Could it be a battery failure?\n\nWhen the computer finally boots, it sometimes restarts itself 2 minutes after booting. But after that, if all goes well, my comp is able to keep operating smoothly for a log time as long as I do not restart or switch off the computer. What's up with my comp?

Something in the power supply is not right, your power cable may be loose, cabling may be an issue, your SMPS may be an issue. You need to get support from a hardware technician

I like the response kanis gave..just had one thought to add...a possible hardware problem...have seen a lot of pc's that start randomly shutting down when the mainboard has swollen or burst capacitors on it..you may want to check for that when you take the side of the case off and get in there to dust fans etc

This definately sounds like a heat problem. CPU overheats and the box automatically shuts down to keep it from burning out. If the CPU is still too hot that would also prevent you from restarting right away. It could also be the power suplly, but I don't know of any that have a connector so the motherboard con monitor it's heat. They may monitor themselves though, not sure. Next time you start it up, go into your bios and find a setting named something like "PC health" or "hardware monitor" depending on the bios version, and it should tell you there what the temp of your CPU is. Watch it for a while and see how hot it gets. How much heat a CPU can take depends on it's model, but around 70c is edging towards dangerously hot. If this is the case, you'll either need a new CPU fan, or the CPU fan is installed incorrectly. If you do need to replace it, or reseat it, do NOT forget to put thermal grease between the CPU and fan. It's an easy mistake to make if you're a begginer and it will fry your CPU. Either way, good luck to you.

You may have a stuck key, check your keyboard or a card half unplugged or your cmos battery is dieing.....or just about dead...if the computer does not run or load programs, then it could be screen or Memory is wrong or not plugged all the way in...

are you getting power or not. i would first check all the cables to see if anything are loose. i would also check the power supply. and also would look in you motherboard book to find how to reset the bios.

Check to make sure you dont have any recalls on that particular thing. Maybe you didn't put it in correctly. ummm maybe your laptop is not responding correctly to it because the unknown error is not effecting it. Just follow the error and keep doing what ya doing. have a nice day

it should reboot into "normal" mode when you reboot.  It may have a problem still and not want to boot normally.\nIf you press the F8 key when it is booting you should have an option to start normally.\n\nIt can also be set in msconfig. Someone may have set it for safeboot\nsee the symatec link

need more info than that to diagnose.  make sure your cables are plugged in tightly?  is the jumpers on the hard drive on the correct pins?  can you hear it booting up. when does it stop?\ntoo many variables

You can try to go to your computers BIOS setup and check to see if your hard drive is set properly, it should be set on "Auto" and it should be set to be the boot drive....This should have been the first thing the people that tried to fix it checked...

There are several reasons for this thing to happen.\nWhat I have normally seen and diagnosed. will tell you about those points below.\n\n1] IF at all you have a CD-Rom Drive which is faulty. i.e. does not eject properly or even does not read CD's properly. This cd-rom can create a problem while booting. The computer will try to acces the CD-ROM if you have chosen 1st boot Device as CD-ROM and while it tries access it and the CD-Rom does not respond. The computer in return goes into a hang state. At this time same screen appears which you see.\n2] Tell me DId u remove the Hard DIsk Cable. If yes you would have plugged in wrong back. the Blue or the red line which appears on the one end of the cable should be next to the power connector on the Hard Disk or where ever its mentioned that its the 1st pin the the connector. Again same applies towards the Mother Board connector Blue/Red line should be plugged in where it says 1 [i.e. 1st pin of the connector] If at all the Hard Disk Cable is plugged in wrongly display appears to fail. or try pressing the cable properly inside the slot this might also help.\n3] Try booting with a Windows XP Bootable/installable CD and try repairing the installation. This will be the best solution for you. The option to repair should be the second one which appears while installation.\n\nLet me know if this helps you.

take your laptop to the service center as this should not happend maybe the battries arnt proper or maybe theres a problem with the laptop itself

Really could use more info like brand of computer, what OS is being used, if computer is laptop or desktop, what is actually showing on the screen "after it turns back on", does it prompt for the login password, etc.  For example, if it's a laptop, when the lid is closed a switch is activated. The lid might have a small nub that fits into a small slot that contains the switch. Or the lid might press down on a small pin. Sometimes that switch gets stuck, won't release, and the machine thinks it's still in standby. You'd need to check for that switch and make sure it's not stuck. Other problems could occur with a desktop. \n\nYou can always try a forced shutdown.  Press the CPU power button and continue to hold it for at least 30 seconds.  After you release the power button, wait another minute before trying to restart the computer. This give the hard drive a chance to stop spinning completely. Try restarting.  You might get an error message or warning that the computer was not shut down properly the last time and ask if you want to perform a check disk operation. Say yes.  Hope this helps.  If not, more info please.\n\nplrr

Maybe the computer went into power conservation mode. Try pressing the power button.

It sounds like it is staying in Standby Mode.\nRight Click Desktop> Screen Saver> Power>   System Stanby and Hibernates to (NEVER).\n\nGo to to system Setup. Restart your system and press F2.\nand set power Management.\nHarry

well man its a complex matter.first of all remove the ram chip form the computer then turn on the computer. the screen will be blank after some time place the ram in its slot and plug on the comp.it will boot. else do the same with the cell(semose battery) & then both of them.if it still does not work then please send me an email.

Restarting of computer on its own can be due to:\n1. Loose RAM, just insert it again in the slot...\n2. Capacitor on motherboard is burnt...get it repaired\n3. any virus which affect the boot area.... clean it

the problem is not a bad pcb board, it is the firmware, here is a site with suggestions that have worked for other people\nhttp://forums.onforce.com/viewtopic.php?p=30550, thewy say someitmes just leaving it on for a few hours running might reset the firmware\nlooks like the only other alternative is to send it get datarecovery and repair, or get the bios and repair kit for 400.00 from china\nsorry
