My dell 3521 is restarting in booting screen from last 2days. I checked preboot system assessment but found no errors. It shows everything is working fine. Also removed the battery and pressed power button for a while but the problem remain as it is. Please help me what to do?

Dell 3521
Core i3
500gb / 4gb
Win 7 32 bit
Recently no installation in last 2-3 months..
Was working fine till the day before yesterday.
 
What kind of temperatures are you getting? You can use HWMonitor to check. Might be overheating.
 
So you are saying that you are using the system and it just all of a sudden reboots on you? If thats the case, its not overheating. Overheating will shut it down completely. If its rebooting on you then the system is faulting and its designed to do that. Access safe mode options and move the highlight bar down to disable automatic restart on system failure. Next time it happens, it should give you a blue screen. If so then we can go from there. Also check event viewer for any signs of errors that may have caused the reboot.
 
There is no temperature problem. Also safe mode is not showing in boot options. There is only legacy boot and uefi boot is showing in which legacy boot has hard drive /cd,dvd/ network.. Uefi is blank..
How to disable automatic restart on system failure
P.s I didn't see such option in setup (F2) menu..
 
To access safe mode options, press the F8 button on startup. Then follow what I said to do.
 
Going to download win 7 and will try to repair startup...

Here safe mood is not appearing in f8 as it should be don't know why, also I had never tried to use safe mode in my lappy before.
 
I'd suggest doint what John said first. Repeatedly tap f8 until you get options to boot into safe mode. This will tell us if it is a driver issue. You can then use system restore to go back to when it was last working. You can also do this from the WIndows DVD if you want to go down that option aswell.
 
Unless the F8 key is broken, thats how you access safe mode options. Try using a usb keyboard.
