My computer was working perfectly yesterday, but when I turned it on today I got an error. It posted and then went to "DMA-1 Error System halted". I checked all of the cables and reseated the RAM, and the symptoms changed. Now it gets to the "Start System Normally", "Enter Windows Recovery", "Safe Mode", ect. No matter which option I choose, it starts its task and then restarts the computer. It will get to the Windows loading screen and restart the computer. It will just go in a loop until I shut it off. I can still enter the bios and see the harddrive there. What is wrong here? Is it a hardware issue? What can I try to resolve it?
Pentium D 925
2GB OCZ 800Mhz
Vista Ultimate 32-bit
The reason that I'm hesitating to get a new hard drive is that I've been told that the problem may be the motherboard. Upendra09 might be right, but I'd like other people to either agree or disagree with this. I have tried the recovery disc option, but it restarts after it begins to load.
Hmm from what I can tell its either the motherboard or an expansion card error. Likely its the Northbridge on your motherboard failing. Especially since that MB has VIA chipsets. VIA is generally = cheap junk.
Most websites say the DMA-1 error is motherboard related, but I think it seems like the hard drive has a problem. The only cards are a video and Ethernet. I haven't been able to try the recovery disc, because it never gets that far. I would also appreciate an elaborated response from anort3.
Will my chance of losing data really increase with time when the computer is off? Can it wait until this weekend? I don't have anything to save the data to right now.
Sorry for being so short before. As I understood it if it was the HD failing it would have been a DMA 3 error. The site I linked to in my earlier post explains DMA much better than I can.
I still think your HD is ok and if its not an add in card then the Northbridge is about to fail.
I have been wrong before though once or twice. lol
Hope you can get it fixed. Let us know and good luck.
u could take the HDD out and put in to the cheap PC and test it out to see if the HDD was bad or the RAM
if they both work fine then ur mobo is shot.
That's exactly what I did. It turned out to be the hard drive. Luckily, Windows 7 was able to repair it enough to get the data off. I'm even tempted to put the hard drive back in the old computer to see how it works. I'll probably RMA it to WD though. Thanks for all you guys help. I'm so glad to have a desktop and all of my data again.
