Hello, I am currently having an issue diagnosing a problem on an HP Pavilion DV7-3174NR entertainment PC laptop. It is a fairly new machine (probably only 1-2 years old), has 6gb of RAM, and a 500gb hard drive, running Windows 7 Home Premium 64-bit. Also, it is a refurbished machine from the factory. A friend of mine brought this laptop to me hoping that I could fix it. He bought it about a year or so ago, and like I said, it is a refurbished laptop. It worked fine for him up until recently when he was using it to email a large file to someone, when the machine froze up and had to be manually shut-down (by holding the power button). Then, when it was restarted, it would bring up a black and white screen in the boot manager asking how to boot (safe mode, normal, etc). Whenever you select an option, it would bring up the Windows load screen, but then it would bring up a black and white screen saying that some driver was missing, and then would take you back to the screen asking how you want to boot. No matter what option was selected, it would do the same thing.
So, I decided it was probably some type of hard drive failure. But as a last resort, I tried to reload Windows 7. Low and behold, I got it to reload Windows 7 from my disc, and now boots up properly. However, now the computer is running VERY slow and lags when trying to do anything…. Often the windows will become unresponsive and you will have to shut down the machine. Also, it will run normal for about the first 1-2 minutes, but after that it gets worse and worse. Also, the bottom of the machine is getting pretty darn hot. I’m not sure if this is representative of a problem, or this machine just runs really hot. But anyways, now I’m not sure what is wrong. Could it still be a hard drive issue even considering that it is now running Windows (even though very slow)? Is it something like a faulty motherboard or faulty RAM? I’d appreciate any help you can provide. Thanks!
