Specs: Windows XP
I have a k-35 Sony laptop My hard drive crashed on me so I called Sony and they said that the biggest hard drive it’s been tested with is 250 GB so I’ve installed one and put XP back on the computer but it has taken a lot longer than normal when it resets it takes about 5 min to get off the black XP screen with the loading bar when it finally loads up CPU usage is almost always at 100 I have nothing on the computer but XP and the updates for it I haven’t cleaned it out yet but the air from the back is hot could it running hot make that much of a difference or could it be something else?

Are you sure there was a problem with the original HDD & not the CPU? Because it sounds like your CPU is overheating & "throttling"....that would cause the laptop to run very slow. Try blowing the dust out of the cooling vents.

I tried to hook up the other hard drive to my desktop as a slave and it froze my computer and wouldn’t load it up I also brought it to best buy and they couldn’t get it to come up either. If the CPU is overheating and throttling is it better to take it apart to clean it or to just blow it out. Also do you think the CPU may be bad or just needs to run cooler?

You state the original drive did not work at Best Buy, but have you verified the 250GB one is good? How old is the 250GB drive

CPU cooling is important to keep the system from shutting down randomly or throttling when getting too warm. blowing it out is a quick way to check for dust buildup and system operation. If you get lots of dust and the blowout helps then the best cleaning would be to get to the fan and remove all the dust.

It appears you also might need to check your memory for errors with memtest 86 or another program.

I just bought the 250 GB right before I put it in its a western digital 5400rpm and 4mb Cache it seems to be running fine but I guess it might be slow for some reason. Everything loaded on it fine and I could see about 230 GB of free space after the load and the recovery partition. Is there a possibility that the hard drive is bad and just running slow or do you think it’s the CPU? I have seen the CPU usage go down to almost nothing if I let it sit long enough without doing anything.
