I have an HP Pavilion 9515f...a few days ago it just randomly shut off and since I've tried to boot it back up I get no video signal whatsoever. I've tried ever possibility - both VGAs, SVGA, HDMI, no input works whatsoever. My internal fan starts spinning only to stop after about five seconds. I've often gotten fan warnings/issues at boot up but I would hit ignore and it would work fine. 


I changed the power supply unit today and I still have the exact same issue. An additional concern I have now though is there is a burning smell from the motherboard...I thought it was the internal fan so I took it out but I still notice that smell.


I assume this computer is about dead (this computer is probably over 7-8 years old) but thought I would get some ideas as to what might be happening here and if there is any way to salvage this?


I should note upon bootup there are no beeps or sounds to indicate problems. When I got errors with the fan in the past I would hear beeping, this time I get nothing. The large fan continues to spin though. I don't check how long it stays on for but the system does not shut off immediately.

Off the top and without having the unit here in front of me, I would guess your mainboard failed. If you were getting some kind of system warning about your fan, that is when you should have examined it. Sounds like possibly the circulation fan failed, the unit overheated and the mainboard blew. That would explain the hot-plastic smell you detect. That would also explain why the fan shuts down a few seconds after restart.
