Laptop stuck in starting loop

Hi:

My wife's laptop started acting funky today. When we start it up it will display the MS Windows XP screen like it is trying to load it up as usual. Then it will make a ugly noise, flash up a blue screen with an error message and restart the machine. Sometimes, it will just keep looping through this cycle. Then for some reason it will actually load up XP and it operates normally. I would guess 1 out of every 5 restarts it works. Then other times it will take us to a page with options to start in various safe modes, under the last windows config or just a normal startup.

I was to finally capture the error: 0x0000000A: IRQL_NOT_LESS_OR_EQUAL

A recent send error report a couple of weeks ago indicated something to the fact of 'Intel Pro/Wireless Lan 2100 3B Mini PCI Adapter w70n51.sys' needed updating from dell. I download a driver from dell and it still returned the error.

I went into the setup at the startup and disable 'MiniPCI Status' and turned off 'Wireless' and rebooted. I was able to login at will without any errors or stuck in a reboot loop. Of course, I don't get any internet access without it. But, we can access her files for backup.

At this point, I'm thinking of reinstalling everything. Of course, she doesn't have any of the original disks. Would a reinstall resolve this issue? Or is there another route I should take with that error? I'm at a loss at this point.

Here is her system info:

Dell Inspiron 600m
Windows XP SP2
30 gig hard drive
500M memory.

Thanks!
Shawn

 

I gave that a try and it bombed out. The error message change a little bit:
It still says IRWL_NOT_LESS_OR_EQUAL

But this part is different:

Stop: 0X0000000A (0xF8958200, 0x00000002, 0x00000001, 0x804D9BBA)
