My specs: Windows 7 64-bit q6600 3gs memory 500gs hard drive 9800GTX PSU: 375W So my computer has been freezing (always forced to turn off pc) when I'm not active on it. It acts as if it went to sleep and can't be woken back up! I have everything set to NEVER for power save options. I have no anti-virus programs running. I've got Ccleaner and had Malowarebytes but it kept crashing so I uninstalled it. For my videocard issue I noticed I was out of date so I go to Nvidia website to get update driver and when I try to install it, it stops like 1/3 of the way!! Every time!!! I have rebooted the computer plenty of times, forced to turn off the pc plenty of times as well. Right now I'm running a VGA Standard Graphics card. However, my resolution is 1440x800. I thought VGA is usually 800x600 automatically? Whenever my PC freezes and I turn off and on I always see this in dos: No boot device available - Strike F1 to retry boot, F2 for setup utility. Press F5 to run on-board diagnostics. I ran diagnostics and it shows no errors BUT sometimes it does and here is the error it shows: Error code 0147 Msg: Error code 2000-0147 Msg: Unit 0: Optical drive BIST - - spindle test failed. I'm always having to F5 in dos now to get back to my desktop, it takes like 15 tries it seems sometimes. I swear my computer has a mind of its own. Any kind of help would be nice. Thank you.
