PC won't turn on after trying GTA V

[Ted_12]

So my friend has pretty old PC, he has intel core 2 duo e6700 and he took my amd radeon hd 7850 2GB gpu and put her in, he has 500W PSU. Games like League of legends and Life is strange went pretty good, then in loading at the beggining of GTA V computer just restarted and kept restarting every 3-5 seconds until we turned it off. Now PC won't show bios and there is no beeping, just black screen. Someone maybe know what happened? is motherboard or cpu fried?

BIOS may be borked ... Try resetting CMOS... how to will be MoBo specific but instructions are in your manual.

We tried to remove cmos baterry and return it back, didn't help

PSU make and model? LoL and Life is Strange would not have pushed the GPU hard. GTA5 would have been the first time that 7850 and the CPU at the same time cracked themselves up and loaded up the PSU.

There are loads of manufacturers which slap a "500W" sticker on a dodgy 250W PSU. It could well have failed, hopefully just damaging itself in the process and not any of your gear. Have you got another PSU you can pop in to test (make sure it's capable of running the 7850, and don't fire up a game unless you're sure it can handle the load... but you just want to see that it boots).

we tried another PSU, i dont know model but i am pretty sure it says thermaltake, modular, 550W gold, didn't work, cpu fan is spinning, gpu fan starts spinning then stops, then after 2 seconds start again and stops again, we tried integrated gpu also and it didn't work either.

Well this is not looking good then. It's likely you've had a serious hardware failure.

Disconnect everything you can. Take out the graphics card, all but one memory slot, unplug all SATA drives. Use the PSU that was NOT in the system when the PC died. You just want the absolute bear minimum you can to get into the BIOS. Try booting into the BIOS with that. If that fails, swap out the RAM with another DIMM. If that fails... you've eliminated everything except CPU & Mobo... that's bad news.

We found another motherboard and plugged all gear from the one that didn't work and it worked, there was beep and screen, but it didn't show desktop because there was no HDD. So we plugged HDD and now it doesn't show screen again and no beep, I have no idea what is going on.

And you left out out for 20 minutes before putting back ?

Different motherboard often equals a full OS reinstall.

You're trying to change too many things at the same time, and not finding the actual issue.

We tried CPU, PSU and GPU on other PC and it all works, I assume motherboard died, tomorrow we will try piece by piece on the mobo where it worked before we put HDD, thank you all

Again, you can't make assumptions when MoBos are swapped. Imagine your car with a chip that controls ignition timing, fuel mix, and everything else and then you swap out the 6 cylinder Ford engine for the 8 cylinder Chevy. If it don't start, does that mean the engine is bad or does that mean it's never gonna start with the incorrect fuel mixture and engine timings.

Back in 1993 I wrestled with a "won't boot" problem" for 4 days. Turned off, used jumpers to reset CMOS, must done it 20 times... gave up Friday and turned off machine ... figured Id call TS on Monday, turned on machine (monitor was flipped on) and came back from the head and found my 2 year old playing Jerry Lee Lewis on my KB. Turned on monitor and found Windows desktop sitting there waiting for me.

Tech Support said "chips may hold data until charge on chip completely dissipates. may take 20 minutes". So now 23 years later, tho BIOSs have changed drastically, If i gonna bother to yank a battery (if MoBo has no rear switch), I leave it out 20 minutes ... it has paid dividends .. rarely but it happens.
