Problems with Radeon HD 6450 driver on Dell Dimension E521

[1337B337]

I've exhausted every solution trying to get this card to work on my PC.

I dual boot Ubuntu 14.04 and Windows XP, and the card works perfectly fine on Ubuntu.

But for some reason, every time I install the recommended drivers from AMD (Catalyst Control Center 14.4,) and restart the system on WinXP, everything works great until the next reboot/shutdown.

Afterwards, I get the "No AMD driver found or blah blah blah," message, indicating something wrong.

I've shut off Windows Update, forced Windows to ignore driver signing, cleaned up with Guru and CCleaner and did a fresh install, I even went into the BIOS and changed the primary display to the Radeon card instead of the integrated one; all of these suggestions I've found here on Toms Hardware.

NOTHING has worked so far.

If you need any further information, such as the updates I have installed or other things, I'll provide it.

If anyone can help, It would be very greatly appreciated.

The card may be bad, test it in another system with Windows and make sure the power supply can run the card. The Linux drivers are likely not using many functions of the video card which is why they are running fine when Windows is not.
