Unable to connect to internet

Sorry, I must have been typing faster then thinking, I have two other computers, which I am able to connect to the internet though!

Yes this is correct I have three computers 2 of which can connect via wired and wireless. I do belive it is a malware problem because of the fact that that the computer is slow and acting odd. I am using anothere forum for help with malware, which can take up to five days for a reply. I guess my next course as far as this forum goes is to wait until the malware problem has been resolved or disregarded as a problem. I will reply then. Would you prefer me to reply to this post at that time or start a new post? Thank You for your help!

Yes I did that, and I know that the problem lays with the computer becuase when I connect the computer to the modem directly the problem remains, I think it is a problem with malware. I am still geting help with that so we will see. Thanks for your help

Update:
These are all the steps that I have done, no have restored my internet connection
1. Find and eliminated all malware
2. Connected Laptop to router to ensure that it works, it does
3. Connected problem computer directly to modem
4. Connected Laptop to modem to ensure it works, it does
5. Purchased a new CAT5e cable
6. Did steps 2-4 again
7. Purchased a Cat6 cable
8. Did steps 2-4 again
9. Downloaded and used winsockfix
10. Rebooted in Safe mode with networking
11. Via laptop downloaded newest driver, transferred to problem computer via flash drive and installed the driver
12. In the same manner as step 11 downloaded and installed “Update for Windows XP Service Pack 2 (KB884020)”
13. Disconnected DSL modem from all three cables
a. Via Network connections disabled LAN connection
b. Reset the DCHP Client
c. Shut downed computer
d. Reconnected all three cable of DSL modem
e. Allowed internet light and DSL light to come on fully
f. Restarted computer and reactivated LAN connection
14. By means of Device Manager reduced link speed to 10 Mbps/ Half Duplex
a. NOTE: At this point limited internet access is available, I am able to download virus definitions, however I am still unable to go on to internet explorer
b. NOTE: When on anything higher then 10 Mbps/ Full Duplex the Ethernet light that correlates with the problem computer blinks, as if it is trying to connect or find the NIC. When at or less then 10 Mbps/ Full Duplex, that same light becomes solid
c. NOTE: It is not a problem with the router or modem, this problem does not arise when connect via Ethernet to my laptop
d. NOTE: Before OS loads the same light blinks, when OS loads and persuadably before the modified speed limit is applied, then the light becomes solid. Before this problem arose the light would become solid as soon as the power button on the computer was turned on.
15. Uninstalled the the network adapter, restarted computer and reinstalled network adapter, then reinstalled newest drivers.

Unless I am mistaken this can not be due to an OS corruption because the problem arises before Windows XP loads.
Do I need a NIC card? I am still under warranty under Dell, is a new NIC card covered under that warranty? If I decided to install the NIC card myself, which I can do, would this violate warranty? Is there anything else I can try to correct the problem outside replacing NIC Card?
I hope I stated everything clearly and with precision, please tell me if you need clarification.

Thank You for your help,

Sorry I'm a bit of an n00b :(

Is a PCI ethernet adapter = NIC Card?

Thank You So Much!

Do You recom. any NIC Cards or manufacturers?

Thank You,again SOOOO Much!
