check your plug in in side of your system case. your monitor shows orange light while power
is on

Ah, I got it fixed now, thanks anyway. I just took the whole thing apart and rebuilt it with a few ajustments. I put some more Arctic Silver on my processor, I took out the motherboard battery to reset the CMOS, I reseated the RAM sticks in different slots and I changed around my wiring a bit, some power leads were connected to a few too many devices and fans.

Hope this helps if anyone has a similar problem.

I replace the heatsink with a ASUS Silent Sqaure Pro Heatsink Cooler and Ive added the grease compound between the heatsink and CPU. Now there is power going thru the computer but nothing happens. Doesnt start up or do anything but turn on. Please help me on this and tell me wat is going on with my system.

Did you try and overclock your memory if thats the case a simple BIOS reset may fix your prob.

Thanks i thought thats what i needed to do should i disconnect the hdd's to be sure not to lose any data and how do i reset it? it's an msi rx480m2 mobo? cheers

Data wont be removed by a reset infact it doesnt touch your hd but you can remove your HD if it makes you feel more secure
how to reset:1 remove your cmos battery from your motherboard keep it out for a half an hour or so(the longer the better)replace and restart.

thanks i had to use the jumpers aswell but all is fixed now cheers
