When we change motherboards, Windows rarely runs right if the install was from the other board.
Add that installing Windows is far from simple enough yet with drivers that may be out of date with the CD that came with the board.
Here's what I missed in your post -> Is this is the old Windows install?
Hi The problem is the following. I had a motherboard m2n68-cm, it broke and the pc shop gave me a M3N78-EH. Today I received it and have some serious problems with it and i want to know whats the problem because i cant tell. I had no problems at all with the M2N. The games and Windows 7 are lagging in waves. these waves are lowering fps and intrerrupting audio .Crysis 2 for example.Every wave is lagging the game for like 7 seconds.its like 10 playable,7 not playable.Its very stressful.The temperatures are ok both GPU and CPU.Mayble the processor is not fitting well...dunno...
Heres the system:
__Ati RAdeon 4770 512 GDDR5 Pci Express x16 2.0
__4 gb Kingston Hyper-X
__AMD Athlon 64 x2 6000+ Brisbane 3.1 Ghz
I repeat the problem did not occure on the m2n68-cm Mobo
PS : BIos is up to date,temps are ok...whats the problem?
