[SOLVED] Temporary unresponsiveness after startup Hi all, I recently bought a refurbished laptop and after fixing most of the problems I've encountered, this one doesn't seem to want to go away. For a quick run down of specs, I'm running Win7 Home premium 64-bit on an Advent Roma 4001, Intel Dual Core T4400, 4GB RAM and 500GB HD. During the "Please wait" and "Welcome" messages it can take up to 2 minutes just to log on, but the main problem occurs after logging in. The CPU usage, apart from System Idle Process (of course) is pretty much zero, and the RAM usage is down at about 30MB. Everything seems responsive, however, when I attempt to open a program or process I'm getting incredible lag. If I'm quick enough, I can open up a window or two or a program before the lag strikes. The strange thing is it doesn't actually appear to be unresponsive (apart from when it lags with my internet browser on-screen and the loading animation freezes). The programs all load given time, usually between 2-5 minutes, and for all they run slowly for an amount of time, still run. I don't notice any processes or services that are hogging the memory or being specifically tied to causing the lag after executing them. The slowness is recurrent through every execution I make - through opening windows explorer to my internet browser, a program or just opening up the start menu - everything lags for the same amount of time. Something then just seems to "click" after a while, and everything runs smooth as pie; the programs I've tried to open up all flick on as if they were queued and waiting for something to clear. I've tried chkdsk, messing around with msconfig, including performing a clean boot by turning off all non-windows process and startup icons within msconfig (and I have kept those settings for every boot, no luck), made sure all drivers are updated and functioning, seeing if the problem occurs in safe mode (it doesn't), checked event viewer for any critical errors (there are none, but a hell of a lot of standard errors, mostly, 7 Disk) no viruses or malware have been found after searches, ran sfc /scannow, checked the memory with a repair disk... I've tried a lot. From other problems with the system I've had to reinstall the OS 3 times and this has occurred on each install, so I'm not going through that again. It doesn't happen for around the first day after an OS install and crops up slowly, which tells me there's something that can be fixed, I just don't know what. It may be worth noting that I can't seem to do a System Restore, since after running the restore I get a message pop-up after restart that it couldn't locate C:/Windows/assemblys/NativeImages etc... I have tried not to disable services in msconfig since it would delete my restore points, but I'm tempted - the problem may be there. I haven't tried Driver Verifier (god forbid) and I'm really hoping it's not a hardware issue (since the problem is cured after a few patient minutes, I wouldn't think it was). Does anyone have any suggestions? Thanks, Anton. EDIT: The problem was the services. I was reluctant to tamper with them since it means you lose all your system restore points, but the problem was there. After disabling everything by running 'Diagnostic mode' in msconfig, the problem was gone. I'm still not sure what the service was, but after enabling my critical processes only, voila!
