Stop Error (BSoD) BCCode: 77, 10000050; Hotfix error

[RGBRGB]

Lenovo ThinkPad T61. T7500(2.2GHz), 2GB RAM, 160GB 5400rpm HD, 14.1in 1400x1050 LCD, 128MB nVIDIA Quadro NVS 140M, CDRW/DVDRW, Intel 802.11agn wireless, Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure chip, Fingerprint reader, 6c Li-Ion, WinXP Pro

This machine has been very good until now. Here is a list of error reports this week.
These errors occur after the machine is idle for a few minutes, up to the time (30 minutes) I have the screensaver to start. From what I can tell, instead of going to the screensaver, it shuts down. But in some cases it could be after the screensaver starts.

[FONT=Arial]I don't know much about minidumps, just read some other threads on this topic. How do I post them, and find them. Or do I need to?[/FONT]
[FONT=Arial]I'll try doing the diagnostic scans mentioned also in those earlier threads. Took me a while to get the name of the HDD (Hitachi). Had to first figure out how to open the case.[/FONT]
[FONT=Arial]As the Hotfix report mentions sql, I do have a MS SQL Server 2005 that I cannot install the latest MS update for. There's a workaround for this but it's pages long. A weekend project.[/FONT]

[FONT=Arial]Any advice for these problems would be welcome.[/FONT]

Go to C:\windows\minidump. Minidump files have a .dmp extension. Select all the .dmp files. Right-click sending the files to a compressed(zipped)folder. Upload that folder as a file here...

I hope the attached file (9 files) is correct. I used WinRAR and had to change it to .zip.

In the thread
Drive diagnostic utilities compendium
the list includes the manufacturer of my HDD :
Hitachi / IBM - DFT "Drive Fitness Test",
but as I pointed out in a reply to that thread, the DFT does not work for the main HDD of the PC, the drive I want to test.

When I removed the HDD to get it's manufacturer, the drive appeared in pristine condition. All contacts shiny and like new, no dust.

Again the same issue happened today. Instead of going to my screensaver, the computer shut down after I left it for the time period specified before screensaver cut in.
Same "serious error" and BSOD messages.

Tried to add more to above post but edit time expired. How about not having a time limit?

The hard drive is failing

I had recently changed in Display the time period for when the screensaver starts to 30 minutes, from the original 15 minutes (had been 15 since forever). May be coincidence but it was after that that the problems started. So yesterday I changed it back to 15 minutes, and the screensaver started up normally. Coincidence? Does the screensaver connect with other programs that could cause a conflict?
