I just installed a new motherboard because my old one failed. I installed the following: MSI K8N Neo3 motherboard AMD Sempron 3100 Processor 2 gib Ram 250 gb harddrive 120 gb harddrive CD and DVD burner etc. When I start the computer up it blinks to a black screen about 10 times before getting to windows. Then when I click on my name to logon, it does it again. And again while working on programs in windows it continues to blink. I called windows and they say it is a hardware problem. I have never seen this. Does anyone have advise for me.
