Using a GPU which needs higher Watts than my Power Supply

[a_random_freak_]

Hi,I bought a pc and gpu a week ago..the first game i tried on it was CSGO..it worked great..but then i decided to play FORTNITE..When i was playing it My Graphic driver crashed and the game stopped working..I searched everywhere and tried a lot of solution but none of them worked...Yesterday i downloaded GTA V and in the middle of the game My Graphic driver crashed AGAIN..
After a lot of searches i found that my graphic card needs more Watts than my PCI have..
I found somewhere that underclocking might fix the issue..So i underclocked my GPU using MSI After Burner but the game still crashed...Do i need to underclock my GPU more and can someone tell me the correct settings for MSI AFTER BURN..
SORRY I AM A NEWBIE
My PC SPECS
Core2Quad Q9400 2.86GHz
HP-D2402E0 HP 240 WATTS POWER SUPPLY
8GB DDR3 RAM

MY GPU : Nvidia Gt 730 DDR3 128bits (2GB)
THANKS!

You're better off just replacing the power supply.

There are 3 different models of the GT 730, but all are recommending at least 300w. You have a an old OEM 240w psu, which I highly doubt is capable of that anymore - these things degrade over time, so it's providing less than 240w.
No amount of undervolting is going to help.

320 W standard efficiency active PFC (CMT)
Is this enough for my GPU
Also i'm out of money so isn't there any temporary fix by reducing the performance?

Down voting the answer will not change things. You have a hungry processor, a weak and aged psu, you're lucky it only crashed.

If someone had suggested that underclocking might help then ask them, I don't believe you'd be able to underclock it enough to make a big enough difference. You'd need to lose perhaps 50w across your whole system.

You currently have this 240 W standard efficiency active PFC (SFF - Small Form Factor):

You can't fit the 320W standard efficiency active PFC (CMT - Convertible Minitower) PSU into your computer case:

There are no after-market PSUs that will fit into an HP Compaq 8000 Elite Small Form Factor computer case. HP uses a custom form factor for that PSU.
