I have searched the forums for this problem and usually I can sort this out myself but maybe I am missing something so I would like your help please.
I bought an asus motherboad (i forgot which model an asus micro atx) and i5 processor. It had onboard graphics, I used 4GB memory from my old core 2duo setup. I bought a PSU as well to go with it corsair 850 watts.
Sometimes it wouldn't start and other times it would run for a few hours with that hardware. Then it ceased to start at all.
I bought a new psu and still nothing. So I beleived it was the board and took it back to the shop.
I then bought the p8p67 atx with the i5, same 4gb ram and same 850 watt psu. I added a GeForce gt from my old pc to get a picture.
I kept getting the red light so I removed one stick of memory and left a single stick in. It worked for a while and I did burn in tests with all my hardware and it past with flying colours.
After successfully using the computer for about a day it now won't start. I get the red light on the motherboard. I suspect the memory but it worked in my last computer they are CORSAIR XMS3 1333Mhz 9-9-9-24 1.12v 2GB (x2)
A single one passed the burn in test but I couldn't boot with 2 in.
The CPU passed the burn in test too.
Sometimes I can get to the bios but it after a while it sticks on the bios screen and I can't move.
I'm sure you can all feel my frustration when a quick upgrade suddenly requires an engineering degree and remortgaging the house
