Cpu high temperature problem

I played around with W8 on an Asus notebook with a 1GHz CPU and found that each programme will open over the top of another.You could have many trying to run and causing the CPU to overload and freeze.
Waiting for the activity to slow from startup by observing the LED activity of the hard drive usually means all startup programmes have loaded and there is less draw on the CPU resources.Trying to access other software while startup is incomplete will compound sluggishness especially if the laptop is a netbook or has a low speed CPU.
If you experience the issue again please wait a few minutes before trying to access or cancel any programme to see if will work through any bottleneck created.

Your Dell laptop has low RAM/high CPU usage, a lot of games tend to use high CPU, so your laptop could be a little old for newer games, so you should upgrade it, or you have a lot of files on your laptop and maybe you opened to much high CPU usage programs.

Maybe the power supply need to be more powerful.

u need bigger ram

While your computer is on, see if the fan attached to your video card is working. If it does, check the temperature inside your cpu. Overheating is one of the reason for logging out on window during online games. If possible additional cooler fan must be install inside the cpu. If that did not help suggest you replace your video card.

it sounds as if your windows xp pro has not been activated. reload with the proper code or phone microsoft on number stated on activate windows.
hope this helps.

Have you checked the temperature of the components?

If the temperature reaches too high of a point, it will automatically shut off, either to preserve the components, or just because it fails.

Make sure that the components you have in are getting enough power from your PSU.

Have you run a memory test? It's unlikely, but that could cause your problems.

If none of this helped, respond, and I'll be sure to help you out further.

The fans in most desktops do run whenever the unit is on. Only high end/ performance/ or self built systems usually have self adjustable fan speeds.

the thermo switch determine how high and how long the fan need to run to obtain the proper temperature, it will be a consern if the fan doesn't run.
as far as the upgrade of your machine. do you have enough RAM (2GB minimum) and how is the CPU?(1.6GHz or better) can the CPU handle the operating system. Since you didn't mention that, and by reading what you say, I believe the machine is not able to handle the Vista, that is why the fan is running at high speed and non-stop. The CPU is getting hot, and the power supply is pulling lots power.
Vista loading takes approximately 1-2 minutes, dependent on how many applications you have installed and what you have on the desktop.
roll back to XP from Vista is no possible, the only way is to reformat and reinstall XP.

HAL - Hardware Abstraction Layer (hal.dll)
HAL is Microsoft’s abbreviation for the Hardware Abstraction Layer, the technology and drivers that let the Windows NT, 2000, and XP operating systems communicate with your PC’s hardware. HAL is one of several features–along with the NT file system (NTFS) that replaced the much less secure MS-DOS–that make NT-based operating systems more secure and reliable than Windows 95, 98, and Me.
HAL.dll prevents applications from directly accessing your PC’s system memory, CPU, or hardware devices (such as video and sound cards)–a method that can prevent many device conflicts and crashes. Unfortunately, HAL.dll sometimes also slows or stops DOS games and programs, which need to load their own memory managers or control hardware directly for better performance.
With HAL.dll in the way, developers must rewrite or even abandon their older software in favor of newer, HAL-compatible versions. Microsoft has pressured hardware makers to provide or support technologies such as MMX, DirectX, and 3D graphics language OpenGL, all of which allow fast but indirect access to the advanced high-performance features of video, sound, and CPU hardware. Such access also makes for a better visual experience when using Windows for Web and productivity applications; improved graphics performance is evident all over Windows XP’s new user interface.
XP also offers some new compatibility-mode features that let you run programs meant to run under earlier operating systems, but, frankly, most DOS-based and even some Windows-based games simply won’t work with the new OS.
