My GPU got hacked and after BSOD the PC restarts while playing games. How to hardware reset it?

[ckc037]

This is the second time happening to me, some people hacked my Laptop's GPU previously and its graphics processor was damaged and it is now useless.

This time they hacked my PC's GPU and I got a BSOD(dumping some memory), Don't know what it was dumping but I restarted the PC before it completed dumping the memory.The BSOD never appeared after that.

Now when I play graphics intensive games the PC reboots. I can play Counter Strike 1.6, Stronghold Crusader without any problem , but can't play The Elder Scrolls V Skyrim or similar graphics intensive games.The graphics are jerky which previously never happened and then it reboots.

I'm using (a bit old computer)
Windows 7 Ultimate 64-bit SP1
Intel Core 2 Duo E6320 @ 1.86GHz
Forsa NVIDIA GeForce GT 630 1GB

I'm sure that they hacked my PC and Its not PowerSupply or CPU overheat fault, never had problems when playing these games before with them.
I reinstalled the driver after removing previous drivers using Guru3D-DDU in safe mode.
I did Stress-test for my CPU and its not causing any problem.
When i use FurMark to Stress the GPU the PC is rebooting.

There are no other problems, It only reboots when I play big games.No problem when watching Youtube or other simple tasks.

I think they changed the bios or some other parameters related to the GPU.
Now how do I hardware reset my graphics card to its previous position.
Can re-flashing the original BIOS(if i requested it from the manufacturers website) resolve the problem?
Please help me what I should do?

Sorry for my bad English

I am pretty sure no one "hacked" your GPU. It simply does not work like that.

More likely, you have a driver or a heat/power issue.

What make/model is your power supply? Also, what are your CPU and GPU operating temperatures at idle and under load?

When was the last time you performed a complete malware/virus scan of this system?

I'm from India. My PSU may be got manufactured in India.
Odyssey 450w Computer Power Supply.I think this PSU is not from a big company.
It has no special connecters for the GPU,
My GPU gets its power from the motherboard's PCI-Express slot
I don't know how to find out make/model of my power supply. If you tell me how I can know it, I'll post it again.


Temperature details :
CPU when idle 34°C when under load 50°C
GPU when idle 40°C when under load 58°C (After 58°C the PC reboots, Tested it 4 times)

I'm using Comodo Internet Security (both a firewall and antivirus).
No I didn't scanned my PC anytime (I'm relying on real time detection of viruses, I mean.. detection when the viruses get accessed).Anyway I'll do a Full scan soon for this problem.

This could very well be a defective power supply. Your temperatures are fine.

Complete the scan, for good measure. Do you have access to another power supply that you could swap in to test your system?

When I'm using FurMark to stress-test the GPU, why is the PC getting rebooted when it reaches 58°C.Isn't the GPU overheating or something fault with GPU?

I completed a full scan and no virus were found.
No, I don't have any other power supply.But I'll try testing the GPU card in another computer.

A symptom of a failing PSU is just such a failure. It fails under load, like when the GPU is pulling full power from the system during a stress test. If the GPU works properly elsewhere, then you have likely isolated the issue to the PSU.
