Re: Intermittent Reboots

I would first remove some RAM to see if the problem persists. It's an easy beginning to get your problem resolved.

P55-GD85 - after power up it pc reboots 5- 10 times till its working fine...

Hello my guess is you have a overheating problem.
Try to remove the cpu heatsink and clean it for old cooling paste
then apply new paste.
BE CAREFULL not to damage the cpu if you not are familiar with that ask someone who know how this has to be done.

You could also have a nasty trojan/virus on your system

And remew/update your antivirus program.

I have a mobo Asus P5KPL AM Se, 1gb ddr2, intel dual core Processor. The system will turn on a ccouple og minutes then it will automatically restarts. Even when i enter the bios, after a couple of seconds...

you may have a problem with your heatsink on either the processor or the north brige chipset. if either of these are overheating this would be your symptom. I would disconnect all items (including sound and usb connections and drives) except for power supply and front panel connector. in the bios you can under apm configuration/hardware monitor to check this ( so as to isolate the motherboard and powersupply and video(video usually cause reboots but it takes 10 to 20 minutes for it to get that hot).
if this still happens I would then suspect your powersupply (although rare for this type of failure) and try another one.
hope this helps

Pc reboots at "starting windows"

im not sure what this isn't you are refering to i come from the old school of english

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps

Computer doesn't boot after a couple of reboots

Have you checked the backup battery to the Bios. You should have one that charges when its on and one that is more like a large watch battery that keeps the Bios memory when no power is available. If these are not the problem, then you may have to do a Bios flash from a disk from manufacturers web site.

If you have no power at all, then double check power supply with voltmeter.

Continuously reboots

Hi there
First you will need to boot up. When you do this you need to go into bios and then go to boot and disable the hard drive floppy and any other drivers. You must make sure you keep the cd driver as 'able', save setting and exit out of bios. This will let you reboot. After it`s done, the partition in the computer will reboot the computer. Make sure to go back into bios and able the hard drive, floppy etc...
I had the same problem, and solved it this way.

Boot up problem

Sounds as if you need to change your cmos battery (Cr2032 on motherboard) first of all as i'ts a very cheap item to replace, then set the bios up again, then try to boot, if still no boot you may need an operating system repair.

BIOS intermittently loses CDROM

Hi, first check that your RAM chips are seated firmly, then check the CPU fan for dust, then if you still have the problem try disconnecting the on/off switch wires that run from the case to the board, bridge the two pin out to mstart the computer and see if problem still exists. The final test I can offer is the power supply, If you can use a multimeter and test the voltage. Yellow =12v red=5v black=ground. If you get a variance of more than 2v replace the unit. Another way is to try a diferent power supply. Regards mistyman
