HiJack This won't help you much since this isn't any malware but an ATI driver issue for some reason pointed at with the ATI atiumd6a.cab not cap file. You are likely running into a display problem as well as seeing several system files missing or being reported as missing.

The first thing you can try right off would be a run of the System File Checker tool with the "sfc /scannow" command typed in...? Well if you can find the Run command line option right click in the corner where the Start screen pops up or open a command prompt.

For Windows 7 since you have 8 listed as your OS the Start>Run is right there for that. The WMP file missing as well as the others may be from an initial bad install of Windows unless the files pointed to are found to be present and only misreported by HJT.

That was cap not cab! My goof when finding the same file in the System32 folder. Reinstalling the same Catalyst version should clear that one up for you as far as the display file.

The latest Cat. 12.6 is a beta version seen at AMD Catalyst

That covers the laptop you have there as well as two other Mobility Radeon gpu series.

The other page for the Mobility Radeon to pick and choose the OEM manufacturer from is seen at GPU-28041: Information on AMD Mobility Radeon Graphics Drivers for Microsoft Windows

The Mobility Radeon Driver Verification Tool is one to grab from AMD Catalyst

You're welcome! Otfen it turns out to be one simple thing like a missing driver out of a driver set or part of an app where the cpu is still being tasked to load it.

The explorer.exe file is the main executable for the desktop gui being caught up in it. Then you see the "explorer.exe not responding" type errors often enough.

Don't forget to go for the driver verification tool just the same in case you run into something like this again.
