Hey everyone, I'm here in Florida right now. My laptops in awesome working order, but my Uncle's is messed up right now. I've come to you guys for some help with his Desktop PC. It's a Dell XPS T450 Dimension Computer. Here's whats up: At certain times while he is online, his Aniti-Virus Program (Norton) glitchs up on him, and he gets a message like this: SINGLE-BIT ECC ERRORS IN MEMORY BANK 4 Also, when he tried uninstalling a program, he got: Uninstall Programs no longer needed NMAIN Caused an Invalid page fault in ModuleKernel32.dll 9210 Stuck Key My Uncle also says he only has 57% memory at times. Any help is greatly apprechiated. Thanks! :thumbs
