I have a Dell XPS420 and thought that my hard drive was GIVING out. The system would boot up if I tilted the computer at a 45 degree angle and tilt it a little to the right. Sounds STRANGE but I found this out when I picked the front part up the get a speaker wire free.

I got a new hard drive WD green SATA 500 WD5000AADS. I took out the old hard drive and installed the new one.

Now the fun begins - I replaced a hard drive on my old Deminision computer prior to giving it to my daughter - no problems at all. I was silly to think that type of luck would hit twice.

I put the new hard drive in the XPS and turned on the computer - I had to do the same tilting routine to get it to even turn on. After it turned on I got the message I/O card parity interupt at F000/F1888. The I/O card is the same one that came with the system - no add ons.

I think I may have purchased a new hard drive that I didn't need.

Any suggestions of how I can get the computer to run without the tilting and slanting?

In the mean time - since I don't think it is the hard drive, I guess I will put the old hard drive in and restart the computer with the slant/tilt method. Check the connections between the power supply and the motherboard.I did all the checks and everything is plugged in tight and running.

I replaced the hard drive and trying to get everything back to normal - hopefully, just forgot to back up my favorites for web BROWSING so now I guess I have to access the human computer to try to remember all my favorites sites.

The new hard drive seems to be doing fine. I ran it through a number of boots along with shutting down and turning on. I didn't get any failure notes, etc so I guess it was the hard drive.

Thank you for your HELP. Quote from: dlnc on January 25, 2010, 09:18:24 PM
