3 days ago, without any obvious changes, on a cold boot, this laptop, Win7 HomePremSP1 64bit/I3 w/4Gb RAM, 440
MB GBHD, 400 MB GBfree, has started to run dreadfully slowly... (yes, I know, it was no rocketship to begin with....but...) by the clock, 6 minutes from cold boot to Windows sign in, 9 more minutes until the desktop completely draws. No errors, no bluescreens.
I have run Mbam, Mbar, and AVG scans, each taking 3-5 hours apiece to scan, cleanly, and substantively slower than previous experience on this particular computer.
Chkdsk reported that master file table's (MFT) BITMAP attribute is incorrect, schedules a scan at next restart, which it appears to do, and then procedes along its very slow way.
Resource Monitor/Disk shows System, svchost(netsvcs) and svchost(LocalServiceNetworkRestricted) as the only Process with disk activity when completely "at rest", no apps running, though often it blanks the screens, as if it itself cannot get enough clockticks to update the display. Clicking on the start marble takes generally 5-15 seconds for response, and often with incomplete icons.
Physical memory shows 1328MB in use, 1531 Free, 948 standby, 204 HW reserved, 85 Modified.
I have tried to do a clean boot with MSCONFIG to run only startup services, and disabled all non-microsoft services. No change in results.
It will boot in safe mode, and runs essentially the same slowness.
It is currently isolated, networking disabled, and apparently willing to (at the pace of molasses in winter) run anything that I throw at it. The fact that I am not seeing any errors (other than an occasional application is not responding message) has me somewhat perplexed.
