Hi, I just finished assembling a computer for a friend of mine (specs as follows). Asus H87M-PRO Motherboard, Intel i5 4570, MSI Radeon R7 260X 2GB, Silverstone Strider 500W ST50F-ES, Western Digital WD Black 1TB WD1003FZEX, Crucial M500 120GB SSD, G.Skill Ripjaws X F3-12800CL9D-8GBXL (2x4GB) DDR3, LG GH24NSB0 24x SATA DVD-RW Drive OEM.
I am pretty experienced at assembling computers and I am used to the usual array of small problems that arise on the first boot, but on this computers first boot it posted all right, got to the BIOS setup page. So I pressed F1 to enter BIOS I didn't change anything and then I exited by clicking "Discard changes and exit". The computer then rebooted but again went to the BIOS setup page. So I went into the BIOS again and set up the boot order so that the priority boot was the ODD. But whenever I tried to boot from the ODD (with a windows 7 disk or a windows xp disk present) the computer immediately shut down. I have also tried booting from a bootable usb running ubuntu, but the computer shuts down immediately as soon as i manually select a boot device.
I have also noticed that every time I start up the computer the fans spin for less than a second then stop, then repeat a few times before the computer properly starts up. I have noticed this with ASUS motherboards before but this could have something to do with the problem.
I have tried unplugging both the hard drive and the SSD and just booting from the ODD, as well as unplugging all three and booting from a usb but the computer behaves the same. I have checked that all power plugs are attached properly, that the ram is seated properly and that the gpu is seated properly.
I am pretty sure that there is nothing shorting against the case, but the only way I could be 100% sure is by removing all the parts and booting up in a test bench arrangement, which i would rather not do.
Please let me know if you need any information.
I have done some further testing, and the problem seems to be the graphics card. The computer works fine running off the iGPU but whenever the graphics card is the primary device the computer wont boot, and will default back to the bios setup page. Is this a power supply issue? or something to do with my GPU?
