I have recently bought a new Motherboard(XFX 750a SLI) but it refuses to boot (It does not give a post beep hance it does not boot) now i checked all the jumper settings but i also noticed that the IO panel is not working it may well be the PSU because it only has an extra 4 pin PCI express power connector but the motherboard wants an extra 8-pin PCI Express connector. I cant find an adaptor but the guy at the shop said it should still work... any ideas? any solutions? HELP!!! .
