i bought a Systemax prebuilt with no OS a couple years ago and its been perfect...till now. I left it running and laid down for a few hours and woke up and it was off...but the num lock light was on on the keyboard. I hit the power on button and nothing...so i thought it was the psu. I bought a new psu 500watt and still nothing. to make a long story short I followed every step in the "perform these steps" found here http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems and still nothing so im guessing the motherboard and i ran across this article (might have been on this forum but im not sure where i found it) http://hardwarelogic.com/articles.php?id=5418&asesessid=8a6ad2934481bea9eb14fe8e02d020e193e24014 i did this (jumped the green to the black wire) and the puter kicked on and the fans started spinning but as soon as i took the jumper off it shut off. 2nd time i left the jumper on for about 3 seconds and took it off and it turned back off. Not sure if the puter should have stayed on or not but this is the most its done since it went dead. So do u guys think its motherboard???...should the puter have stayed on after jumping??? Thanks for any help that i get. If its the motherboard, I plan on getting the same board and just switching the processor over to it unless u guys think the processor is dead too??? I hope not thou...thanks
