Just come back from holiday to find my PC has been stuck in an endless reboot loop. The graphics card fan had also been making a horrendous noise so ive stuck a temporary one in there (it was on teh way out anyway).

Now I can boot up the machine, it'll bleep once as normal. It'll detect the memory and hard drives, and where the POST screen would usually flick to its second page, it goes blank for a few seconds and the machien reboots. I cannot get into the BIOS or anything. The only thing that made a difference was unplugging all the hard drives which get me to the second POST page followed by a boot disk error, as normal for no hard drives.

I'm pretty stumped tbh. I've tried all the hard drives individually, the POST never gets past detecting IDE drives if my windows boot drive isnt plugged in. I've tried 2 different sets of RAM to get rid of any possible memory errors and that hasn't made a difference either. The only thing I can think of really is the motherboard has had a hissy fit and won't work properly any more or my overclock which has been stable for a few weeks has gone all wobbly. Spec is as follows:

Core2 6300 @ 2.6Ghz (Arctic Freezer 7 Pro Rev2)
Gigabyte GA-965P-DS3 (F7 Bios I think)
2GB Geil PC6400 and 4GB OCZ PC6400
3x SATA Hard drives
Currently an 8800GT graphics card but changing hasn't made a difference.
Windows 7 64 bit

Help! :(

Well this is weird. I've discovered that only one out of my 4 (non RAID) sata ports works. Both sockets on block 2 cause infinite reboots. First socket on block 1 gets to teh second post screen then just hangs forever with the blinking dash at the bottom. However port 2 on block 1 is fine. Totally normal. What the hell could have caused this? Is the mobo on the way out? Would a bios flash help? Really in unknown territory here so some aadvice would be great.
 
couple of years ago i came back off holiday to find my pc dead.i bought a new psu only to find all my hard drives(4) were wiped and fried.next door told me we had a thunder storm and lightening hit a lamp post at the end of the road.
 
I'm having a similar issue with an ASUS P5B-Deluxe but I just haven't found the time to tinker with it I solved it in the past... but its been in storage and only got it out recently for my brother... anyways can you access the BIOS? have you tried re-setting default values to see what happens? also try powering it down and then holding the power button (without releasing) until it powers off on some motherboards this can also clear the cmos try it twice just to be sure... also is their a clear CMOS jumper try that too hope something I've said helps!

I've already done that. See post #3 to see how it stands at the moment.

Sorry I must have been skimming the title and missed the details in post #3!

It is unnusual it features the same chipset as my motherboard 965 Express and when I bought mine I suffered from some form of SATA issue... trying to think of the top of my head how I fixed it....

A starting point might be to refer to the latest motherboard manual for your revision of this motherboard from the link below;

BTW, post #3 doesn't say if you have succesfully accessed the BIOS?

If so, what happens when you unplug the HDD? does the same blinking dash occur?
 
Sorry yes, I have accesed the bios. I basically have full control of the machine now apart from 3 of the 4 normal (not the raid) Sata ports. I'll outline the problem below:

SATA Block 1:
PORT 1: Any HDD plugged in just hangs with the blinking dash, very slow to pick up and do anything. Never gets past final page of POST.
PORT 2: Works fine with any HD, though can only fully test with my boot drive obviously.

SATA Block 2:
PORT 1: Causes PC to endlessly reboot with any HD plugged in after HD list pops up on first POST page.
PORT 2: As above.

Can't find anything in the manual that is of any use really. With no hard drives plugged in, the system boots as normal until it gives me a disk boot error due to nothing to boot from.
