I built this computer in early 2006. Decent components (amd 4400+, 1 gig ram, video card, etc.) It can take a heavy load of dvds/games/transfering so it must be a hardware malfunction, right? My usb ports seem fine; I can plug my mouse, keyboard, ipod, or harddrive into the usb connection in the back of the computer and windows will recognize them and let me browse files. But as soon as I start transferring large files (500 mb or more) my computer just stops functioning. I can't hit ctrl-alt-del, it won't eventually unfreeze (left it on overnight) so I just have to hit the restart button and only part of the transfer will make it to the hard drive or ipod. Its not just my personal devices it will do it to anything you try transfering large files to. Very frustrating >:( I've checked different forums and have not really found a solution. Checked the device manager, no problems. Even bought DriverMax so I'd have upgraded drivers. Still does it. Please help me! I don't really feel like taking it to see anyone what are your DIY solutions? Ok I just tried changing the virtual memory for the connected drive. It worked well after I rebooted and allowed me to transfer a 1gb file. But the next file I sent was larger and the machine crashed at about 1.5 gigs of data transferred. I played with the virtual memory and tried changing it for both the c drive and the attached external drive and it continues to crash. Now I get a flash of blue screet of death before it self reboots.
