It just goes on off on off continuously after few minutes some times it boots up fine till windows and when i try to use it it again shutsdown and i noticed sometimes when i use hairdryer to blow drier and blow hot air in pc sometimes it boots up fine works for 15-20 mins then again shuts down.

My canned random reboot Rant
Random reboots are usually caused by the PSU, the RAM or software AND in that order of likely-hood.
PSU - If you can borrow/swap a PSU for testing. sibling/friend you can swap out the PSU and each system will be testing the other.
RAM - run the system with one stick of RAM see if stability returns if not Test all the RAM with memtest 86 for three passes or overnight. if you get no 0 errors after more than three passes the ram is good. with the random reboots I would suggest running this test after the PSU swap or after the PSU has been cleared.
Software - Drivers or other issues can cause reboots. Boot to a linux distro on a USB drive. mint linux will boot to memtest86. you can run the OS from the USB and await reboot.
end canned rant

Yeah, first thing I'd do is replace the PSU, which is absolutely frightening low quality. Make sure you get the current PSU properly recycled so that nobody tries to use it again.

Unfortunately, that's far too low a budget to get even a below-average power supply.

If you're truly desperate, you can get a newer Corsair VS for just under 3000.

Fairly low quality, but at least it's a stepup from the literal garbage tier.

The first budget PSU I'd be actually comfortable with is the Corsair CXM 450, at 4799.

You may find slightly better deals at other sites, but you'll never get anything you actually want to use at 1000 rupees.
