I have an Studio XPS desktop that won't boot into Windows, startup repair doesn't work, System Restore fails. I have run Dell diagnostics on the system and it's really strange. When i do the Pre-boot System Assessment the Hard Drive DST says Warning - Hard Drive - No Hard Drive Detected.

I currently have 2 GB RAM (1 GB X 2). I tried to install 4 GB more (2 GB X 2) and my computer would not initialize after power on. Is it even possible to upgrade this computer? Do the larger sticks have to be installed in the first to slots? I have never worked on a Dell and this has me stumped!

I've been having issues with my XPS 435mt turning on for several months now. It started where the computer would only turn on after being left off for a day or two. When it wouldn't turn on the power button would flash amber whenever you pushed it
