Had a computer random freezes (thread about "Strange SATA HDD/Radeon 9600 behavior ...") and solved it by lowering AGP/PCI speed...
After that PC doesn't freezes anymore, but when i copy large files to SATA drive, i got "Delayed Write Failed" error poping up, and Event Viewer is full of errors like "An error was detected on device \Device\Harddisk3\D during a paging operation", "The device, \Device\Ide\IdePort2, did not respond within the timeout period." and copy is not possible as it takes forerver to complete...
Help somebody! Thanks in advance.
