Xp hangs on startup screen

[ericiscool]

I have a custom built with 3.2 p4, 1 gig ddr dual channel ram, asus motherboard, 120 gig hard drive, nvidia geforce 4 128 MB. with Windows Xp Home service pack 2 installed. i have a printer, and a wireless network inserted into my USB (i read up and people with a similar issue had usb problems?)

here is whats goin on:
My machine was running just fine last night, but it was amazingly slow compared to normal, so i restarted and At first when I tried to restart my computer I got an "Error occured while reading disc... press ctrl+alt+del to restart".... after restarting and going through BIOS I could get to the Loading screen for Windows....but it stays there and never loads. I can get into Safe Mode, but dont know what to do from here.

You have a driver conflict of some sort. Can you boot into SAFE MODE? OK - yes. Then run MSCONFIG and the Startup Tab. Uncheck all of the drivers. Then disconnect you network thingy. It should boot and load Windows OK. Then connect your peripherals (USB- hot plug) and see what happens. Go back and check MSCONFIG and see what is now checked. If it boots OK, then you can start adding checks one by one until you find the one causing the problem.

ok so by turning off a few services in the msconfig > services window i got this machine running, and i scnaned for adware and viruses, found over 300 adwares, and 5 viruses. removed them, and the pc has been fine for a few weeks.
Now randomly my computer crashes and blue screen tells me "disk read error occurred" and thats all, it wont start up in normal xp and ill try to get it running in safe mode, chances are i can get it to run in safe mode. is this a driver conflict? do i have a bad hdd? wahts the deal?
