it up on a piece of cardboard to eliminate that as the cause (do not boot up on the plastic bag the motherboard comes in!). Failing that, remove all add-on cards and try booting with minimal add-ons - 1 stick ram, 1 HD, etc and if it boots OK then add 1 thing at a time until the problem presents itself to identify the culprit.

DamanC Posted February 18, 2011 Share Posted February 18, 2011 95% of the time its the PSU or the Mobo. Take it all out the case, does it work? Remove all other cards, does it work? Who makes your PSU? Try another PSU. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 19, 2011 Author Share Posted February 19, 2011 hay daman. its an i cute psu.. i knows its not to great but a 1000w @ £100 couldnt miss a good price lol its a brand new mobo that gigabyte sent me so its highly unlikely that. My local computer shop are allowing me to buy a new psu and if its not the case i can return it. im going either coolmaster or corsair this time.

DamanC Posted February 20, 2011 Share Posted February 20, 2011 CM PSU's are not that great imo. It has to be a corsair unit or if need be, Antec. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 20, 2011 Author Share Posted February 20, 2011 i saw looking at the corsair ones. i really like corsair stuff. i was looking at the ax850 but i dont know if that will be enough? i have an antec 900 case 2 ATI HD4850 cards crossfired H70 water cooling Gigabyte EP45-DS3 which has an 8pin connector rather than the typical 4 2 HDD's creative sound card with front pannel extra fan on the side pannel RAM coolers will 850 be powerfull enough? The Corsair HX 1000 ATX is nice but its longer than a normal and iv drilled a whole next to my power pack for cable management so idealy needs to see the same size as the one i have now. maybe the antec high current gamer 900w as its a little more powerful and its the correct size for the case.

Scott Posted February 20, 2011 Share Posted February 20, 2011 Much more than enough IMO. Quote Link to comment Share on other sites More sharing options...
DamanC Posted February 20, 2011 Share Posted February 20, 2011 A TX 650 will happily power that lot If you have money to spare then I can higly recomend a HX750. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 21, 2011 Author Share Posted February 21, 2011 i had a 600w gone on me with a lil less than this. so the cosair over the antec psu? Quote Link to comment Share on other sites More sharing options...
Wez Posted February 21, 2011 Share Posted February 21, 2011 The cheap PSUs can fail well below there supposed rating, Corsair should do the trick. Quote Link to comment Share on other sites More sharing options...

Morpheus Posted February 21, 2011 Share Posted February 21, 2011 I've had this dozens of times during over-clocking. Unlikely to be the PSU if it boots atall, so don't worry about that yet. Sounds like DDR timing is wrong. Have you checked that the BIOS settings for the CPU and RAM frequencies are correct? The board is probably trying to find the correct settings from the DRAM timing table, (a list of clock frequencies, e.g. 9-9-9-24 or 5-5-5-8 to use at given FSB frequencies) but the memory voltage might be too low or CPU multiplier wrong or memory clocked too fast for the voltage. It's a common symptom of CPU frequency too high as well but the board should reset the BIOS after 4 failed attempts if it's anything like my Gigabyte board. Let it run until it reboots 4 times or press delete during boot as soon as you see the 'splash screen' or any text appear to enter the BIOS, (Basic Input Output System), which will allow changes to be made. Don't do this unless you know exactly what you're doing though. Any questions, just ask. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 21, 2011 Author Share Posted February 21, 2011 hi mate. it wont even boot to see bios. as soon as i turn on... it shut off, then turns on its self, then off it self like some1 flicking a light switch.. the board is fine with this ram as i sent off my old gigabyte board with my corsair ram. so they new what to send back to me. i totaly understand with overclocking these gigabyte boards and when they overclock fail and double boot, been overclocking quite a bit. with previous set ups etc..

Have you reset CMOS yet? BIOS sounds corrupted. Could also be a bad DDR module. Had it from that too. Do you have a PSU tester like this? http://cgi.ebay.co.uk/ATX-POWER-SUPPLY-TESTER-20-24-PIN-SATA-LCD-PSU-/200572532345?pt=UK_Computing_PowerSupplies_EH&hash=item2eb30df679 Again, the last resort at this stage.

Angarak Posted February 21, 2011 Share Posted February 21, 2011 Take all the memory out, boot it up, does it get so far as giving you 4 beeps to indicate memory error (as there is none) without restarting? If it continues rebooting every 2 seconds after that it isnt your memory. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 22, 2011 Author Share Posted February 22, 2011 its a brand new board sent from gigabyte, never run. the memory i have i had run memtests on the old board for hours, and all ok. Also gigabyte ran tests on my memory aswell and all is well. my local pc shop said if its not the psu i can return the one i bought from them..

Morpheus Posted February 22, 2011 Share Posted February 22, 2011 Yep, had exactly the same thing happen loads of times, (when I've pushed the CPU too far and errors crashed the BIOS). My board sometimes takes 30 seconds or so with the jumper on CMOS pins to clear it. Does it in a second one time but much longer another so keep trying to clear CMOS, p.i.t.a. that it is. Try it with only one memory module and cycle through them, one at a time, if that won't work. Also none, as already suggested by 'Angarak'. (btw, Branners might change it to correct spelling unless that was intentional?). Trust me, this is BIOS related. Either the memory isn't compatible, plugged in properly or the CPU is not quite configured. This always happened though, when setting the memory frequencies out of range, (too tight or low clocks), but it would reset after 4 failed attempts and it would keep doing it like yours only when the BIOS was corrupted and it couldn't reset itself. Clearing CMOS properly should get you into BIOS again. Done it countless times but it can take several attempts to actually clear CMOS properly so leave the jumper connector on for longer.

a98pmalcolm Posted February 22, 2011 Author Share Posted February 22, 2011 hi mate. iv tryed all different memory slots, also different branded memory iv had spare iv never had this board turned on b4 it did it as soon as i turned it on so i havent dont any overclocking or adjustments. ok will attempt to clear the cmos again thanks Quote Link to comment Share on other sites More sharing options...

Mine can be a mare. It's a GA-P35C-DS3R and probably has the same BIOS chip. You might even have been sent a customer return, repackaged. Might check out with diagnostics but BIOS could still be dodgy. Good luck. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 22, 2011 Author Share Posted February 22, 2011 hi mate.. tryed again.. a few times even left it over a minute. even took the batuary out and left it still no luck. i will email gigabyte see what they say Quote Link to comment Share on other sites More sharing options...
