Win Xp sp2. Continues to reboot on startup. Cannot access safe mode. Have substituted RAM, power supply, hard drive, disconnected dvd burner and floppy, flashed the bios. No improvement. About to reinstall MB drivers.

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 they could be 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 if this fails to fix the problem
another possible reason could be a memory dump you might be running to many programs at the one time placing to much strain on the CPU also you might not have enough RAM random access memory to check what is running when your computer is running scroll to the bottom toolbar right click select task manager applications and processes if you see something you dont need running select end now to check how much ram you have click start right click on my computer select properties you will see all of your computers details another way to check how much RAM you have click start all programs accessories system tools system imformation all of your computers imformation will be there try uninstalling a few unnecessary programs then click start run type cmd then type chkdsk/r/f which will scan for and attempt to fix any bad sectors and automatically fix any corrupt files on your hard drive this will schedule on a restart don

You got a bad laser in the drive not the laser the reads the laser that writes and this does generally happen when a dvd ram drive goes. Recommend buying a new drive as a replacment laser is upwards of $90 bucks, thanks for using fixya please do accept and rate.

Typically this is a driver issue. See if you can start Windows in "Safe Mode" and look for conflicting drivers. The Windows SDK will help determine the BSOD issue if you copy the information doen. The SDK's are avaialble from Microsoft.

Try booting in safe mode...if you are able to get into safe mode without it rebooting then you have a driver problem, Try updating all drivers and see if that works. If you can't even get into safe mode, then it could be either, Bad RAM, Motherboard, Corrupted Hard drive or power supply.

To trouble shoot Ram, if you have more than one piece, take all out except for one and try it, if it works, then try the other piece of RAM in the same slot, then try both in the other slot, this will tell you if it's your RAM or your RAM slot.

Motherboard, not much you can do

Corrupted Hard disk, try booting into safe mode with command Prompt and run chkdsk utility on your drive

Power supply, make sure the battery is charging, if possible try another battery fully charged for the same model, remove battery and plug laptop in, unplug and just use battery..


Hope some of this helps you

Reboot and keep tapping on F8 to go to Safe Mode. Do not put the reinstallation disk yet. Once in Safe Mode select "last known good configuration".

You can also run "Chkdsk" from the C hard drive Properties if you get to Safe Mode. Double click "My Computer", right click on C drive, select Properties, select Tools tab, go to Error checking and click on "Check now" then check "automatically fix file system errors" and "scan for and attemp recovery for bad sectors" and click "start"

If that doesn't work proceed to do System Restore in Safe Mode or remove previous programs that may have caused your Windows to freeze. If you suspect virus, run your anti-virus in Safe Mode.

If none of the above works then try your XP CD (or reinstallation disk) and do a repair.

Hi,
Try swapping the Jumper block ( Small plastic pin connector ) on The Back Of the DVD Drive. If using both Hard-Drive And DVD Drive on the Same IDE Cable. The DVD Should be set as Master And Hard-Drive As Slave, Or Vice versa.
Failing This, put The Hard Drive On Primary IDE Channel, And DVD On Secondary Channel.
These suggestions, have been made as it appears from your problem listed, that the 2 drives Are Conflicting with each Other.
Finally, is to try a different 4 pin ( Molex ) power cable to either device/Drive. if you have a single rail Power supply unit. the 2 units sharing a joint power cable, may be draining the PSU.

Hope this helps.

Last time this happened to me, I had to reformat and reinstall windows. I tried all those modes, and I even tried the windows repair. None of that worked, I just did a complete new install. All of the data will be lost, if you do this.

My advice, if you need some of the data on that hard drive, you need to hook the drive up to another computer and backup what you need.

Or buy another hard drive, install windows on the new drive. Now slave the old and backup the data.

RIGHT Click...
My Computer
From the menu choose Properties
Click the Advanced tab
Click Startup and Recovery
Under the system failure area take the check OUT of the box that says Automatically Restart.

Windows XP sucks on 128MB, get yourself more memory, go to 1 Gig.
Your problem could also be hardware such as a power supply so re-comment if the suggestion did not work for you.

Try going to Pioneer's website and see if there are any "firmware or driver" updates issued. See if your model is listed. Many problems can simply be solved by making sure your hardware has the current updates. http://www.pioneerelectronics.com/hs/pioneer.html
