Blue Screen
My computer is a HP model : m8300f

Left my computer on downloading some things over night and when I woke up it had restarted, after log on I keep getting a blue screen and the computer restarts. I havent done any recent changes to the system.

Blue screen
PFN_LIST_CORRUPTION
***STOP: 0x0000004E ( 0x00000099, 0x000A50A6,0x00000002, 0x000A5085)

Got this one in safe mode:

MEMORY_MANAGEMENT
***STOP: 0x000001A(0x00041201,0xC0395D18,0x3D5F6025,0x8700C9A0)

Test the ram in Vista by running mdsched.exe

Read the additional info and run the extended tests.

If you cannot start in Safe Mode, there should be a "repair" option on your F8 menu. The memory tester as well as other recovery options are there.

That does not tell us very much. I see that you are a "beginner" and probably have not had a lot of experience of using Forums like this one. It is really important that you provide as much information as possible so that we can accurately assess what you are doing and when you receive an error.

For example, with System Restore, did you run it from within Windows after boot and login or did you run it from Safe Mode?

Do you know how to run SR from Safe Mode?

Automatic restore points taken by Windows will always have some kind of explanatory title, such as, "Windows July update"... or something similar that tells you what Windows was about to do before taking the restore point.

Which restore point did you use?

How many restore points do you have and how far back do they go?

Blue Screen problems are most often associated with hardware malfunction - that is why Rolling Rog suggested running a memory test.

However, it is often helpful to eliminate a possible software problem - e.g. a corrupt file - before you get involved with the hardware, particularly if you are a beginner. If your problem is software related then System Restore is your first option to fix the problem.

Once you are sure that it is not a software issue then you can start checking hardware, usually in the order of : - RAM; Hard Disks; Power Supply; Overheating; Motherboard...etc

See if you can run the memory diagnostic from the "repair" environment available through the F8 boot menu (usually there -- or load the Vista disk if you have that).

Alternately, and perhaps more conclusively, create a bootable Memtest86 tester:
