Sometimes but not always (maybe once out of every 4 startup attempts) my computer will hang immediately after startup, just when the desktop and icons have fully appeared. Also the startup chime is absent whenever this freeze occurs. The mouse cursor does move but is unresponsive. Ctrl/alt/del does nothing, and I have to hold down the power buttion for 3 seconds to get it to shut down. Trendmicro online and Kaspersky online scans find nothing, although Kaspersky scan got halted with error report message:
Event type: BEX P1: ScanningProcess.exe P2: 5.0.1.86 P3: 47584f5e
P4: mdb.ppl P5: 6.0.2.678 P6: 45ffbfca P7: 000014f6 P8: c0000409 P9: 000000000
