hi,there is problem in my pc when i start my pc it takes to much long time on windows loading or system hard disc speed go slow, i format my system many times but the problem come again.
my system specifications is .intel dg33fb motherboard,intel core 2 duo 2.4, 2gb transcend ram 800mhz, msi 8600gt 512mb, 160gb hard disc.os windows xp. please help me.
i also installed nod32 antivirus system but they cannot help me. is there any type of virus problem or hard disc problem.

check out computer management . .. .
right click my computer > manage > event viewer (in the menu) > system .. ...

in the system menu. .. .there will be a lot of events recorded....check what are the errors are there..... there will be an error mark . .. or more..
then u will understand what the problem is.....i hope...

i think your HD its ok...mybe u need to defrag it...

if problem always come again... mmmmm....maybe to much instal software program...uninstall it ....

1. check your task manager (ALT+CTRL+DEL) >>>for normal and no application running PF USAGE must under 200 mb. and CPU usage under 4%

2. check system configuration utility (STAR MENU > RUN > MSCONFIG) on service tab, disable program if u don't use it , and same on startup tab

3. restart PC....will go FASTTTTTTTTTTTTT

have you already tried another HDD ??
maybe its's your motherboard or something else....
if formatting the disk wont help then it must be something else i think...

Well that happens to me as well, and I have a quite good PC I think, but when I use the Ubuntu partition on the same disk it load much more quickly, so briefly is the OS windows su@#s Only for games . . .

vista emulates a 32 os on a 64 bit core so it is slower than it could be. when most of the programs become 64 bit then it will speed up tremendously. but defragging sounds like the best solution yet. (In my humble opinion )

well, u have tried formatting the sys and if it still does not work then i guess it has to be motherboard
I hope this helps...

scan all the partitions
perhaps there maybe a virus in the system volume information folder, it cannot be removed easily
try kaspersky antivirus
had no prob!

Check the DMA settings of your hard drive controller. Make sure it is enabled in the BIOS and that Windows correctly detects it.

As already suggested, defragging may help but note that Windows Vista really takes longer to start up on a typical machine. If your computer has only 2GB of system memory, I would advise that you stick to Windows XP or Vista 32-bit version.
