Undocumented(?) boot problem sata

I have a strange problem while booting of my sata drive. When i first press the power on button BIOS can't find a valid bootsector if i press reset after this message the computer will boot and give no errors and run without any stability issues. If i need to restart my computer from within Windows XP no error message is given while passing BIOS and no problem occure. I use the promise ID0 which detects my sata drive no problem.
I suspect that the problem lies with the selection of the bootsequeance in the BIOS SETUP. the setting there i use is:
1 floppy or dvd-drive
2 BBS (raid) sata 378... this could be the problem because i don not use raid but there aren't any other boot devices with sata avalible.
i tried using the via controler but that did not use.
any help would be welcom

Sebbie,
Sounds like bios is trying to read disk before it is up to speed. There are settings in disk properties pages to slow down access.
However, if you use boot sequence , Floppy, CD, BB - SATA, enable other boot devices, and enable floppy seek, it may have same effect.

Cold boot problem with X-FI Fata1ty card... Need serious help!

Hey guys:
I just finished upgrading my computer. Realized that I have a cold boot problem. In order to identify the source of problem. I began the following test.
. Remove everything except, cpu, heatsink, ram, video card. Tried to boot with those devices. => No cold boot problem.
2. Install the rest of the ram sticks (I have 4 x 52 in total). => No cold boot problem.
3. Install the other video card (my setup is 7900gtx in SLI) => No cold boot problem.
4. Install the Creative X-FI Fataty card. => COLD BOOT PROBLEM
Once the computer is shut down via the front power switch on the case, the computer will not boot again. To boot the computer, I need to switch off the main power switch on the back of the psu and switch it back on; then turn on the computer via the front power switch on the case. I tried the problem with and without the sound card. Whenever the sound card is installed. There is the problem. If there is no that sound card in my rig, then there won't be any cold-boot problem.
My rig specs:
DFI Lanparty nF4 SLI-DR Venus
AMD Opteron 65 CCBE 609 - Stock speed
4 x 52 MB G.Skill Samsung TCCD LE 2.85V DDR 400
CPU Cooling - Tuniq tower 20
2 x EVGA 7900 GTX Stock - SLI
3 x WD Raptor 74G RAID-0 SATA (-3) 0000 rpm (System)
x Seagate Barracuda 7200.7 60Gb 7200RPM NCQ SATA - 4 (Backup)
Pioneer Black DVR 0 DVD+/-RW - IDE /0
Lian-li PC-V 200B Plus-2 with little case mod
OCZ GameXstream 600W
Creative Fatalty Sound Card w/ Front Panel

I need serious help. This problem is so annoying.
Tnanks and will greatly appreciate it.Message Edited by White_Hair on 0-27-200605:4 PM

The onboard sound is disabled. Unfortunately I sold the Seasonic PSU to my friend. The OCZ GameXStream is suppose to be the higher grade psu than Seasonic PSU. Also, the cold boot problem only exists if the sound card is plugged to the motherboard. I tried change different pci slot. It doesn't seem to help the problem.

K7N2G-ILSR: How to boot from SATA when a raid card is installed

The situation:
1. I have a separate raid controller (Silicon chip) with 2 drives on raid 0.
2. I have another drive (my boot drive) that I want to place on the onboard Promise SATA raid controller.
The problem:
The bios doesn't include an option to specifically boot from SATA, only SCSI. So when I place my boot drive to the onboard Promise SATA raid controller, the system won't boot because it's looking for system files on the raid 0 drive.
Is there a workaround for this?

Well, all my drives are IDE. I did try the SATA RAID using lumberjacker's bios but it isn't stable.
Aside from 3 IDE drives, I also have 2 atapi drives (cdr-w, dvd).
Here's my current setup:
ide 0 - boot drive (master), DVD (slave)
ide 1 - cdr-w (master)
onboard ide (sata controller) - (vacant)
SATA 1 - (vacant)
SATA 2 - (vacant)
promise raid card (2 ide ports)- 2 hard drives on raid 0 (both as master)
What I really want to do is place my boot drive on the SATA port (using a pata to sata converter), or on the onboard promise parallel port. So that it can have it's own port.

