My sister has a brand new Dell still under warranty for her home business. When it began screwing up, she called Dell support. After three days of several hours at a time spent with them on the phone, she was told she'd have to reformat, thus losing all her stuff (back ups, yes, but all of the office customizations and applications for her business would have to be redone and back ups restored, and they had payroll to get out, etc.). In the meantime, I had described the problems here with the error messages, and was advised to run a memory diagnostic. So I told my sister to not do anything till I got there, drove two hours there (my sister, by this time, was ready to crack, lol, she had a sick child vomiting, had been on Dell's customer support for DAYS, had payroll that had to be gotten out, had an impacted tooth and needed a root canal.......and then Dell tells her she'll have to reformat!

) and ran MemTest on her computer. Several HUNDRED THOUSAND errors later

I call Dell back and tell THEM what the problem is. Not a single person my sister had talked to had ever suggested running a very simple, quick, memory test that is INTEGRATED into Dell's computers to check the memory. When I flat out told them it was a simple memory problem and we want the memory replaced (and threatened to call out the flying monkeys), the guy finally put me on hold and then came back and had me run their Dell diagnostic. Took only a couple of minutes and came back "failed."

EVERYTHING could have been resolved DAYS ago, and I would not have had to make a 2 hour trip, if someone had just thought to run that simple little thing.

Even this guy, evidently did not know about it, since he had to put me on hold to go talk to someone else who evidently instructed him on it. They had me run it twice more. Each time it failed.

FINALLY, he had me remove one stick of memory at a time (she had two 1gb sticks) until we found the culprit and once that defective stick was gone...........gosh, her computer worked GREAT.

Better than it did when she first received it.
I shudder to think what my sister would have done had she reformatted, reinstalled and fixed everything back up again, and STILL had the same problem!
But it took ME telling THEM what was wrong before it was diagnosed correctly and fixed.
They did, however, send her a replacement memory stick.
