Unfortunately, we have probably an 8 hour time difference from UK to America, so our posts get delayed, but your patience is very good. I read through your other thread, and it gives me further information /questions, that I will ask, now. Old motherboard Are you now putting the old motherboard back, OR, have you now done so? and using same graphics card, and same psu that you had before inserting new motherboard ? With original ram ? Or, using on-board graphics vga ? Did it go into bios O.K ? Did screen show O.K ? and with on board graphics, or, your old graphics card ? Try it with the on-board graphics, with the graphics card removed.-did it work- still same problems ? Don't worry about constant re-starts on old motherboard, although I need to know about that. We spoke earlier about the psu- If it is the same one from the previous setup, I would test 12v, and 5v rails ,as I notice no-one had suggested testing it previously, as a faulty psu can give so many curious problems. If all o.k (using your old graphics card) then try the new ram in the old motherboard- see if it makes any difference........ After the tests-if screen works O.K, If everything checks out , then replace with new motherboard. New motherboard On your new board , on page 16 of the manual says not to use a 3.3v agp card, as this may damage the motherboard, so check the rating of your agp card if you can while on the old board. This motherboard supports 1 x AGP slot for 1.5V 8X/4X AGP card. ONLY TRY THE ON-BOARD GRAPHICS- DO NOT INSERT A GRAPHICS CARD, USE on- board vga point. Do not put the graphics card in whilst testing to get into bios screen - IN FACT , NOT UNTIL YOU HAVE INSTALLED AN OPERATING SYSTEM, JUST TO BE SURE. A graphics card , if in the allotted slot could confuse the motherboard until an operating system has been installed, owing to driver availability, so just use the vga connection on the rear of the motherboard- This would also eliminate the graphics card from any problems in getting in to bios. If everything worked, but with problems on the old motherboard, we need to see definitely need to see if the psu and graphics card are not faulty. You may be able to print the manual from http://www.asrock.com/mb/Intel/775i65G R3.0/index.asp?cat=CPU#Manual But I believe you noted that the library might not allow downloads.
