Iscsi Raid
Can you help with computer problem---It sucddenly can't find the graphics card?
After over 2 years, my computer is saying it can't find any compatible direct 3D graphics. Even the screen saver won't work.
The problem started after I had to turn off the computer directly by pushing the on/off button on the tower and not by shutting down.
I'm not sure where my 3D program went, or why this is happening. Any advice or help would be appreciated? I have tried restarting it, and shutting it down normally and restarting it. I also downloaded a virus program after the problem started and although there were no viruses all the malware and other programs were removed, but hte problem still happens even after restart.
I have a PC, with windows XP.
ACPI x86 PC based.
Two Intel Pentium D CPU 2.8 GHz.
Sigma del hi def audio. (this is the only device listed under audio/video in my device manager.)
Intel 82801 HR/HH/HO SATA Raid Controller
Microsoft iSCSI initiator
Start at the beginning -
If you can use your monitor to look at the device manager, your graphics card is working, at least at a reduced level.
What are you running that complains about 3D? XP's basic desktop uses 2D graphics. If you're not running anything special when this message appears, possibly you downloaded some new graphics program that needs a 3D card your computer doesn't have?
Best bet would be to go to your graphics card/computer manufacturer/motherboard maker's website and download the current video card drivers for your video. It sounds like the software may have been corrupted, possibly by the rough shutdown.

What is NAS?
NAS stands for Network-attached storage. This is the name given to contributed data storage technology which could be connected directly to a PC network and offer centralized data storage and access to varied network clients.
NAS is a hard drive storage system - including configuration of RAID, with its LAN IP address than being connected to the computer department that is giving applications to workstation of network users. It has its own program for mapping and configuring file locations to network attached equipments. A Network-attached storage could be included as part of a more complete solution similar to SAN.
Description
NAS varies from traditional file serving and DAS or Direct Attached Storage in that the OS and other program on the NAS offer only the storage data’s functionality, data access and the supervision of these functionalities. Moreover, the NAS unit doesn’t limit clients to just one FTP. NAS systems typically contain 1 or more hard drives, often set into logical, superfluous of redundant arrays of independant disks (RAIDs) or storage containers, as traditional file servers do. NAS eradicates the responsibility of serving file from other servers on other network and could be deployed by way of commercial embedded units or through computers running NAS program.
NAS utilizes file-based protocols like NFS or Server Message Block (SMB). Contrast NAS's file based method and use of well understood protocols that has SAN (storage area network) that utilizes a block based approach and runs over SCSI over iSCSI or Fiber Channel.
Minimal functionality or stripped down OS are utilized on NAS PCs or devices that run protocols or file applications which offer the NAS functionality. A "leaned out" Free BSD is utilized in Free NAS, for instance, which is open-source NAS software intended to be organized on computer hardware. Commercial embedded equipments and consumer network appliances can utilize closed source OS and protocol implementations.
As these tools have IP addresses, they could be accessed directly.
In a Network-attached storage, since the storage are separately located to the server, program files are served more rapidly as they are not competing for no different resources.
Another benefit of Network Attached Storage is that, you can have different servers with dissimilar OS storage, management and backup of the data can be centralized even when you’re in the environment
Some of the great advantages of this storage device include its expandability. It is so easy to add more storage. This as well brings an extra fault tolerance level to the network because you could include mirror RAID features.
