I am having Palit GT 240 DDR5 Gfx card, for past few days when I power on PC, it boots, shows welcome screen and after few minutes PC reboots with no display showing.. then I have to switch into onboard mobo slot and it shows display..
What might be the issue?
remount the ram modules ( clean the ram slots and rams as well ) and test with memtest86+.
I think, problem is with Gfx card, when I insert vga cable in onboard slot, it shows display..
you mean when you are uisng the onboard video everything is fine, right ? then it's must be a gfx card related issue - anyway, remove the gfx card, clean it, clean the pci-e slot and remount the gfx card properly.
