then tried to scan RAM for errors.could not find cd so used USB stick but laptop did not boot from USB,change few times boot setting too. but instead usb it always boot from HDD .so i tested USB use to boot some Linux os ,it work fine and boot from Linux OS.

so i get stuck with USB issue now..


HDD test









In my experience, multiple and varied bsod's are generally caused by one of the following (in order of likelihood):

1) Major piece of hardware has failed (motherboard, cpu, power supply)

2) Malware

In my experience, multiple and varied bsod's are generally caused by one of the following (in order of likelihood):

2) Malware


First, run a fill scan with your AV to rule out the malware possibility. My first guess, however, is the motherboard, cpu or ps.

Defender is fine - just run a full scan. I don't really expect it to find anything. As I said, it's almost certainly a hardware failure.

If you mean a new mobo then yes, you have to buy and replace the motherboard. If you go that route, just make sure to purchase it from a retailer who will accept a return just in case that's not the problem.

anyone know how to find real reason behind these crashing ?

Only deterministic, predictable, and consistent crashes have some "real reason" that can be determined directly. Your BSODs are completely arbitrary, in seemingly random drivers with equally random errors.

For a start though, the system is infected. Aside from what was detected, who knows if there is malware that isn't.
