I have a very slow start-up of my system (typically 9 minutes or so). I have followed all the advice I can find on the web, but mostly there has been no improvement (because I think my system was fairly 'clean' so start with. Any further advice would be gratefully received. The last thing I did was to remove some start up programs, which reduced the time from 8mins 54 secs to 8mins 25 secs.... I fear this might be a combined hardware and software issue, but I'm starting here, if that's OK. Here's some background: - Asus A8V mobo - AMD Athlon 64 Socket 939 3700+ San Diego core running at 2.2 GHz - 2 Mb ( 4 sticks x 512 Mb) Corsair memory, DDR2 PC 3200 running in dual channel mode - Boot disk is Hitachi 60 Gb 7200 rpm IDE with 8 Mb cache - D drive (paging set) is a raid-mirror of 2 x 250 GB Seagate SATA-I drives - Graphics card is Matrox Millennium P650, driving LCD at 1900 x 1200 ( replacement with ATI Sapphire X1650 Pro made no difference; I don't need any 3D acceleration). - OS is XP-SP2 with the current set of security fixes - Security is Norton Internet supplied as a service through Brit Telecom/Yahoo Application set is rich What really bothers me is comparison with a 'smaller' system I also have, with Asus K8V VM mobo and 2 GHz Socket 754 Venice core. The Venice system presents the Windows desktop in about 15 seconds from boot and finishes loading in about 90 seconds; the San Diego system requires about 2 minutes to show the desktop and then another 7 minutes apparently loading things. - There is no virus/spyware/trojan infection on system, according to Norton. I am behind a router firewall. - System has been 'cleaned' with CCleaner, latest version - both drives full defragged - IDE drive is running at DMA mode 5 - system seems to run at about 2 to 5% CPU load most of time - memory used is mostly about 600 Mb except when Photoshop being used, when it will rise to 1700 Mb - BIOS settings all seem to be appropriate - CPUZ says hardware is running at expected speed, aside from 1 puzzling stat: the 'memory ' tab in CPUZ says the memory is running at 157 MHz (FASRAM = CPU/14), but the 'SPD' tab reports 200 MHz on all 4 memory banks I have removed Windows Defender from the system; it made no discernible difference. I have turned off indexing. I have set the OS select boot option time to zero I don'tthink Norton INternet Security is doing any scans at start up. If anybody has some ideas of where the problem might be, I would be most grateful for some suggestions.
