Okay to make a long story long. I pull the battery from my spare board and notice I'm gonna have to pull the upper video card to get to the battery on the board, go ahead and do it. Replace battery, replace video card, put memory in all 4 slots. Reconnect power supply cord. Press button and nothing but hi speed fans, no post, NO VIDEO!!!!! Make sure the video boards are seated fully, they are. reset button not even getting it going now, about to lose my mind then figure maybe the battery is just as old since they're on the same board...... Then it dawns on me I forgot to connect the 6 pin power to the video card......... shut it down, connect the plug, hit the start button and starts booting, go into setup and make sure everything is where I want it, reboot, working so far!!!!! Keeping my fingers crossed as It was hit or miss sometimes, looking good though. It's never this easy.......
Can't believe I missed the time drag you'd initially mentioned...cmos bat drain...for some reason I'd thought this was a newer system...should have caught that clue. Kudos to Krup for catching that...now that's troubleshooting!

Yeah But I spoke too soon, still rebooting....There's a chance the battery that was on the spare board is as old and weak as the other one, I'll throw a new battery into it this weekend to make sure...
Hmmm...doesn't seem likely a CMOS battery in an unused MB would be that discharged, unless you've had that MB for several years. Standard lifetime is around 10 years, depending on usage...and I'm doubting we're talking about a 10 year old MB here...
Edited to add...after trying my previous troubleshooting suggestions, and if PS isn't the problem, may be time to make use of that spare MB. I've had extraordinary performance from ASUS MBs myself...personally, I won't buy one from another manufacturer, but it's always possible that one may be bad...all it takes is one bad solder...

Yeah I've liked Asus for many many years, Liked ABIT too, but think they must have gone under long ago.
I take it a brand new CMOS bat. made no difference?

Just threw one in this afternoon surprise night off work, So far so good. Tried booting and of course since I removed the power cord and battery, I needed to hit the reset switch, it had hung up doing nothing. Went into BIOS and made sure everything was right to my liking and booted right up. Played some USAF, been farting around for about 3 hours with no reboot. Fingers crossed, usually doesn't last this long without rebooting.
Going on 5-6 hours of USAF and surfing all good. Getting my hopes up.
Good deal, and kudos again to Roger for calling it!

Yeah looking like it might be the real deal. I've been running now for almost 10 hours with a deliberate restart, no reboots and no hangups when restarting. I thank you both, you've always been a wealth of info Oswald. Thanks Roger, think you nailed this one. What are the odds that two batteries would be weak though, but when you think about it the boards were built about the same time in 2010 so the batteries should both be in the same condition. I don't think it would make a difference whether the board is being used or not, the battery would always have power to the BIOS chip wouldn't it? Even if it didn't it still isn't being recharged so the life of the battery is going to be the same.
Very true...though from my research, seems 5 years is somewhat short for expected lifecycle for a CMOS bat...
Course ASUS may have gotten that batch from China, which would of course dictate halving any ratings or lifecycle.

Yes the battery ALWAYS supplies power to the CMOS settiings / Real Time Clock chip (unless it's dead)
The real time clock and system (BIOS) settings chip only draws microamperes. At that rate, a common CR-2032 coin cell should last around 7 to 10 years.
Older systems used a ni-cd battery that was recharged whenever the computer was on. But usually the battery was overcharged so when the PC started acting up, the technician would find a blob of green corrosion where the battery used to be. Plus it was soldered to the board, so it required taking the PC apart, unsoldering the battery and soldering in a new one. That is, if the corrosion didn't also dissolve away board traces and ruin the whole motherboard (which usually did happen).
Newer ones use the lithium coin cell, it's NOT recharged and doesn't need to be because it draws such little power. Also, it is always powering the CMOS chip whether or not the PC power is on.
If you have a voltmeter, put the negative lead to the computer frame (ground) and the red lead to the exposed top of the CMOS battery (setting your meter to DC volts). A new battery should read around 3.1 to 3.2 volts, one that's been in a computer for a few years will read around 3.0 and under 3.0 it's time to replace it.

Thanks again Roger, two or three days now, no reboots, no hanging before post ect. You called it.Yes the battery ALWAYS supplies power to the CMOS settiings / Real Time Clock chip (unless it's dead)

SOB!!!!! Started doing it again! Guess i'll throw in a new power supply and then change out the motherboard if that isn't it. SOB.....Thought we had it nailed.
Hmmm explain this one guys, Now that I put a new CMOS battery in, It will hang when the power button is pressed with high speed fans running, but not testing dvd's or floppy or doing anything, I have to press the reset button repeatedly then it will boot normally as long as I don't have quick boot enabled in bios, I'll let it start the memory test then esc out and it boots normally goes into windows, and never reboots, I can run it for 10 hours straight without a reboot, but it will have the finicky problem of getting started! Wierd. Should I take a chance and flash the bios? Bios virus maybe? Or more likely power supply or motherboard going?
If you've reset everything BIOS wise, I think the power supply is your next best culprit.
But, have you replaced all cables? MB to HD...different PS to HD, etc.
You mentioned the system not going on to recognize the DVDR...get it the fuck out of the mix until you have stability...
Eliminate all but the base...PS, MB, CPU, single MEM SDRAM, boot HD...
You can't eliminate the problem if you don't clarify the question.

Yeah I was thinking the same, getting some kind of spiking or low voltage I'm betting even though my tester says the PS is good. Just put a new one in. Booted right up instead of playing reset before post and press the reset button games. Fingers crossed, as it started rebooting in windows last night too again and today with the old PS.
No such luck, not the PS, had a reboot in windows. Taking one of the video cards out now. Just so random. It will run for 10 hours one day without a problem, then bam reboot other times in 5 minutes.
Okay rebooted again with one video card, trying the other one.

Okay Oswald, I just noticed something that coincides with your statement about replacing cables. When I went to put on the side cover which pushes against the SATA and Power cables on the HD I'm using right now, it rebooted. I let it boot back into windows, then pushed on the cables by hand, it rebooted. Since it's a new power supply, I replaced the SATA cable and really have my fingers crossed that the pressure on the cable may have cracked the wiring inside just enough to make intermittent contact problems..... Wouldn't that be sweet if it was just a SATA cable!
