at startup, error, then black screen

Dell Inspiron 1545 notebook
February 23, 2010 at 14:49:25
Specs: Vista 32 bit, AMD 3200+ / 2GB
After vista loading screen I get two errors:
1) WerFault - Application Error, and 2) LogonUI - Application Error.

Both have the same message that the instruction at 0x[address] referenced at 0x00000000 (error 2 has it as 0x00000001) memory could not be written.

Then Blank Black screen with cursor....

My attempt at fixing:
Tested RAM - no issues.
Vista repair startup - cannot find problems!
System restore - any earlier restore point didn't help.

I'd greatly appreciate any advise. Thank you!!

Test the hard drive that Windows is installed on, using the disk
maker's own diagnostic tool freely available from the websites of
all the major disk makers.

Thanks for replying.

I forgot to mention that I can access the hard drive by connecting it with a sata to usb adapter to another computer. I did that to backup the necessities. So it seems the HDD itself is working fine.

As a last resort I will restore to factory settings, but I'm hoping that someone can help me fix the issue...

I'd like to report how I fixed it in case anyone else runs into the same (or similar) issue. Problem is, I don't know which of my experiments actually fixed it, so I'll write everything I tried.

After system restore and startup repair didn't help, I did this: In Vista repair I ran the command prompt.

Type cd c:\
Type c:

Type Notepad. File> Open. Navigate to C:\Windows\System32\winevt, rename Logs to Logs_bad. Right-click> New folder. Name it Logs.

You can insert a USB stick and copy the Logs_bad folder to be analyzed on another computer (which I did but found nothing relevant).

Eventually I restarted the comp and came to a screen saying it needs to run Startup repair, so I let it run again. But unlike other times when it took a second and told me it couldn't find any problems, this time it took some time then showed "attempting repairs", took about 5-7 minutes... restarted and it just WORKED!


Other things to try:
1. Press Ctrl+alt+del or Ctrl+alt+esc, and if Task Manager comes up try to run Explorer.exe

2. Press shift 5 times, and if the sticky keys dialogue comes up, click on the link and see if you can get to explorer somehow.

3. see here for more suggestions.
