Normaly, serious memory tests are run with Windows unloaded and in low memory: The first 64K.


It looks like you have some faulty RAM stick(s).

Turn the computer OFF, disconnect the power cord and birefly press the power button to discharge the capacitors before doing ANYTNING inside, like removing and replacing memory sticks.

To find the faulty one(s), remove them all but one and run the test.
If no error are repported, that memory stick is good.
Remove it, place it in a safe place and insert another one.
Repeat the test for all sticks, one at a time.
The stick(s) that show any error need to be replaced.
Bring one at a computer shop and ask for compatible ones.

It's a good occasion to upgrade your memory to as much as the motherboard can hold.
If you have dual or triple channel, ALL sticks in a given bank MUST be of the same capacity.
The sticks in distinct banks don't need to have the same capacity.

Ah!

after 10 minutes of research...

These are error codes.
ME516 is a memory test series (not me 516 as in my 516)
Probably generated from an application called PC-Doctor

The diagnostic is showing an alleged problem with the machine's memory.

Failed Auxiliary Pattern Test error code ME516-3W
Checkerboard Test error code ME516-15W
Walking One Right Test error code ME516-18W
Waling One Left Test error code ME516-17W

Either the memory is good or it's bad - if the PC-Doctor application runs - and it runs in memory - then the memory is probably good - but what do I know?

You do not say what problem caused you to run the PC-Doctor diagnostic.

Good luck...
