While going through the list of troubleshooting tests I ran memtest86 overnight. I checked it before going to bed, 1.5 hours in with no problems. When I got up, the machine had restarted and now it will not boot. Power light comes on, fans spool up, but nothing. Digging around found some information about resetting the CMOS. Is that the recommended way to fix that problem?? And if so, what's the proper way to perform the reset? I'm guessing that's a pretty good sign bad memory was encountered. Info: 2.5 year old HP box, OEM Windows 7 Home. Upgraded memory from 4gb to 16gb in January. This brand: Pareema 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model MD313D81609L2 - Newegg.com Also, updated power supply in January due to a noisy fan. And replaced the CD/DVD burner in July because the other gave up the ghost. If I can get the box to reboot, I'll replace the memory with the old 2gb sticks to test. Thank you for any help.
