My PC is a ASUS desktop MC1740 with processor AMD A8-3820 APU, OS is Windows 7.
Background: Zonealarm tune-up utility found a multiple of broken links, etc. both in file system & registry. Used utility to repair. Around the same time (before repair, I think) I noticed that PC is slowing down/slow response. Checked Event View and found a number of failures inc. "bad block on Harddisk1/DR1" . Ran a CHKDSK command on C:/ D: & external hard drives. D drive came back o.k. (but following the chkdsk this drive was completely empty). On C: it found 73 parsed records (?).
Windows keeps crashing / Ext Hard drive now connecting and disconnecting continuously with the error message s.th. like "this files has not program associated with it". Checked MS tech support and downloaded the drive.winfix7 file w/o success, then downloaded the folder.winfix7 file also no success.
I now have to restart PC every 20 min and am unable to work with exterior HD because it keeps disconnecting.
I am attaching a selected events log (just an overview) HELP. Thank you.
