|"uncheck automatically restart and then post the exact error that comes up when it bluescreens, that will surely help."|
Win XP is set by default to automatically reboot when it encounters an unrecoverable error.
To have XP possibly display an error message you can investigate instead of the computer rebooting:
1. Click Start, and then right-click My Computer.
2. Click Properties.
3. Click the Advanced tab, and then click Settings under Startup and Recovery.
4. Under System failure, click on the small box beside Automatically restart to remove the checkmark.
5. Click OK, and then click OK.
If you then get an error message, look at all of it's details.
Sometimes you either can't get Windows to work properly long enough for you to be able to do that.
In that case,
- remove any bootable disks you have in optical drives
- press F8 repeatedly while booting, don't hold down the key, and select
Disable automatic restart on system failure.
Windows will then attempt to boot normally, and you may then get a message on a blue screen sooner or later, instead of it auto restarting. .
- that only disables automatic restart when you boot using F8 and select that. You must disable it under Startup and Recovery if you want Windows to always do that.
What we need to be informed of on a blue screen ....
any STOP 0x000000xx message (the stuff in brackets after that is usually useless to us)
any TEXT_MESSAGE_IN_CAPITALS_WITH_ UNDERLINES_BETWEEN
A problem file may be named, often at the end of the text - tell us what that is.
There may be a link to more info, or similar - if so, click on the link to see if a file is named.
If you don't get a message, or if you still get the boot loop.......
- Contrary to popular belief, it is extremely rare for ram that was working fine previously to suddenly go "BAD".
However, it's common for the ram to develop a poor connection in it's slot(s) over time.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.
If you do a ram test, do that AFTER having tried cleaning the contacts and making sure the ram is seated properly - otherwise any errors found may be FALSE.
Memtest86 has bugs that can produce FALSE errors in some of it's tests if your mboard has an AMD cpu. Version 3.5 has bugs that prevents testing when you have more than 4gb of ram installed - use version 3.4 or lower if more than 4gb is installed.
If you want to try a memory diagnostic utility that takes a lot less time to run a full pass than memtest86 does, this one is pretty good - Microsoft's
Windows Memory Diagnostic:
Windows Memory Diagnostic is limited to testing only the first 4 gigabytes (GB) of RAM.
It can be toggled (press T) to do a standard or a more comprehensive set of tests - use the default 6 test one first - if it passes one pass of that, use the latter one. A few of the tests in the latter set are intentionally slower.
If you don't have a floppy drive, see the Quick Start Information at that Microsoft link for how to make a bootable CD of the Windows Memory Diagnostic (you need Windiag.iso - you don't necessarily need to use the program they mention to add it to the CD).
- if this is a desktop computer.......
Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.
Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .
This was the original bad capacitor problem - has some example pictures.
History of why the exploding capacitors and which mboard makers were affected:
What to look for, mboard symptoms, example pictures:

- what the problem is caused by
- he says there are STILL bad capacitors on more recent mboards.
Pictures of blown capacitors, other components, power supplies, Athlon cpu's, etc.:
- faulty or inadequate power supplies can also cause boot looping, and they can also have bad capacitors.
Inadequate = there are lots of people these days who have installed a video card in a slot on a desktop computer that has a video chipset that requires a higher minumum power supply capacity than the existing power supply has. The video card may work anyway at first, but eventually the power supply is damaged from being constantly overloaded.