Sorry, but another boot problem

I am sorry to ask this question but I have read all of the recent posts on boot problems and followed all instructions but I am still having a problem. It passes the POST then gives the Boot Failure, insert boot disk into drive A message. The only thing I have not done is install a new bios. I have only got one SATA HDD, one CD Writer and floppy.
I have plugged the HD into SATA1 and the CD into IDE1, during the boot sequence it see the CD as Primary Master1 and the HDD as Third IDE Master.
During the POST it passes memory test and can detect both the HDD and CD and floppy.
I have set the HDD settings as follows:
Native Mode
ATA Config= S-ATA only
S-ATA keep enabled = Yes
P-ATA keep enabled = Yes
P-ATA Channel Selection = Both
Combined Mode = S-ATA 1st channel
S-ATA ports definition = P0-1st/P1-2nd
Also I have set the Boot sequence as follows:
1st boot = CD
2nd boot = HDD
3rd boot = floppy
I have built this PC only in the last few days and there is no operating system yet, it has the following specs:
BIOS A6728IMS 3.5 020504
865PE Neo2
Pentium 4 2.40aGhz
2 x 256 Kingston 400Mhz PC3200
128MB Excalibur RADEON 9200 8xAGP
Seagate 80Gb S-ATA HDD
LiteOn 52x CD Writer
PSU: 3.3v 28A, 5v 32A, 12v 16A (350W)
Any help would be greatly appreciated.
Thanks

Thanks, its good to know that I seem to have set it up ok but when I try to boot from the cd (Windows Server 2003) it still says there is a boot failure please insert disk into drive A???

Cpu socket looks strange-can be cause of boot problem?

Actual question: can cpu socket like on attached picture cause boot problems?
tinypic.com/r/1pxnxs/6
(Some pins look strange while I am sure I did not do anything which can cause that)
(Sorry was not able attach pic, so shared on external site - blame android?)
I got problem with booting msi g33m motherboard, I tried various ways and was able to boot couple times, but after reboot the problem returns. When disassembly components for nth time, I noticed strange hole in cpu socket, so I wonder if it can be reason for boot problems? Currently fans run in ÷half speed when nothing connected to mb, if I connect gpu or sata drive, fans are pulsing, and led near power button on tower is blinking, but nothing more happens.

The pin(s) are bent it seems and can be carefully bent back to proper alignment most of the time using tweezers and or tiny jewelers/eyeglass screwdriver.
Yes the problem you describe can definitely be caused by poor pin contact with the pads on the CPU. Depending on what pins are bent or make poor contact there could be many different kinds of problems. In fact many more on newer ones with memory controller and other controllers in the CPU that used to be in the northbridge chip. If you or a friend, family member can't bend pin(s) back into alignment then possibly you could have a local jeweler or watch repair shop do it for you.

K7N2G-ILSR raid boot problem

Hi,
I have an msi K7N2G-ILSR mobo and am having boot problems on the raid system.
Everything worked fine (raid 0 set up sata) and would boot fine, the bios had to be set up to look for other boot devices in order for the system to boot with raid drives.
Problem occurred when I added an ide card to give me 2 more ide channels. Still fine if I only connect cd roms to new card but as soon as I connect a hard drive it appears the msi board stops looking for the raid drives as a boot device, because I get the message NIVIDIA Boot Agen PXE-2.0(build 082 v1.82)
Copyright......................(info)
Copyright......................(info)
CLIENT MAC ADDR 00 10 DC E1 4C AD GUID:
FFFFFFFFFF..-FFF..-FFFFFF... etc.
PXE-53: No boot filename received.
PXE-MOF: Exiting NVIDIA Boot Agent
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
It seams there needs to be a bios update as when you scroll through boot options (first, second & third) in advanced setup there is no choice for raid. Therefore the only way to boot from raid is to choose “look for other boot devices” and that is OK until you add a second ide card with hard drive on.
I have version 1.6 bios (latest on msi`s site)
Any idears on how to get round this ?

