Why Is My Computer So Slow?
There are many things that can cause a slow computer such as a virus, spyware, or hard drive fragmentation. Registry problems are one of the most common reasons for a slow PC. Registry problems are accumulated as a result of installing and uninstalling programs which ultimately have a negative effect on the operation of Windows. To get rid of all these Registry errors and get your computer back in shape, we would strongly recommend you use RegistryBooster.

How to perform disk error checking in Windows XP
Chkdsk requires exclusive access to a volume when it runs. Therefore, if one or more of the files are open on the disk that you want to check, Chkdsk displays a prompt asking if you want schedule the disk check for the next time that you restart your computer.
Chkdsk might take a long time to run, depending on the number of files and folders, the size of the volume, disk performance, and available system resources, such as processor and memory.
Chkdsk might not accurately report information in read-only mode.
How to run Chkdsk at the command prompt
Click Start, and then click Run.
In Open, type cmd, and then press ENTER.
Use one of the following procedures:
To run Chkdsk in read-only mode, at the command prompt, type chkdsk, and then press ENTER.
To repair errors without scanning the volume for bad sectors, at the command prompt, type chkdsk volume:/f, and then press ENTER.
Note If one or more of the files on the hard disk are open, you will receive the following message:
Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)
Type Y, and then press ENTER to schedule the disk check, and then restart your computer to start the disk check.
To repair errors, locate bad sectors, and recover readable information, at the command prompt, type chkdsk volume:/r, and then press ENTER.
Note If one or more of the files on the hard disk are open, you will receive the following message:
Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)
Type Y, and then press ENTER to schedule the disk check, and then restart your computer to start the disk check.

DV2000 Problems
Repairing The Display Problem in HP dv2000/dv6000 series
PROBLEM
Last week when I turned on my laptop HP dv2750, there were multiple screens appearing on the display instead of one screen, and some times the screen even didn’t appear. I reinstalled and updated the nvidia drivers (as it has nvidia 8400GM) assuming something might be wrong with the drivers, but when the notebook restarted the multiple screens appeared right from the time it restarted, i.e. there were six boot screens, instead of one. I logged on to the HP website and updated my bios, but the problem didn’t solve. I ran the system restore, but that was also useless. I searched for the problem on the net and found that there is a die-packaging manufacturing defect in nvidia GPU of G84 and G86 which was officially announced by NVIDIA. These nvidia GPU are in most of dv2000/dv6000 series of HP pavilion laptops
Solution:
My laptop’s warranty expired last and was also not covered by HP Limited Warranty Service Enhancement. I talked to HP, they confirmed it as a hardware malfunctioning of nvidia GPU (Graphics Processing Unit), but refused to repair it free of cost (estimated cost by HP was $300+shipping charges). I being a student couldn’t afford that much. As I was out off options so I decided to get it repaired locally.
The local techinian immediately identified the problem. Actually the problem is in the Ball Grid Array (BGA) of Nvidia GPU. With the passage of time (approximately 1 year), the Ball Grid Array Soldering of the GPU gets damaged due to heating. When it gets damaged, some pins of the GPU loses the contact with the motherboard, and hence displays nothing. The local technician told that there are two methods to repair it
