Random BSOD - urgent

Hi everyone. I've been getting random BSOD and I'm trying to narrow it down to either my laptop motherboard 'which means' dead laptop (manufacture says a replacement motherboard is 400) or just memory. Here's what I've done so far.

I originally thought it might be a software issue. So I took out my old hard drive and put in a brand new one. I tried installing WINXP, but along the way after the first part of formating the drive, where you actually get to the installation part, I got a BSOD.

Suspecting it to be a memory problem, I used MEMTEST to test it out. I don't get consistant results. Sometimes, it finds a fault, sometimes it runs fine for hours on end. I suspect it might actually be the slot where it accepts the memory on the motherboard. Possible? Could I test this memory somewhere else to make sure it is good? Or do I just by another stick and try it out.

Third - could the BSOD be a result of overheating? My laptop does get hot, but I've never had this problem before.

Background information.
I've had my laptop die on me once because of a hard drive failure. I fixed that
BSOD hits up things like PAGE, or some .sys file. I'm not certain.

What is the laptop model.
 Try running ultimate boot cd http://www.ultimatebootcd.com/
 and run the Windows memory diagnostic program. or download it from here http://oca.microsoft.com/en/windiag.asp
As far as heat is concerned, if you have windows up and running you might ant to try mobmeter http://tamaru.homeip.net/~shingo/mobilemeter/mobilemeterreadme-e.htm
or speedfan http://www.almico.com/speedfan.php
to monitor temps.
Do you have more than one memory slots? If you sometimes get errors when running memtest there is something wrong with either the RAM or it's slots, but there is no way to really know which is bad except by testing the modules in another PC and also testing other modules in those slots. If you have more than one slot, try the other, and sometimes, if there is a problem with the slot, you can try reseating the module so that it fits better, or by putting some padding between the module and the cover of the memory bay, so that it gets pressed into place more.

why u think that the problem is from the memory ....as i understand from your Q .. the problem start when u replace your Random BSOD .... so ... why you don't back to u r supplier from where you bay that and ask him support
or try to change other hard drive to make sure where's the problem Exactly

One think I forgot to ask you, what is the stop error you get when it BSOD's?
for the heat : clean all fans and vents, and check if the fans run normally - around 3000 rpm
First you've to determine what type of error it is:


When booting or restarting a notebook using Windows XP without Service Pack 2 installed, the following error message may appear on a blue screen:

STOP 0x000000ED (0xaaaaaaaa,0xbbbbbbbb,0xcccccccc,0xdddddddd) UNMOUNTABLE_BOOT_VOLUME

Notebooks that use Microsoft Windows XP without XP Service Pack 2 installed may start with the following error:

STOP 0x000000ED (0xaaaaaaaa,0xbbbbbbbb,0xcccccccc,0xdddddddd) UNMOUNTABLE_BOOT_VOLUME

This error is related to the way Windows XP interacts with the hard drive during an unexpected shutdown. Sometimes the contents of the cache are not written to the drive properly causing the error to appear when the notebook restarts.

5)Windows Unsafe or Sudden Shutdown
When booting or restarting a notebook, an error message referring to a Windows Unsafe or Sudden Shutdownmay appear on a blue screen.

Windows XP may not start and the following error message may appear on a blue screen:

This error occurs after Windows was not shutdown using a safe method. The notebook may have been truned off without clicking Shut Down or briefly pressing the computers Power button. The power may have been suddenly disconnected from the computer or the Power button may have been held for more than 5 seconds.

An unsafe shutdown can damage some of the Windows system files, preventing the computer from starting properly.

If the error occurs allow the operating system to complete a check of the hard disk. Windows will prompt your to run CHKDSK. CHKDSK scans the hard drive for damaged files and repairs the files if necessary. The scan may take up to an hour depending on the size of the hard drive and the number of damaged files. The computer will restart when the scan is complete and Windows should start normally.

I want to thank everyone for the help. It turns out that the problem was a result of 1)bad memory slot 2)bad memory and 3)corrupt software of winxp. I had ot repeated run the memory tests to find out what was wrong. I had bad memory, but because of the bad slot, I got bad memory for just about every stick I tried, even good sticks from other laptops. This took a long time to work out. But thanks everyone.
You forgot to reward rindi's post, he came up with the bad slot answer.
