Firstly When I shut down my system it restarts secondly will a SCSI Drive give better performance then a SATA Drive

I think its hardware issue..check the smps.

Ded9 First of all this motherboard has Asus Power Supply of 450 watts. Then at the time of motherboard change the mechanic detected that some of my power supply connectors were loose so he changed to CoolerMaster 600 watts as at that time the shop vendor did not have intermediate range power supplies. The system when shut down reboots. As I was not satisfied with the power supply I changed that CoolerMaster Supply of 600 watts to Corsair GS 800 watts when the shop vendor had such an intermediate power supply. So Corsair Power Supply is just a couple of days old but the system when set for shut down is rebooting since the last one week.

There may be a software issue also who knows?

I booted the computer in safe mode but it still reboots. I also have Windows vista nstalled on WD Raptor that also reboots while shutting down. So the chances are now much more for a hardware problem. What kind of hardware problem could it be again the motherboard spiked by a voltage?

What about the second part will I gain any significant improvement while transferring the operating system viz. Windows Seven from the WD Green SAta Drive to SeaGate SCSI Drive?

Make sure the cables are connected to the right ports..and its connected properly....double check...something to do with power cables..

Does it behave different when you remove the SCSI card from the PCI slot?

Now the Windows Seven is on the SCSI Disk. Remove the SCSI Card from the PCI-X slot then I will no longer be able to access it.

r.e. your 2nd question:   You didn't really provide enough details to answer the Caviar Green vs. Seagate performance question, but most likely the answer is Yes, you'll see a nice performance gain with the Seagate drive PROVIDING the following assumptions are correct:

=>  The Seagate is a 10k or 15k drive (Most 146GB drives are, so I assume you have one of these).   The areal density on these drives may be smaller than the Caviar Green, so the actual transfer rate may be similar -- but the access time will be notably faster on a 10k or 15k drive than on the green series drives (probably ~ half the access time).

=>  Your SCSI card is reasonably recent -- i.e. not an "ancient" SCSI-I or SCSI-II card with transfer rates below the capabiity of the drive

As for your reboot issue ==>  Is the system working okay, but simply rebooting when you tell it to shut down?     If so, check your BIOS and post what the current ACPI settings are.

Yes and what about any advantage of putting the SCSI Card 39160 on a PCI-X slot over the PCI-slot found on most of the consumer motherboards, because I know that the SCSI Card itself is a PCI-X Card. Paradoxically the Windows Seven Performance level for the Green Caviar Disk is 5.9 and for the SCSI HDD is 5.8. SCSI HDD costs three times as much.
The system is working okay but is rebooting when told to shut down. Could you please explain a bit more about the ACPI settings?

Absolutely better to use a PCI-X slot => much better bandwidth.

The WEI # doesn't tell the whole story ... it's largely based on transfer rates.    If the access time is a lot better, then many disk I/O's will be FINISHED with the SCSI drive before they would even start on the Caviar Green.    To confirm that your drive indeed has better access time performance, run a benchmark on both drives using HDTune and see what both the transfer rates and access times are.   http://www.hdtune.com/download.html  [The free version is fine for this]

ACPI settings control the system's response to various power events -- look in the BIOS and see what settings are available to you for this (varies by BIOS), and note what they currently are.     Your reboot issue could be related to an incorrect ACPI setting.

An interesting test:   Boot with a "live" Linux CD/DVD (e.g. Knoppix) and see if the system shuts off correctly when you shut it down.

In the Bios I found:
Suspend Mode---------------------------Auto
Repost Video on S3 Resume------------No
ACPI 2.0 Support------------------------Disabled
ACPI APIC Support----------------------Enabled

APM Configuration
REstore on AC Power Loss-------------Power Off
Power on by RTC Alarm---------------Disabled
Power On by PCI devices--------------Disabled
Poeer on by PS/2 Keyboard-----------Disabled

Are these settings correct?
I do not know where to get a LInux CD/DVD(Knoppix)
This motherboard even supports SAS Drives a better variant of SCSI as it has two Marvel SAS ports.

I have installed a 64 bit Windows Seven in this system it is not 32-bit.

When I changed the motherboard I also upgraded the processor from Core i7 920 to Core i7 960. Core i7 970 the processor which I wanted is not available here and the extreme processor is too costly. Since this motherboard does not have an IDE Cobtroller [nor a floppy Controller] I had to install a SATA DVD Rewriter as well. So a new motherboard, a new processor,a new power supply a new DVD Rewriter has upped the many variables.
Moreover the Windows Seven is on a SCSI Drive instead of a SATA drive an another variable has changed.
In this part of the world there is an acute power loadshedding of the order of 10 hours per day. That will make the developed nations laugh but this is a fact of life here and is going on since the last two decades with loadshedding sometimes less or more. I could not sit on a computer for long and I have four computers and three APC UPS. But these UPS run only for a few minutes so to sustain them I have also installed inverters to run on batteries to give power to the APC UPS for a hour or two hours. So another variable is there.
 Then finally I have a big generator 5.5 KW the final backup of electricity if everytrhing fails but use it rarely because of the noise and as  the inverters are doing their job. Of course they are not much linked to the question but they are variables so I thought you all should know.
It is ten past four n the morning here I will try to download HDTune and Knoppix after some rest/sleep

I have seen this behavior due to SCSI card. To check it you can connect SATA drive with Win 7 directly to mono SATA connector and see if it reboots or not.