Hi Raven,
For your info windows xp will support any number of ide channels (upto the number of spare pci slots you have).
I have another computer that has 2 extra ide cards in and has 2 dvd`s (on seprate channels) & 6 hard drives as well as raid hard drive set up. Windows is not confused and supports all devices and has done for the last few months ! This mobo has boot from raid in its bios so has no problems on boot up. The reason I need so many ide channels is simply I do video work and need loads of storage space so until I can buy 800gb hard drives for a reasnable price I am stuck with having to buy 200gb drives.
As I said it looks like either a bios update from msi or I`m going to have to buy a new mobo.
Regards.

Z87-GD65 boot problems

Hello, my pc has trouble booting up, whenever it starts it runs for about 2-3 seconds and turns off and goes into a boot-loop. However i have found a way to work my way around this by pressing the power button longer (during the boot problem) and after that it boots up just fine. What do you guys think that is wrong with it? Whenever it has been running and i restart the pc it boots without problem. It is only there when i boot up in the morning when the PC has been turned off for a while

Kind of indicates a power problem. Recommend you try it with a fan running directly off the PSU. A HDD is not what I am trying to convey here. If you have any sleep or hibernate features enabled, the fan connected directly may be the key to it starting when you hit the button normal.
RAM test is still a good idea though.

P45 Platinum boot problem!!!

PC specs in signature below!!
Ok, this is a new system, and it has been running GREAT since I started it for the first time. I am running my RAM with manual settings of 5 5 5 18/1.8v/800. Nothing is overclocked!!
Anyway, this morning I get to the office anxiously anticipating starting up my new system for a day of pristine computing. It starts up, the screen appears where you can hit "delete" to enter the bios. The screen hangs there for allot longer than I remember. Then, I get this message popping up on the screen: ''Reboot and select proper boot device or insert boot media in selected boot device''.
The first thing I did was hit Ctrl/Alt/Del to reboot and enter the bios to check my boot order. Everything was set exactly the way it is supposed to be. CD/RW first, then my OS drive. I exit out, and it boots into windows just fine.
Ok, later I decide to run check disk on my OS drive, thinking that maybe it's going bad, and the bios is having trouble seeing it. Check disk finishes, and it goes to boot into windows, and I get the ''Reboot and select proper boot device or insert boot media in selected boot device'' message again.
So, once again I hit Ctrl/Alt/Del to reboot, and it hangs on the screen where you can enter the bios. I quickly hit delete this time to enter the bios to see if my operating system drive is recognized. When I do this, it enters the bios, but hangs for awhile where it detects the hardware. Finally I can get to all the features in the bios, so I check to see if my hardware is recognized. Both my SATA hard drives do not show up as being recognized. My SATA CD/RW shows up, but not my hard drives.
So, I exit out of the bios, and it boots to windows just fine. I restart my system again to see what happens, and it boot just fine into windows.
Anyway, I went ahead and shut down my system, pulled the power plug, and cleared the CMOS. I then started the system back, entered the bios and set up all my settings, and it boots right into windows fine.
What do you think happened here? At first I thought maybe my OS drive was going bad, but after discovering that the bios didn't see either one of my drives, I ruled that out. Plus check disk was fine on the OS drive.
Any ideas??

