Freezing Forcing Reset

Over the past couple month we had BSOD now & then and its seems to have returned after i tried fixing my current issue of consistant freezing (mainly on startup, p.s not many startup items just needed programs).
I tried safe mode and security scans w/ malware & Microsoft security essentials which found nothing.
I tried to safemode with networking which itself froze and the PC had to be reset.

its seems after the 4th or 5th time of restarting the pc it works fine.

Im using Vista Home Prem. 32bit
fujitsu pc.

There was no disc with this pc : (.....also can i make my own start up disc?..or isnt there any point being that its obviously corrupt.

thanks for any assistance.

Generally, Freeze could be from number of constraints.

• Junk files
• Low Ram, High Usage
• Back ground program
• Hidden Virus
• Hardware issue

Remedy: Try to delete the temp files, msconfig, try increase the Virtual Memory. Analysis from which date system freezing. Try system restore.

Thanks.
Vijay.
