Here's my situation, my computer was a P4 1.7 Ghz, 512mb DDR Ram with a small 14 Gb Hdd, so the other day my dad bought new hardware and i got my friend to install a 160GB HDD and another stick of 512 MB Ram.

I really know nothing about all this, thats why i got my friend is a really good with computers to help me and my old 14GB HDD was set as the slave drive to the other.

The old one has not yet been formatted, I was gonna scan it first...just to see if infected and then format it, but anyway, got XP on alright and the new hdd is working except im getting what it seems to be internet problems.

THe problems include, browser pages just loading up into errors after like 30 minutes of being connected, my system seems to be lagged and my CPU ussage is always at 100% and the only thing i see plaguing it like that is what is: IEXPLORER.EXE SYSTEM, now i know just ending that process would help right? well even when not connected it still plagues my system =\

something also i noticed with my connection to the internet....the sent and recieved bytes are going through the roof...like they rise alot faster then it usually did and it seems when it reaches a point, that is when internet pages just stop loading all together, like within 20 minutes of being connected...my connection will say that bytes sent is around 50 MILLION and bytes recieved around 20 million, and it was never like that before so im concerned with that...maybe thats my problem? cause it wasn't like that before

also since upgrading my computer with the new HDD and RAM, all my downloads have gone slower...like they sucked before...but now its just pitiful....speeds at around 8kb/sec and im on a DSL line

so those are my internet and what not problems...i dont know what to do...im confused and in need of serious help...any advice id REALLY appreciate it

thank you for your timeIf it were me I would put a 20Gb drive with an 8Mb disk-cache as Master and slave the 160Gb drive to it.

When you formatted the drive did you also partition it and have you formatted to FAT32 or to NTFS?

Did you format directly using the XP CD or did you format to FAT32 and convert it?

I would check to see the cluster size with chkdsk and see if it says 4096 byte clusters.

How is the Spyware/Adware situation? Are you using SpyBot SD, AdAware SE & SpywareBlaster?

How is your power supply coping with the additional RAM and the big drive?Not all DRIVES are compatible with each other, btw. TRY disconnecting your old drive.

(I use an 8·0Gb (8192Mb) drive C: for XP) the rest is partitioned for storage.your pc maybe infected by svhost exe....download a trojan remover?
