Hello,
I had this problem with my PC. When I launch an game or do something it just turns off and restarts after 5 seconds. I checked none restarting after system failure but it wont work.
I havent ran memtest but I will
I need serious help here, please.

macafee, and virus will cause bugchecks but the problem you describe will be caused by the computer power supply or a bad connection from the one of the power supply leads. best to pull the connections and reconnect if that fails, time to test the power supply or replace it.

if the computer just restarts when you enter into a game, I would suspect that the video card is not getting enough power and drawing too much power from your motherboard pci slot. I would check to see that the secondary power connections that run directly from the power supply to the graphics card are actually connected. you can also get a crash in a graphics driver that will not give a BSOD but generally the screen will go blank or "freeze" (generally have to update the graphics driver, or disable confilicting HD audio sources from the motherboard or HDMI HD audio source in the graphics driver)

browser will use hardware acceleration (graphics card). in either case, it is not the video card but the power not being supplied correctly to the video subsystem. The power supply will have a command line that sends a power_OK signal to the motherboard. A good power supply will shutdown the motherboard if too much power is pulled from one of its power feeds. This can happen with a failing power supply or with a bad connection to the supplemental power feed to the graphics card. When the power supply clears the power_ok signal the motherboard should reset and the system goes back into BIOS start up mode. result is you don't get a bluescreen or memory dump in windows.

correct you will not get a memory dump, the memory dumps come from the OS, as far as your OS is concerned the motherboard lost all power the same as if you had unplugged it from the wall.

there can be other causes of not getting a memory dump, i just listed the most likely from your description. If you don't see a memory dump to the screen it will boil down to a Power supply issue. bad connections, one of the power supply lines failing, but the power supply has detection circuits to save your motherboard from burning up and that circuit is being triggered. now you need to figure out if where the fault is.

Most likley gonna call an mechanic. Or put my lazy ass to work. I say its an power drain from an electricity cable fail some time ago. That happend to my older phone while I was recharging it and an
power cable failed and my phone was dead. I suspect some heat. As I started the PC some days ago it started to make an awful sound like an car engine then it stopped and began to ran normal. When I make colder athmosphere in the room and let it shut with the power on it works some good hours, but if I let it without power it wont work very much. This is making me sick. I also think of an virus. And I also suspect McAfee antivirus. I had an bluescreen multiple times some time ago and I read it was about McAfee. When I still read the dump file and decoded it, it said something about genuine intel update...
