T61 Blue Screen

Question

If it doesn't rain it pours. 6 months with no issue and now three in a week. I was performing a scan with AVG 8.5 when the laptop blue screened. The error was
stop 0x000000024 (0x001902FE,0xBA51F8F4,OXBA51F5F0,0XB9D7FB7F)
AT B9D26000,Datestamp 48025be5
I really am scarred of doing anything else with the laptop. I have all my work on it and although the advise was to perform a chkdsk /f on the hard drive I wanted to check what the problem might be based on the error message before I did anything. My information is too valuable. So I guess a complete back up may be required first. If I do this first can you advise what next based on the error message. Thanks.

Hi flambo,
Welcome to the Lenovo forum 
Sorry to hear about the trouble you're having.
Your instinct is correct, you should definitely back up your data! I'll recommend backing up to a 2.5" external USB hard drive, if you don't already have one. Your personal data are by far the most important stuff to back up, you can simply drag-copy them over from your ThinkPad's hard drive to the external drive. After that, you could also back up your entire system by using Rescue and Recovery, although I prefer Acronis True Image for the task (faster). To each their own, both will work.
As you've probably been told a thousand times, it's important to back up your data regularly, all the time. You're probably more a believer now that you're having problems 
Anyway: *after* you've backed up your data, then it's time to try to figure out what's causing your blue screens. Have you changed anything recently? Added RAM? Installed new software? The latest change is your first suspect.
If nothing jumps out at you (or even if it does), I'd recommend starting by running some hardware diagnostics. You can download the PC Doctor boot CD from the Lenovo support site. Boot that and run all the tests. For a more thorough check of your RAM, you can boot the memtest86+ CD and let the tests run through at least one complete cycle, or even overnight. If everything passes so far, you can check your hard drive by running the "extended tests" of the hard drive utility from your drive manufacturer. The various utilities are conveniently collected on a single CD: Ultimate Boot CD. 
If all of the above tests pass, you can be pretty sure that your hardware is OK, and that you have a software problem. Go ahead a run the chkdsk as suggested, to fix any errors in your filesystem. And then start looking more carefully at any software updates you've recently applied.
Good luck! Please let us know how it goes...
