[Jr485]

So i was overclocking my r5 240 1gb ddr3 graphics card. When i moded its vbios and flashed it and then restarted my pc ,everything run perfectly. But after couple seconds of stress test its temp goes upto 96C and pc powered off automatically and starts showing blnking orange light on power button. When i tried to turn on pc again after some time it showed same blinking orange power button light and no bootup screen and no fan runing of both mobo and graphics card.Pls can anyone help that is my gpu bricked?? and it can be repairable by using CH341A programmer or any other method that may work here.

* Mentioning that pc runs perfectly without gpu installed.

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

When i moded its vbios and flashed it and then restarted my pc ,everything run perfectly.
Did you save the VBIOS for your card, prior to the flash, so you had a safe point to fall back on?

If you don't have an iGPU, you're going to need a spare GPU to get display out and reflash the prior GPU's VBIOS with a stable version following this guide;

Sounds like - running the card with modded vbios caused physical damage.

R5 240 is Oland, and there's little point overclocking it because it's bottlenecked by the 64-bit DDR3 memory which only supplies up to 16GB/s bandwidth, worse than most IGPs.

It's a 30w card and if you overclocked it to say the 1000MHz of the also-Oland HD8670, well that's an 86w card and you don't have an auxiliary power connector or even enough cooling.

As mentioned, it should be possible to flash the vBIOS when booted from another GPU, but be careful not to flash the wrong card by specifying what address/slot. See if there is a motherboard BIOS setting to use IGP first or add another video card.
