My son was home from college and playing some game on my desktop. He's back at school and sent me a note saying he thinks I might have some bad memory. I don't see any errors. The System shows that I have 1.46Gb of memory, which is what I originally installed. He was helpless in giving me advice on how to tell if it's defective. Is there any kind of diagnostic tools to determine the status? Thanks. Tom

There are diagnostics that can be run.

I'm curious as to what sparked his note, so I would investigate that before I threw any effort into checking anything on my system.

Down load Memtest86 you will need to unzip and load it to a floppy then shut down and reboot with the floppy in the drive, the testing take awhile ans it is thorough. Any faults that show up means there is something wrong with the memory stick or sticks. If you have two repeat the test to find out which one is the culprit.

that being said it is possible for memtest to miss something. had a friend who was having frequent blue screens, all memory related-had her run memtest86, which found no errors, however when she popped the case open, the memory chip was quite literally fried, had burn marks all over it. However, this is the exception-not the rule, ive found memtest86 overall extremely accurate.

If she had two sticks the one may have read well but the bad one was not recognized so it was not tested.

Thanks everybody. I took a look Memtest96+ instructions. I don't have a floppy drive. The other options (USB Flash for example) are way too complex for me to handle. Maybe it's time for a new PC anyway. My cd/dvd drive just crapped out on me, too!

A question are you experiencing anything wrong with the operation, or is it that your son told you so and you are now looking for something that really is not a problem.
Some of the newer more intense games run like Krap on 1.5g ram, could be not that your ram has an issue it is just not up to gaming!
