I recently upgraded to WinXP Pro. It worked fine until i got online with it, when i started getting out of memory errors. I increased my paging file size to max, then set it at system managed after finding the former didnt work.

After trying to DL an antivirus demo to no avail (didnt have time/had to return my modem as i share it with my mother) I found my performance in the game NHL 2004 to have gotten incredibly choppy.

I suspected I had got a virus from KaZaA, so i deleted KaZaA.

I also installed from my Motherboard disk Trend PC-cillan 2000. I needed to update it, but first i scanned (and found no viruses) and reset.

Now that its reloaded, my computer hardly moves. Its so slow i cant navigate menues.

Any tips?
Heres the specs on my PC:

Hard Drives:
MASTER: 76 GB Maxtor 7200 RPM Running Windows XP Pro VIA GRUB
SLAVE: 8 GB Fujitsu 5500 RPM Running RedHat Linux VIA GRUB
CPU: AMD Athalon 1700+ (1466 MHZ)
MONITOR: 19" Viewsonic
VIDEOCARD: Nvidia GeForce 2 64MB
RAM: 256 MB SDRAM (IMO probably a contributing factor to my troubles)
CD: 52x (no burner or anything)

Im thinking Il be taking out my master hard drive, putting it on my bros PC as a slave and burning stuff as backup, then wiping the drive. Any way around this (as I cannot function without my Windows XP segment as Linux does not support my modem)
