Hey guys, I've had this problem for a while now and I don't know what to do. Simply put, I try to connect all my devices to the PSU and the computer boots up. Then, one restart and then my 9800PRO says the Video Card isn't connected to the PSU and is not receiving power. I then have to proceed to rearrange all the cables and connect them differently over and over again until I can manage to connect both HDD and the video card. It's rare that I can connect both my DVDrom and DVD-R without the computer freezing after.
I started out with a 370W PSU, a XFX5900, and upgraded to a new mobo ASUS P4C800-E Deluxe. Everything was fine but after a year or so the 5900 started spamming me in-game/windows that the card wasn't receiving enough power and it would lower performance. I rearranged the cables and it worked fine for a while and it started happening again. Naturally, I tested another PSU and everything worked fine (my brother's 470W Enermax), but since it wasn't mine I had to buy another one. By then, a friend of mine offered me a Prescott 3.0ghz 800FSB 1mb and threw in a 550W "Rhycom" PSU which was in perfect condition. Again, after a while it started giving me the same problem. My 5900 stopped working, so my brother gave me a 9800PRO which I'm still using. I bought a new mobo (P4P800 SE) in case the problem was due to a semi-fried mobo but I'm still getting the problem.
I'm going to buy a new PSU unit to make sure it's not the PSU, because I'm really out of ideas.
Any thoughts? Feel free to e-mail me at firstname.lastname@example.org
or sent me a PM.
Oh yeah, sometimes when my computer freezes, I restart it and then gives me a "File *** not found. Please restart the computer" something like that and it does not boot my primary HDD (WinXP)... I rearrange the PSU cables and it boots up again :/
