Let's see if you guys can help me figure out what my problem is. After 9 months of problem free operation, my system started locking up. My mobo is an Abit IC7-G and I am running two 37.4gb raptors striped on the intel raid controller. What happens is the screen freezes and hard drive activity LED stays lit. Then a few minutes later, it will sometimes resume after the LED turns off. I have run Memtest on the system, and the memory tests fine. I have run the WD hard disk utility, and the drives test fine. One of the drives freezes for a while then resumes during the test, but it eventually completes and says it's fine. Would you guys agree that it is most likely the sata controller on the motherboard?
