Boot Problem with GA-P35-DS3R

[The Oven]

I have had this system running for about 3 years now.
I've always had hit and miss luck with overclocking it

Yesterday I tried again, adjusting oc, and also the memory timings and voltage

I have used these settings before but could have put the wrong info

The system started to reboot after saving settings, then powered down and went to reboot but with no signal to monitor


This used to happen before when i would OC and try to reboot, it would cycle trying to boot and never make it


I used to unplug it for a few min and it would start back up

no luck this time

I tried resetting the cmos several times
removed battery
used jumper
even let it sit for a few hours with everything unplugged except the proc

still will not post

All the fans and such spin up for about 3 sec then it powers down, then back up and just sits there, with all it's fans spinning

no signal to monitor

I don't have any other parts or system I can hook it up to

I don't have a internal speaker, would that be worthwhile to get?

would the beeps tell me what is wrong?


If I cleared the cmos why wont it start up?
could the memory have gotten fried?

I have a P35 Abit IP35-E with a similar problem. It seemed to improve after I did one of the following or maybe all of them helped enough:

Flash Latest BIOS - even if it's a beta that is newest.
Pull all but one memory module - temporarily, and try it in different slots clearing CMOS between attempts, and swap in only one other memory module to retry.
Swap in a different video card, even some ancient PCI card if that is all you can find or buy for dirt cheap (old mom-n-pop computer shops may practically give it to you for free if someone on the FS/FT forum won't)... IIRC at one time some cards in particular that my bios didn't like were 7600GT or similar.

Another thing I noticed with mine is it would get into a mood where it didn't like having an external USB2 HDD connected till after windows finished booting.

Of course at this point other more generic things could have gone wrong like capacitor(s) or PSU gradually failing.