Windows Vista is installed also on WD Raptor a SATA Drive and now that is also rebooting. So there is no need of reinstalling Windows Seven on a SATA Drive. If one operating system viz Windows Vista which never rebooted before at pressing the shutdown button is now rebooting is sufficient proof. I disconnected the SCSI Cable from the SCSI Card but still it reboots.
 SCSI card was installed in the previous motherboard P6T Deluxe V2 but no operating system was installed on it but it had no reboot problems.
SCSI Card is also installed on another P6T Deluxe V2 on a PCI-slot and it has three SCSI Drives and there are no reboot problems while shutting down.
Now I will download hdtune & Knoppix and then post the results.

Downloaded the ISO Knoppix but the system still reboots. This is pointing more and more to a hardware error it could be the motherboard itself.

Might be motherboard....but check smps first.


Ded9

smps means power supply.

yes

Ded9

When I got the motherboard I upgraded its  bios from 1107 to 1205. If I remember correctly at the time of installation of the motherboard and for a few days there was no reboot while shutting down. The motherboard might have suffered some damage due to the spikes in the UPS which I later got its batteries replaced and repaired. The power supply Corsair GS800 is post spike dated. It was installed after the spikes took place

I the mob is faulty then u will not be able to install windows..


Ded9

The problem is that I can.

I think u need to check smps or the connectors of power on mobo....connect u r current smps to another computer and then try to shutdown that computer.

Just to clarify -- you downloaded the Knoppix ISO;  made a bootable DVD (or CD);  booted to Knoppix;  and then told it to ShutDown (NOT to restart) ... and the system still restarts -- is that right?

If so, you clearly have a hardware issue.   The first thing I'd do is see if this is related to the SCSI card.    Since Knoppix doesn't need the disk;  turn off the system (obviously);  remove the SCSI card;  and then try Knoppix again.     If the system still reboots, then the soft power command to the PSU is either not being transmitted correctly (a motherboard issue), or you have an issue with the power supply.    If this is the ONLY problem, however, there are a couple workarounds if you don't want to replace hardware that's otherwise working perfectly.    ... we can discuss those after you've confirmed that this isn't related to use of the PCI-X slot.

Removed the SCSI Card, Knoppix 6.2 ISO still reboots the system at shutdown. When it says please remove the CD Drive and hit return. I do not see any return so i press enter or shift and the system reboots. By removing the scsi Card the vga card started to give problems gave scattered and blurry display for a while then after putting the scsi card back it gradually stabilized.
Only once the system did not reboot and shut down properly when I fastened one screw on the scsi card which was formerly fastened by the Cooler Master Casing patented fasteners. I thought I had found the solution but on subsequent shutdowns it again started to reboot. What about the VGA Card it is a venerable 9800 GTX card.

I think what u need to do is disconnect the power cable...hold down the button on front of the computer for one minute to drain flea power...after that disconnect all the cables, memory and the cards in your computer.

Wait for 15 minutes...after that drain flea power....connect all the devices and make sure they are connect properly.

Restart and then shutdown the computer.

Does the system turn off with a forced soft power off (holding the power switch for 5 seconds)?

If so, you can do a "clean" shutdown by shutting down, and holding the power switch when it starts the POST test on the restart.

Doesn't "fix" it -- but lets you use the otherwise-okay system without replacing anything.

The system does turn off with a forced soft power off holding the power switch for some seconds

The soft power working means the chipset CPU (not the main CPU) is working okay -- and is able to send the power-down command okay to the power supply.

This makes it an even-more perplexing problem, as the PSU clearly is responding to power off signalling;  and the motherboard can clearly send it !!

... Makes me wonder if you have a corrupted BIOS.    You're running the latest BIOS ... but I wonder if you had a bad flash -- or if you simply have some corrupted settings.    Does the BIOS have a "fail safe" mode?    If so, try that.

I reverted the bios back made no difference so I again flashed the latest one. As I mentioned the VGA card's display at time flickers[seldomly but it does]. At times it gives a distorted display as if the VGA card is not working but then on restart it works fine.

To check the power supply I will have to go to the shop vendor on Monday where I bought all the stuff from. He has a technician who fitted the board and the power supply. Let us see what he has to say about this.

I had a gut feeling that it is the motherboard. The technician swapped an another power supply with the same result . HE also changed the VGA Card but with the same result. He volunteered himself to sent the motherboard for RMA and I agreed. I am sorry to say that I do not have a good experience of Asus motherboards they may be the largest maker of motherboards but they get wrecked very soon. This motherboard only lasted two weeks. The first motherboard P6T Deluxe V2 could not give a display after some months. Its replacement  again failed to give display after some months. When the first motherboard did not give a display I bought a new P6T Deluxe V2 because that was my main machine I could not wait for the RMA to complete which usually takes a month here.Meanwhile after a month I got its replacement. Instead of disposing it off I made a new system although costly because of the Core i7 Processor and the X58 chipset. Now this system broke and since the motherboard was already replaced under warranty it could not be replaced the second not with the Acer Distributors over here at least. I could not purchase the P6T Deluxe V2 because it was not available the only Asus X58 chipset motherboard available was the P6T WS Professional and the Intel one. THe shopkeeper most probably of marketing reasons aconvinced me to again buy Asus. The intel distributor gives better service because after all it is Intel.

A lot of sages contributed to this page I really do not know how to appportioned the points to close this case.

Not surprising -- as noted earlier, the power supply was clearly responding to a power-off signal since the soft power off (holding the power switch) works.    I agree that Intel boards tend to be VERY stable and reliable -- although they generally lack the configuration options that you get with Asus & Gigabyte boards.
