HTC Desire Will Not Turn On
The HTC Desire will not power on.
The charger may have broke and may be not charging the HTC Desire. Usually the stock charger that comes with the HTC Desire is subject to break. The wires in the charger can wear out due to all the movement and use on a day-to-day basis. To test if it is the charger, try charging another device with the charger that came with the HTC Desire. If the charger does not charge a different device, then the Micro USB charger needs to be replaced.
The power may not turn on because the battery is not working properly. The battery may possibly be dead or even inserted the wrong direction. Try taking out the battery and inserting it properly. The battery may also have outlived its shelf-life and it needs to be replaced.
Non-functioning Charging Port
If the charging cable and battery are both functioning properly the next most obvious problem would be the charging port. If you look into the hole that the charger goes in you will notice a prong sitting in the middle. If this prong is bent, broken or not present you will need to replace the charging port.
The Circuit Board is Broken
If none of the previous items fix the problem the circuit board may be fried. Although this seems to be unlikely that there is absolutely no feedback from a short-circuited motherboard it is not unlikely for the entire circuit board itself to not function at all either due to disconnection from the power source or fried due to water damage.

HTC Desire SD Card Problems
When the HTC Desire is turned on the SD card can’t be accessed or it is not found.
There is no SD Card in the Phone
The SD card memory may not be able to be found because the phone is missing an SD card. Try taking off the back of the phone and checking the SD card slot to see if there is an SD card in the slot. If there is no SD card a new one should be purchased to be installed in the phone.
The SD Card is not Properly Inserted
If there is an SD card in the phone it may be inserted in the wrong direction. The SD card should be removed and properly installed in the phone.
The SD Card is Full
It is possible that the SD card may have reached its maximum memory. To test if it has reached its maximum memory try deleting a few objects, such as pictures, to be deleted. If more space becomes available then the SD card needs to have more items erased off of it or it needs to be replaced with a new one.
Welcome Window Appears Repeatedly
No matter what you do, you can’t turn the phone on without having the welcome window appearing.
Factory Reset the Phone Using Hardware Buttons
A factory reset may provide an easy solution to the problem. This may fix the problem before actually opening the phone and looking at the hardware. Be sure to have all your information backed up because some information might be lost. To do a factory reset turn off the device. Press and hold the Volume Down button, and then press and hold the Power button. Wait for a screen to appear and then release the two buttons. Press the Volume Down button to select factory reset.

Overheating the CPU
The HTC Desire may be repeating this screen because of a heating issue. It can overheat which may have caused your problem. Overheating can damage or even break components of a phone. If your phone has overheated, then the problem most likely lies in the CPU, the central processing unit. If this is the problem we recommend replacing the CPU.
