Clarification Request
New? Just built? Warranty?

The story here is incomplete. Some of these won't work until the BIOS is updated and for this model you see an Intel CPU with onboard video so you don't need the video card yet.

But did you just slap all the boards and parts in at one go?

That's not how to start off building PCs. You start with minimum parts to see what's what and then update firmware before the OS so you don't have to do that for a long time.

So my PC has worked perfect for a long time, but when turned my pc on an played some of my games it soon began messing with one of my screens, so i decided to restart my pc... After that it didnt work.

Update: I have gotten my pc to stop shutting down, but it wont post

No BIOS = dead PC

So it's time to do the usual strip it down to least number of parts. You don't need drives, or the video card. One stick of RAM and if that fails, the fault is in what's left.

But over the years I've seen such traced to bad memory sockets, folk that erased the connections off a stick, fried sticks due to overvolting and a few CPUs that didn't make good contact in their sockets. In other words, it only tells you so much but not exactly.

Re: boot loop

Does it start Windows before it shuts down, or is it still in the BIOS? Most likely it's a hardware issue, but if it happens running Windows already it could be a Windows issue also. An easy test is by booting from a bootable CD.

Forget BIOS update for nowios

I wouldn't even try a BIOS update until you resolve the system not booting or getting to be able to correct the issue. However, if it is a bios issue as the of the problem, then you're pretty much stuck. You wait too long and there is a real problem based on h/w or similar. I can only suggest you tear it all down and rebuild using separate parts or "test bed" testing 1-part only and check results. Since, you stated gaming, that too can come into the picture, because you now have found the weakest link of your system. generally speaking, you may have power issue or broken competent. You stated earlier you resolved the rebooting part but not how. If in fact you entered the bios to NOT reboot during start-up, that gives a clue of some h/w fault. But now, you can't display the bios offers that it is a low-level problem so basic that h/w again maybe the cause.

So again, I wouldn't fool around with the bios unless it remains up and running as a basic(minmium) PC. If you try to update and it fails during this process, you now have a door stop.
