Startup very slow,crash at welcome and crash randomlythen OS not found

A few weeks back PC crashed out of no where and BSOD appeared.. didnt take much notice until it says OS not found when restarting.. but after a few tries it went back to normal for a few days then these few days it started to startup very slowly and may sometimes crash after typing in the password at the welcome screen.
sometimes it would also randonly crash and when restarted OS not found will appear.

Hi tank3006.

The latest BSOD in the uploaded zip is of 31/01/14, so it is not supposed to reflect the exact situation of today.

Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.
  1. Click on the Start button
  2. Type “msconfig (without quotes), click the resulting link. It will open the system configuration window, with the "general" tab selected.
  • Click the "startup" tab. Click "Disable all" > Check the touchpad driver SynTPEnh back > Apply > OK.
  • Click on "services" tab. Check the "Hide all Microsoft Services"; Click "Disable all" > Apply > OK
Then try to boot again normally. Is it BSOD still?

ok will try it but to be honest it just BSOD just like a few times on startup after it crashes randomly like when im surfing before I am able to use it after a long startup time
P/S: Sometimes it shows operating system not found and i would need to restart the com a few times to get it to work.

P/s2 : Restarted the com with what u told to do, it is slightly faster but the only problem persisting is during the starting windows where i can see he orange wifi led light(which it should have lighted on much earlier last time) is the problem delaying the startup. and the blue light next to it which is the processing led( i suppose) is lighted up all time .

My 2 cents worth try running these if only to eliminate those sources (if necessary in safe mode)

tahn3006, It would be advisable to use the Manufacturer of your hard drive's diagnostic test, If your hard drive keeps dropping out, then there is a hardware problem somewhere. I would also suggest check the connections to the drive and make sure both are firmly seated, on both ends,

Will not do any harm to do just that.
