I,m running winxp but when my sytem is starting up it take about 10mins,before it anything happen not sure if a virus can get into the memory,and slow it down any help would be appreciate.
thank.

Hey,
Try this.

Help 1.
Make sure ur ANTIVIRUS is updated. Then SCAN ur SYS.
U may try this in safe mode (Will be more efficient)
If antivirus is not up to date remove HDD and Connect externally to another sys with a good antivirus, and scan.

Help 2.
When it boots open run and typr MSCONFIG, the press ENTER
the do the following
-go to STARTUP TAB (u'll see a list of progs that run when windows bootup)
-uncheck all execpt ur antivirus.
-apply and click close
-u will be prompted to restart. (do so)
note: this will help a little.

Let me how it goes 4 u.

thank for that mate but it didnt make any different, its slow when its in dos starting up.The first thing it show is the bios that on my system then 10mins before anything etc happen

OK!
It then is likely that your Hard drive may be dieing.
Run "scan disk, or check disk /f" in CMD. ie: dos mode ok/.
