Re: Huge slowdown on T520 after updating through TV System Upgrade

Hard you gone to drivers in Device manager and selected Roll Back?

Re: Huge slowdown on T520 after updating through TV System Upgrade

It doesn't give me the option to do so.

Re: Huge slowdown on T520 after updating through TV System Upgrade

That would imply the driver did not get changed. You can check compare versions if yours is current.

Re: Huge slowdown on T520 after updating through TV System Upgrade

[ Edited ]

This is probably normal. Because some binaries were updated, .NET Framework will use idle time to recompile them into faster code. You should notice a process or two called mscorsvw.exe that takes up CPU.

If you want to expedite this process, go to Start, Run,
C:\Windows\Microsoft.NET\Framework\v2.0.50727\ngen.exe executequeueditems

 

Also, if you have a platter drive, remember to defrag it after significant software changes on the system. Windows will try to do it every Wednesday at 1AM, but that's not always possible.

Re: Huge slowdown on T520 after updating through TV System Upgrade

ColonelONeill: Good to know its doing that but if has to wait for each Wed and the system is being used deferring the process it could be a long time completing. It would have been good to have a prompt appear asking if I wanted it to complete a systems update like that.

Re: Huge slowdown on T520 after updating through TV System Upgrade

I ran the .NET things and defragged -- it didn't make much of a difference. My computer's still running really hot, there's high DPC latency, etc. As for not being able to roll back the integrated graphics driver, I'd guess that's because I was never able to actually install a new driver, only uninstall the one that was there (and seemed to be causing problems).

Re: Huge slowdown on T520 after updating through TV System Upgrade

I don't know if this helps at all: two times in a row, I tried running the Procmon (Process Monitor) tool, and each time, it opened the window, and as soon as it loaded I got a BSOD. The description for both of them was SYSTEM_SERVICE_EXCEPTION, and it's attributed to ntoskrnl.exe.

Re: Huge slowdown on T520 after updating through TV System Upgrade

Try running a SFC /SCANNOW from the commandline. Maybe something got botched somewhere.

Re: Huge slowdown on T520 after updating through TV System Upgrade

I did one at the start of this, but did another one just in case: nothing. "Windows Resource Protection did not find any integrity violations."