Ok, I am still having an issue with this boot problem described above. Now that I have used my system allot more, I have discovered some more details. This boot problem only occurs when I plug anything into the system that gets noticed in the "boot order" in the bios. Example: USB thumb drive, external hard drive, or even swapping out an internal drive. The next time I re-boot, it fails like I described above.
Ok, here are some more experiences I have had. My system had been running great, and boot ups were working perfect. I decided I wanted to add a 3rd internal hard drive for storage. I already had my C operating system drive, and a D storage drive. I bought a large Seagate for a 3rd F storage drive. My CD/RW is listed as my E drive. So, I power my system off, and turn off the switch on the back of the PSU. I then add my 3rd hard drive and hook it all up. I power on my system. It boots to the bios screen where you hit delete to enter the bios. I enter the bios and I see all three of my hard drives. I check to make sure my boot order is correct, and save and exit the bios. As it booting, this time it hangs for a longer time at the screen where you can enter the bios. I hit the delete key to enter the bios, but it once again hangs while it tries to list all the hardware. Finally I can get to the bios setup screen, and both my C drive and D drive are not recognized, but my new Seagate is. For the record, my C drive is connected on the #1 SATA connection, my D drive is on the #2 SATA connection, and my new Seagate drive is on the #3 SATA connection. So, I select optimized defaults, save, and exit the bios. I re-enter the bios just fine and in the normal timely fashion. Now all my hardware is recognized. I set up my RAM again and other settings, and save, exit, and my system boots perfect.
So, I go about a week of perfect boot ups and no problems. I decided to buy a new larger hard drive to replace my existing C operating system drive. My plan was to install the new drive, and simply restore from a current image made from my old hard drive. I get my new C drive installed, and plugged into the #1 SATA connection on the mobo just like before. Ok, same drill......I enter the bios, and all my drives are recognized. I set my boot order, save, and exit. AGAIN, when it gets to the bios screen where you hit delete to enter the bios.....it hangs for longer than usual. I know exactly what it's doing, so I hit delete. It lags again as it starts to list hardware. Again, when I get to the setup bios screen, my C drive, and D drive are not recognized, yet my F drive is......just like before. So, both the drives connected to the #1, and #2 SATA connections on the mobo are not seen in the bios, yet the hard drive on #3 is seen. I do the same thing again, which is load optimized defaults, save, exit, and re-enter the bios again just fine. All drives are seen, I set up my personal settings, and all is well again.
The last time it happened was when I connected my USB thumb drive. Same exact scenario. The thumb drive shows up, and my F drive with the C drive and D drive missing again.
Any ideas?? The system will run just great now the way it is. But, the second I stick my thumb drive in, or an external hard drive, my C and D drive will disappear on next boot. If I kept the thumb drive and external drive connected, and just loaded optimized defaults, then rebooted and loaded my personal setting, I would never have the boot problem again. It just doesn't like me disconnecting, and re-connecting hardware I guess.
About the only thing I can think of to try is connecting my C and D drive to different SATA connections. But, even if that worked, it wouldn't fix the problem.

K8N Neo2 Windows XP Boot problems

I've recently built a new machine based on the K8N Neo 2 & Athlon 64 3500 and am having intermittant problems during boot into Windows XP.
Basically the machine seems to hang just as it gets to the 'Windows XP' logo. The screen looks blank, but if you look very carefully the logo is displayed very faintly. I have tried connecting the startup disk to both SATA1 and SATA3 with the same results as at first I thought it may be some kind of driver problem. I didn't have to install any SATA drivers during the XP install which surprised me.
I have also run Memtest86 on the two sticks of 512Mb PC3200 Geil Ram which seemed to test OK.
Once running the machine is stable, its just annoying that it may take 2 or 3 tries to get it up and running.
Any help or suggestions would be very much appreciated.
The full spec of the machine is as follows:
K8N Neo 2
Athlon 64 3500
Geil Value PC3200 512Mb x2
Maxtor Diamond Max 9 80Gb (Boot Disk)
Maxtor Diamond Max 10 200Gb
Sapphire ATI Radeon 9600XT

I will not install the nForce IDE drivers on the (I guess soon) reinstall. I've read that the PS/2 keyboard also could be the badguy in this weird boot problem but I cant understand why and how the keyboard could add time to the bootup sequence only sometimes, I guess that it has something to do with the XP keyboard driver ??..
Anyone with any other tips is welcome. Other than this weird problem my system runs perfect. MSI Core Center now tells me that my CPU temp is 45% (CPU speed 1004) (Downloading stuff but not doing anything else), CPU speed is according to XP 1.79Ghz and I use the Cool 'n' Quiet function, On what temp should I start to become alarmed and is there some way to setup something in the bios to shut down or warn me when and if the CPU gets to hot ?..
Thanks for helping a new MSI user out

Report: K8N Neo3-F Cool boot problem!!!!

