  1. The computer has been having this trouble for a few days now, I installed another 4 gb's of ram into the system not that long ago, but it was running fine after that, no slow downs or anything after that, i installed the new service pack, and it's been slow ever since that, I think that caused this problem. The computer also Blue Screen a little while after the install, power failure, just my luck. and thats when the read/arites got even worse. They got as slow as .8 Mb/s, i have no clue as to what is causing this, any ideas?

    Go to your device manager and look at IDE ATA/ATAPI controllers and find which one your drive is on. Then go to Properties then Advanced Settings and make sure DMA is enabled. Somehow the drive may have got kicked into PIO mode.
