When I turn on my emachines t3265 desktop computer, it freezes at the logo, and does not proceed to Windows so I can log on. What is the likely problem, and how can I fix it?

Hi there!
Could you try to access your computer through Safe mode? Restart your computer and keep press F8 function key until computer appear the black screen with white writing. Select Safe mode to log on your computer. The Safe mode only bring some basic windows processes to let you fix your computer.
Thing you can do when you on Safe mode to clean you computer are:
1. Delete internet temporary folder/ Clean your hardisk/ Uninstall new software that cause problem
2. Deframent your harddisk
3. Run check disk, check hard disk sectors
Then Restart you computer, to check that your computer can log on normally. If not, you need to go back to Safe mode and back up all your data and try perform a fresh installation for your computer.
Details how can to do thing on Safe can supply to you if you required.
Hope this will hellp. Thanks for reading.

Turn it on.
Hit the ESCAPE (or TAB) key to replace that colourful logo with the technical details of the computer's POST (Power On Self Test) messages. Look for any messages, such as "unable to boot from disk drive" or "disk-drive not detected". Also, remove any CD/DVD media from the CD/DVD drive. Also, remove any 3.5-inch diskette, and disconnect any USB memory-sticks BEFORE you turn it on.
