Upload Error

I did do a search before posting but was unable to find the same issue, apologies if I missed the answer somewhere else . On one of my computers (XP Pro machine) I am unable to upload any sketch to my Uno. I Get the following errors:

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer

I am able to use my laptop without issues, so I don't think it's the Uno. I've tried different USB cables, USB ports, removed & reintalled drivers, and ran a System Restore. Any suggestions?

So three days of the problem and I fix it a few minutes after registering and making the post. I noticed on my laptop in the bottom right it says Arduino on COM24 and on the XP machine it was identifying as a MegaSomething. Changed the board options under tools and it worked.

Glad you got it fixed eventually.
