Hi guys, Pc was working fine this morning, shut down fine, won't boot anymore. I just get No Input Signal on my monitor.
The system is powering up fine (i think), as all fans and LED's are working perfectly, just wont transfer anything to the display.
HDMI cable/monitor have been tested with an xbox and another pc, and are working fine. I dont have a VGA around to test, but shouldn't be the cables which is the issue
I dont think its a power supply issue, as I say the led's and fans are all working, and this is a consistent problem. Nothing is being displayed, ever. Usually with power supply issues the problems are intermittent (or so i think)
I can't see why the graphics card would have broken (the HDMI is plugged in here), but just to be sure, i plugged in my old, super slow graphics card and this also didn't work (had no drivers installed, but shouldnt make a differance)
I have taken both RAMS out, switched them around, tried one at a time, in all RAM ports. Nothing helped
I also can't hear if theres any beeps when i turn the machine on. May be due to noise of fans, or the fact I have no idea what im looking for, but I can't give information on any beep codes.
No new hardware
I can only guess there's something wrong with the CPU, motherboard or BIOS?
Any help at all would be awesome!
Thanks, Sam

I just tried the new power supply to the mobo 24pin, and the 4pin cpu power slot. Removed everything i could (drives, disks, cards, ram) and then tried powering on.
I get the cpu fan spinning, but no mobo sounds. I guess my mobo is dead
Should i go about replacing by buying the exact same model, or if there anything specific I should know about before looking for an upgrade?

I would swap in a known working PSU. they fail in many ways.The current PSU is at least supplying power to the LED's, fans and also graphics card. Don't faulty PSU's simply give intermittent power? Nothing has happened to the PC since it was last used, so i can't imagine that it would just die out of nowhere, yet give power perfectly to certain parts of the system.
None the less, I have a kinda crappy 300W supply i could try
