I have a Dell 4700 that started giving me memory parity check errors on boot(gets to the Win XP Login screen then errors, the lights on the back of the machine are all green), day before yesterday. The system is ~5 years old and out of warranty. It has been running fine up to this point. I’ve researched the problem on the web and done everything that was suggested in the various posts both here and other forums, with the exception of changing the battery. I’ve removed and reseated all the memory cards, changed them one at time to try determine if one was NG, unplugged and reseated every cable connection, run all of the F12 on board diag’s(they all ran fine), even taken out and reseated the CPU (yep, put new thermal compound on B4 reseating cooler)and checked the PS voltages to make sure that they are OK.
Just before the system 1st crashed it was behaving a little funny. It was warm in the house(mid-80’s) and I thought maybe I was having a thermal problem, but the fans weren’t running noticeably louder. They did what they’re supposed to do during the fan test.
Anyway, I’m stumped. What have I missed? Anyone have any suggestions as to what the problem is?
