I built my computer a year a ago and I haven't had any signifigant problems untill last week. My computer randomly shut itself off and ever since then I can not get past the start up screen. The orbs begin to fly around but then the system either locks up or restarts. I can not access safe mode or even revert it back to the last stable mode. I tried re installing Windows but after downloading the files from the disk the computer freezes and restarts. I have purchased a new set of ram but that does not seem to have solved the problem. Any suggestions?