Hi all,
I've got Cool boot problem on my new K8N Neo3-F. The power is often turned off suddenly just after I turned on the power switch. All components are shutted down while the power led blink. It's unable to turn off completely by pushing power switch for awhile. I usualy have to disconect the power cord then clear cmos and cool boot again.
This problem seem to occur more oftenly when using SATA HDD. Should it be attituted to a bug bios?

Something along what you already have on +3.3v/+5v but 20A or more on +12v (single +12v PSU model) .
But when the time comes to replace PSU it's wise to get one that has enough power that will serve the next build or upgrade also .
Not leaving you again in the same situation you are now one more time down the line .
Note that HD's are notirious power eaters .They all may have nice numbers from the manufacturers for write/read consumption
but it's not many that specifies spinup consumption which always are altleast 2-3 times the amount of read/write power demands.
Tagan 2power/2force is nice and is applicable to both 20/24 pins systems and has the ability to run the +12v line as one combined or dual .
They also come in different sizes (max wattage) .

K7N2 Delta-L: Strange cold boot problem & solution

My K7N2 Delta-L has a problem cold booting when the vcore is set in the bios at 1.65v of higher. After a cold boot, you get a blank black screen. I noticed that even if you run at default speeds but set the vcore to 1.65v of higher the problem still occurs. There is no problem rebooting however.
I found the following solutions:
1. After you power up and get a blank, hit the reset button.
2. Don't unplug your PC. My PC is connected to a AVR and after I power down the PC I usually turn the AVR off. If i do this, than the computer will have a booting problem if I try to boot it up 30 minutes later or so. Now if I don't unplug it/power off the AVR than everything is fine.
I don't understand why it acts the way it does though.
Does anyone know of any other solutions?

Have you cleared the cmos. If you do be sure you have the power turned off don't move the cmos jumper with the power on.
I found that turning off power at power supply and unpluging, than turning on the computer the fans will spin just a little this drains all the power. Clear cmos 2-3 than return to
1-2 position.
Than plug the power back in and turn it back on, than try the computer again.

Mid 2006 iMac Boot Problem (Since latest firmware update)

I have a Mid 2006 17" iMac. Ever since the latest firmware update in early December, about every other startup I've been having boot problems. After the white screen with the Apple Logo and the spinning wheel it goes to a blue screen like normal, but instead of the 'Loading Mac OS X' white window popping up it stays blue and the spinning loading wheel starts. I've left it loading for quite a while before and nothing changes. I have to do a force shut off by holding the power button. and then I start it up and it will boot normally.
Any help would be appreciated.
Thanks!

Actually, I think it'san early 2006.

1st series iMac G5: Booting problems, kernel panics, waking from sleep...

