[Resolved] Gigabyte P35-DS4 stuck on constant reboot loop
Hi guys,
I've had my Gigabyte P35-DS4 running fine since last August. Today I changed a few settings in the BIOS (reset OC settings to default and enabled USB mouse & keyboard support) and saved/exited.
But in got stuck in a constant reboot loop. It powers on for about 3-4 seconds and then powers off again, on, off, on, off... in a constant loop. It never gets as far as even powering up the monitor and no beeps either.
I've unplugged, pulled the battery and shorted the cmos jumper (left for 30+ mins) but that's not fixed it.
Any suggestions how to proceed?

try removing all usb devices.

Already done that - unplugged usb mouse and keyboard, and replaced with a ps2 keyboard. Still no go.

Got it fixed.
Leaving the battery out for an hour and then booting whilst holding down the Insert key allowed it to recover. Had to reset the BIOS though.

where did you get that solution from?

Re: Gigabyte P35-DS4 stuck on constant reboot loop
I have:
-Gigabyte EP43-UD3L
-Intel Core 2 Duo E8400
-2GB G.skill DDR2-1066 (2x1GB)
-nVidia 880gtx 768mb
I experienced the reboot loop after forced shutdowns (holding power button down for 5 seconds to shut power off).
I found that the reboot loop went away if I removed my PCI-E card and instead used an old Mach64 PCI graphics card. Obviously I can't live without using a PCI-E graphics card, so I next focused on the memory. I put back in the PCI-E card and swapped out the DDR2-1066 G.skill ram for some slower DDR2-800 Corsair ram (2x512mb). The problem went away. So why won't the G.skill work?
After seeing a post on another forum, I figured I'd try setting the voltage for the memory at 1.8v. It had been set at auto, and I assume was using 2.0 to 2.1 volts which is what the G.skill specifies. I bumped it down to 1.8v and the problem went away. I put it at 1.9v and it was still good. At 2.0v the problem came back.
Why the Gigabyte mobo cant's seem to supply the memory with 2v or higher without exhibiting the reboot loop problem I have no idea. But at least for now, there is a work around by setting your DDR voltage to 1.8v.
