Slow Pentium4 with frequent hang using Win XP


I am in lot of trouble since I purchased this computer.  The computer hangs a lot and takes a lot of time to start.  After starting, the fan of the processor starts making lot of noise.  I have even removed, cleaned the dust and reinstalled the fan.

The configuration is as follows:

INTEL 865 GVHZ Motherboard
RAM - 512 MB

Please help me in getting it resolved.  It seems that my hard earned money is getting wasted !

With Best Regards,

What are you comparing the response time to?  How do you know it's slow?  When it hangs, where is it hanging, and what did you do just before that?  You have to be more descriptive of what the problem is before anyone can pinpoint the cause.

If it's hanging, then either you have flakey hardware, or the OS is corrupted, or both.  I'd start with a memory check (memtest86), and if that runs with zero errors, I'd do a clean install of the OS and see if that cleared things up.

The noisy fan could be bad bearings.  There's nothing you can usually do about that but to replace the fan, and unfortunately this happens all too often.  However, if the fan is still running at a reasonable speed, it's only an annoyance and it isn't responsible for the crashing and lockups.

Shall I reinstall the OS? If yes, then that would mean I would loose all the software's that are installed there :(

It takes about 3 minutes to come to desktop after starting the system.  At times, when I access CD-ROM along with other applications, the computer shuts down.  I updates my Anti-Virus daily, and there is no virus or firewall on my computer also.

Shall I contact Intel directly to replace the hardware, as I have purchased it only few months back, and I think there must be warranty on these parts. Please guide.

Well, first you shoud run a memory test (memtest86).

If you have a spare hard drive, you could do the reinstall on that, just to see if the system seems stable with a clean install.  Presumably you have your software CDs for all of your software, so you wouldn't "lose" the actual software, but you would have to reinstall it (agreed, it can be hours or even days of work).  Of course, you have the ability to first do a backup of all of your data.

I don't see any indication that the CPU is bad, and while the motherboard is a possibility, memory and even the power supply are as likely if not more likely.

here is what i would do :
first, check what applications are started when booting; you can check this by running msconfig from the run box. then check in the startup tab and services tab for the items that are started and disable all those you do not want to start. (in services tab, click hide MS services first)  - now check the startup time again.
second, you can do some testing :
-memtest86+ from :      --at lest 5 passes
-run a scan disc for errors : in explorer, right click the disc, select properties, tools, scan for errors
-run BurninTest to check for other problems :      

and if it is still slow you can return it and have a warranty replacement

BTW did you use a 80 ribbon cable for the IDE connection?
and check in device manager if the ide channel settings>advanced are set to DMA, not PIO