Specifications of the iMac described: 1.8 Ghz, 1GB, 80GB, 64 Mb Nvidia VRAM, Airport, 10.5.5
Back in August 2004 my dad bought us kids an iMac G5 for ‘family use’. It had a fresh install of 10.3.5 on it and compared to the (1999) iMac G3 it replaced it was amazingly fast.
The iMac never showed any signs of probable issues, until we decided to upgrade to Leopard in January 2008. Initially, this upgrade was only meant to be able to sync with the latest iPod nano (who demanded a newer version of iTunes).
After the installation the first thing I noticed was a high CPU usage, the machine seemed slower than ever and that with 1 Gb of RAM (the minimum sys. req. for Leopard are 512 Mb of RAM). Anyway, then the real thing started, it wouldn’t turn on anymore. We brought it to an Authorized Apple Reseller, the Tech department said the Logic board had failed. The costs of the fix weren’t the worth the computer anymore, so...end of story. The iMac was indeed one of the bad series, although it hadn’t any swollen capacitors.
My dad already made up his mind and bought himself a Macbook. He then told me that if I was able to get the broken iMac fixed, I could keep it. And so, I bought an ‘as-is’ logic board on Ebay. Last weekend I installed it, and it actually seemed to work! Yet, the problems are during the startup: the first thing I see is a screen full with horizontal lines flickering all the time, like an old TV with bad signal. Mostly it won’t boot and I get the message to restart the computer (kernel panic, I got dozens of logs already!). Sometimes it got stuck during booting (grey apple screen with gear in the middle) making the fans go crazy (after a while) and sounding what others describe as a ‘jetliner taking off’ sound. Sometimes the screen remains black. Generally it takes me 5 to 10 minutes to start up properly. Maybe it’s just me but it seems like when the computer has warmed up a little (by turning on and off on and on) starting up gets smoother. I mean the startup screen suffers from less horizontal flickering lines.
During the use of Leopard, I again get high CPU usage, especially when I use multiple programs at the same time, or when starting multiple programs. My iStat Pro said once that the fans were running at 4700 rpm and the heat of the CPU was about 70 Celsius. If I really want to **** my iMac off I should play a racing game. That just totally freaks him out! These problems could probably be solved by adding more RAM. Right?
The iMac also has a sleep problem. Sometimes after lets say an hour or so, you can’t get it out of sleep mode (by manipulating keyboard and/or mouse, the sleep light stops, but the screen stays off --> only solution is to restart). What happened to me once was that it slept so long that it just got into a deep sleep by turning itself off completely!
Here’s a list of what I tried so far:
- Disk Utility: Resetting the permissions, no problems were found.
- Resetting the SMU, both on the logic board itself as by pressing the power button 5 - 8 seconds, no improvements.
- Resetting the PRAM, no improvements.
- Did the Hardware test of the original install CD, nothing was found, all good.
- Did Archive and Instal, this actually messed my system entirely, cause it wouldn't boot at all and when starting up from the Leopard installation DVD it wouldn't recognize the Macintosh HD.
- Did Archive and Instal with the original disks, this disk did recognize Macintosh HD and so I installed the original system, 10.3. Booting problems and those flickering lines are still there though.
Next phase will be erase and install, but first I want to know what you guys think about all this.
Oh eh, One more thing; The guys at Applecare (phone support) told me that the replaced logic board was also out of warranty and so they couldn’t help me. But as the man on the phone was kind, he told me to go look for a special ‘driver’ on the net. He said that the driver should be able to resolve some of the issues described. He said that I had to give in the name of the LB on google and look for results. Is this bogus? Because I haven’t found anything useful on google so far. What’s the name (rather than a number) of the LB in the first place?
I hope you guys can give me some answers. I'm kinda desperate. But I still feel there's hope...

The symptoms of a flakey power supply are sleep problems and you have done all the right things as far as resetting the SMU and PRAM. Your CPU usage can be tracked by going to Utilities>Activity Monitor - look and see what is hogging the memory. The flickering lines could also be an optical system going south.
The other thing you can do is run DiskWarrior or TechToolPro to see if you have corrupted directories. Preferential Treatment will let you check for corrupted preferences.

