Gigabyte DS3P Cycl Reboot - or Me Too

Gigabyte DS3 Cycl Reboot - or Me Too

Was going to put this in the Gigabyte Guide but its too long I think.

EDIT: Note the actual mobo is a DS3, not DS3P like the subject said, my bad, but I think it makes little difference the exact version of GA965P.

So, add my name to the list of people experiencing cycle boot. Starts, no post, no fan spinning or beeps then shuts down at which point the fan suddenly starts spinning for a second. Repeat in loop. In fact my testing shows that it behaves exactly the same if the fan is unplugged. This before any overclock.

However, I had it working perfectly, no problems, proving my system did work. I had installed everything, playing games all running flawlessly except for a noisy fan. So I went into bios and set the smart fan control method to Intel QST. Saved changes and since then I've had cycle boot.

I've tried everything I can possibly think of with no luck. In no particular order:
1. Putting my 2GB 800MHz of Geil in DDRII1 and DDRII2 like the manual says
2. Using the red slots
3. Using older working Geil 667 MHz from another PC
4. Unplugging everything except ram, 1 HD and graphic card
5. Lifting up motherboard to ensure case not short circuiting it
6. Putting a jumper on CLEAR_CMS _and_ taking out the battery for over an hour. Yes, I unplugged powercord

7. Rechecking all cables.
8. Checking if fan is properly seated (question: Can poor contact cause my problem, as I've used only the out-of-the-box fan with no additional contact gel?)

Guess I'm gonna have to RMA it unless anyone has any further ideas?

System basics:
GeIL 2GB PC6400C4 800MHz Ultra Low Latency DDR2 Dual
Gigabyte GA_965P_DS3P (Socket 775) PCI-Express DDR2
"LGA775 Conroe" 1.86GHz (1066FSB) - Retail
Hiper HPU-4M580 Type R 580W ATX2.2 PSU - Black

All from overclockers...

Cheers

Are you running the latest BIOS (F5)?

Cupra · 7 May 2007 at 12:45

id say its board rma time

Dancer · 7 May 2007 at 13:28

I never did uppgrade the bios and now its not possible.

MeatLoaf · 7 May 2007 at 14:00

Try the GFX in the lower slot

I've had something similar with my DS3P but all I did to resolve it was remove the PSU mobo connector whilst it was in the cycle boot loop, this fixed it for me.

Not an expert but I personally think that this problem is caused but the dual BIOS, main BIOS boots up and thinks there's a problem so it reboots using the alternate BIOS which it also can't boot from so the cycle continues.

You may just be a genius! I hope so because I don't know what to do next.

As you said if I remove the ATX 12V the fan (both CPU and GPU) does indeed start up and its running... however there is no output on the monitor and the keyboard isn't being detected. Neither does it start the HD.

So now I can stop it doing the boot cycle but I still can't get to the bios or do anything. At least its something, but I can't see what I might do next. Plugging the 12V back in means it just resumes its cycle.

Dancer · 7 May 2007 at 16:25

Just a small correction, it does seem that the HD starts spinning too (noticed how quietly it boots when HD was disconnected) and there is at least power to the keyboard. Why there is no output to the monitor I don't know and so I don't even know if the bios starts or not, my guess would be not though...

I get the boot recycling with my DS4(latest bios) from time to time.I remove the power plug(as already said) & leave it for 5 mins & then replug it back in.It then starts normally.

Dancer · 7 May 2007 at 17:41

Well removing the power plug (+ batter) for over an hour did nothing for me. Removing the 12V ATX power connector to the motherboard does stop the cycle but there is nothing happening, ie nothing on the monitor, nothing loading on the HD... just spinning fans. I'm gonna have to RMA it I suppose, just sad when it's a brand new system and was running fine for over a day as in my initial post.

Have you tried the gfx in the other slot as i suggested earlier?

No, there is only one PCI-E slot so I'm rather limited in that respect. All my other graphic cards are AGP so I'm a bit stuck. I might borrow a simple ATI PCI card from work tomorrow just to try but I'm not getting my hopes up. I'm still wondering how removing the PSU mobo connector fixed it for IAmATeaf. Was it the 12V ATX you removed (I've read its not really healthy to boot without it, but I don't know) as that does keep the machine running but without anything else happening so I'm a bit stuck for what to do next.

Teal · 7 May 2007 at 20:21

The DS3P has 2 PCI-E slots, it supports Crossfire after all or am I missing something?

musicman · 7 May 2007 at 20:27

my DS3P has 2 (1x16 1x4)

Dancer · 7 May 2007 at 20:59

Yes I mistakenly posted Gigabyte GA_965P_DS3P, when I meant GA_965P_DS3, sorry now I see why you suggested trying the other PCI-E slot. I'll try a PCI card tomorrow but I doubt it'll make a difference. Hope is fading.

IAmATeaf · 7 May 2007 at 22:41

Try booting it up without the vid card, then power down, plug the card in and see if it'll boot to the BIOS.

MeatLoaf · 7 May 2007 at 23:04

Its also worth unplugging any USB devices you may gave, and any add in cards apart from the GFX card

Tried, but no go. I don't think it actually ever booted up though even if the HD was spinning. Doesn't seem to make any difference whether graphic card is slotted or not.

Appreciate the help though. After spending the whole day reading about gigabyte card and cyclic boot problems I think my faith in gigabyte has dropped through the floor. I've found a couple of other posters (on other forums) who also enabled Intel QST and ended up where I am. At least one such person RMA'd the mobo and that solved it, but he then changed to another cpu fan and the same problem occurred.

I even got some zalman contact gel out and reseated my PSU but still no change. This is only my fourth PC I've built from scratch, but I've never been this utterly stuck before.

I'm booting with only GFX card (and without it), 160GB SATAII HD (tried without it also), a USB keyboard (tried PS/2 keyboard too) and 1 or 2 GB of RAM (tried in various slots). I've certainly tried that's for sure.

I had the same problem with a DQ6, it would boot every time with a PCI graphics card, soon as I put the PCIE card back in it would go into the endless booting loop again. If you could get a PCI card you should be able to boot up then at least you would be able to flash the bios, if its still the same after a bios flash ask for an RMA.
