Windows 7 64bit can't shutdown, always restart

[Dark Mantis]

The first thing that stand out especially if it is a bit older is the PSU being underpowered. The thing is power supplies deteriorate with age and use,  the capacitors suffer from droop and the output drops. I would see if you can replace(test it) it with a new higher power model preferably something like the Gigabyte Odin or Corsair 650w at least to give you a bit of headroom for the future.

Many multiple fast beeps is often memory setting tRD (Static tRead Value) Set too low.

Please press Control + F1 on the MAIN page of your BIOS, the screen will flash, then enter the MIT Section and tell me if you see the above mentioned setting anywhere in your memory settings.   Sorry, I can't remember if 965P has this or not.

If you do not have the setting I would try to borrow a different set of memory from someone for testing if you can to see if that is the issue or not.

*Edit*

Actually, just checked your BIOS and you do not have this option.   Please try setting Performance Enhance to standard if you do not have it set that way already, then if the same occurs please try High Speed Dram setting option 1 and 2 and see if either of those help.

I agree with Dark Mantis as well, if you can please test with another newer or larger PSU to see if that alleviates either issue.

Thanks guys for your quick replies, I will check the settings.

Also, now that you mention it could be memory, I will put the old memory back in to test. Only reason I changed the memory recently was that I got them for next to nothing and that my previous 7Gb was mixed size and brands.

If using 4GB or more you will need to increase your NB voltage, keep that in mind.

Yes a very common problem that is easy to fix.

[roks]

Sorry, never messed around with these voltages, always went with the default, how do I change the NB voltage.

I will also try this when I get home tonight.

Thanks

It will tell you in your manual but it will be in the BIOS under the MIT section and labeled MCH control or similar. You only need to raise it by a little and see if it helps with the stability.

OK, I got myself into a irght mess last night, after resitting the rams, hoovering the any dust out, got frustrated rest the bios and the dmi data.

Now I've lot one of the raid 0 disk, it says 'non-member' for one of the disk, the other one still says member. overall the raid array 'failed'.

Any way I can get the data out?
If I remove the other disk amd make it non-member, will it delete the data or the raid info?
I thought then I can create the raid at it was before and get the data back?

[Dark Mantis]

You will have to rebuild the RAID to get the data back. Why it has dropped of is another matter. Have you moved the data cable to another port or anything like that?

[roks]

No, I did not touch the sata cables, I did how ever unplug the power from all hdd and mb.

Only good thing that came out of this is that after I thought I had nothing else to lose, I did a restore of bios from backup to main. Now the pc stay shutdown. Real proof will be once I've installed W7 again.

[Dark Mantis]

It's just one of those days for you isn't it? I wouldn't even touch the computer any more! 

[Lsdmeasap]

Anytime you reset the BIOS, flash it, or load Optimized or Fail Safe (Never suggested), always be sure to reboot RIGHT BACK to the BIOS to then set your RAID options again - otherwise if you try to load windows and forget to set RAID again you will corrupt your array.

Hope the reinstall goes smoothly for you!

Thanks for the tips,

It appears that I cannot boot from a USB stick and USD HDD works but extremely slow. Both these methods work ok and install Win7 quite fast on my old laptop.

I had to resort to DVD, even that was sloow, its been a while so I forgot to diable the floppy, and what a difference that made to the installation time.

Anyway, back to the original issue of rebooting and rapid beeps.
After the rebuild, its still doing it and it appears that when I put the PC to sleep, it goes in Hybrid-Sleep, turns everything off, because of the reboot issue it never stays of and thats when the rapid beeps sound.

[roks]

Cant belive my luck, it looks like its the motherboard, I tried two other PSU's One Antec and one unbraded, PC keeps restarting.

Now it restarts as soon as the rocker switch at back was turn on.

What buffles me is that every article I read about the PS_ON# says 5v= OFF and 0v= ON. When I measured the voltage on pin#16 on the power connector, it was complete opposite. when the pc was on it was 5.02v and when I shutdown, for the 2-3 seconds that it stays off it reads 0.86v.

Is there a way to fix this? maybe the logic driver has gone wakky, is that replaceable?

P.S. Gigabyte we're not interested, after a week their answer was 'its out of warranty'.

[Dark Mantis]

You haven't got a sticky switch on the case have you?