*Soundcard: Soundblaster Audigy
OS: Windows XP home, service pack 2
*Lite-on IT dvd-rom drive
*floppy disk drive
I also have 3 case fans spinning away in a marginally large Chieftec Dragon tower.
The parts I marked with an asterisk (*) are parts that I removed from my old rig and re-used.
I'll try to give a clear rundown of my problem and the steps I've taken so far.
3 days ago I acquired the P45 Neo and installed it into my system, together with the 8800GT videocard. I was still using my old PSU, a Chieftec 360watt. This PSU served me well for 7 years, but it was starting to build up noise while trying to keep up games on my old rig.
I had some trouble getting the system to boot, I tried changing some of the 4 pins wires going to the hard drive and the dvd drive. I don't know if it was luck or if I managed to divide the load properly for the system to boot. But I succeeded into booting up, got into the bios and eventually installed WinXP.
As soon as it was time to install the videocard drivers, it stopped responding. I assumed it was a power issue, since I could only install the 20pin and 4pin cpu, but my Chieftec PSU didn't have a 24pin plug to the mobo - and it needed replacing anyway! So I bought a new 500watt PSU that had all the required plugs and more wattage.
I installed the new PSU, checked every connection and pressed the power button. 'Lo and behold, the computer starts up. I install the videocard drivers and it proceeds with no problems. I try to install the soundcard, but the cd says I don't have one installed. I fix that by going to the System list and install the drivers from there. I install a firewall. By then I have successfully rebooted the computer 3 or 4 times. I decide all is well and turn off the computer. But I realize I wanted to check up something on the internet.
I press the powerbutton. The PC power light go up for just a fraction of a second. I can see the blue LED of one of the case fans switching on just as briefly - then it goes out. The computer keeps trying to turn itself on. It looks like it's hickupping to try and boot!
I turn off the PSU power on the back-side because the computer keeps trying and wait for a bit. After 10 minutes, it still doesn't work. I leave the computer for a bit and return an hour later. The computer then starts up with no problems. I turn it off after a few hours, do a reset, start it up, no problems. But then the next day it happens again.
It's pretty tough figuring out what the problem is because it looks..almost random. I considered it could be a heat issue, but sometimes it *does* start up just after it's been turned down. Checking the bios shows no strange temperature shifts.
Hope anyone can help me, because I do not want to go back to my old Asrock mobo

While powered down I cleared the cmos data, removed the Dane Elec DDR2 module and set the bios to optimized defaults. Computer restarted to WinXP with no problems (it has been off the whole night). I shut down WinXP, wait a few moments and then turn the computer back on. Alas, it won't start and starts hick-upping. I turn power off at the PSU again, so it stops.
Now I try switching out the Kingston module instead. By now the computer has been off for 10 min (while I write this entry on laptop). I press the power button on the PSU and then the power button on the front. There is a short pause, lasting a second. The computer turns on, longer now, but it only lasts 2 whole seconds before it turns off again and goes on again (I believe now you can call it powercycling). It repeats this process until I shut off the PSU.
I check to see if I have installed it properly and try again but it starts powercycling again.
15 min pass, I put the Kingston module back in, press the power button and voila, this time it does start. WinXP shows up, no problems. I leave it on for a bit and then shut down. And when I press the power button again - the feeling of dread returns, when it starts hickupping again.
I'm going to see if I can install one of the memory modules from my housemate. Then hopefully tommorrow, I'm going to try if I can test a different PSU, since I see someone else on the forum - who recently posted, has the exact same power supply and also has boot problems, coincidence... or not ^^;.

I have an early 2008 Mac Pro, which has re-booting problems. Also what does the spinning beach-ball indicate?

Hi, I have an early 2008 Mac Pro which has re-booting problems.
Processor speed is: 2.8
Memory: 2GB 800 MHz DDR2 FB-DIMM
2 x 28GHz Quad Core Intel Xeon
I am running OSX Yosemite Version 10.10
My Mac Pro keeps re-booting. Last year I had to replace my graphics card. My original card was the ATI Radeon HD 2600 XT 255MB, and that is what I have now. At this precise moment my Mac Pro is running perfectly, except that it is slow and the spinning beach-ball keeps appearing. I have managed to do some work with the disk utilities, verifying, cleaning and partitioning. Some errors were found and when it was cleaned this seemed to help my Mac Pro to function properly. Although I am able to use my Mac Pro now, from day to day I still experience re-boot problems. Also quite unexpectedly my mac dictionary has an error, it closed itself down and will not open at all, I had the message to say that a report will be sent to Apple.
I have tried starting my computer with an external hard drive fitted via a USB cable, I use for back-ups. This worked and I was able to wipe my hard drive clear and replace all info from the back up I had done only a few days ago.
This worked for a few days and then the same problem started again.
I am beginning to wonder if I need to buy a new hard drive.
If there is anyone who has some answers to help me solve my problem, I would be most grateful.
Robert

When you have the beachball activity, note the exact time: hour, minute, second.
