Is it possible that the Bios Update was incompatible?
I did see one other BIOS update (F.0c) but if you were using F.07, I don't think you were supposed to replace it with F.0c.
If the system was on warranty, this would be worth a call to HP.
System specs: HP Pro Book 6540b Windows 7 Professional 64-bit (original) Intel(R) Core(TM) i5 CPU M 520 @ 2.40 GHz ATI Mobility Radeon HD 4550 BIOS updated from F.07 to F.21 (can't be rolled back) What happened: I updated the BIOS drivers from F.07 to F.21. That model HP comes with discrete video Ram (512mb) so it's not like your system Ram is bad.
Problem: Things I've tried: - Removing drivers from device manager (the artifacts from programs disappear but I can't play games) - Installing the latest drivers from ATI's website - Installing the beta drivers - Installing the drivers from the CD that came with the laptop - Fresh install of windows and all of the above The problems you show in the screen shot and example details corrupt video Ram.
It does point to the issue being specifically with something you can't replace... It could be a coincidence that this popped up when you updated the BIOS, nothing specifically listed in the revision notes at the HP download page detailing that update state it deals with the video chipset at all... It unusual that the problem occurred at the same time.Everything you did surrounding the drivers is right up there in the HP tech support playbook.Hi, Try doing the update by doing a clean install instead.- Go to Device Manager and uninstall the graphics card driver.- Open Programs and Features and uninstall anything related to your graphics card.- Download and install the latest driver from the manufacturer of the graphics card.
