Hi, It does sound like there is an issue with the card. Replacing the card is probably the best option. 
Hi I've gotten several errors in the system event log. These both come up several times together: I have used the OMSA software to find out that PCI slot 4 is the PERC H700 RAID card. I can reboot and log into the raid management software. The OS boots and locks up occasionally.  The system alert light on the front of the server blinks sometimes. I can still access the drive. I have a Poweredge R510 rack server with 12 drive bays. My question is do I need a new PERC H700 controller card? new 512MB ram module for the card? I have tried reseating the card in the riser card and the alert light still comes on. What else can I do?
