Hi so I'm not good with computers but I bought one over a year ago because I was starting to get really into PC gaming. I bought all the parts and had it assembled by a company called iBuyPower and ever since day 1 it has experienced very low frame rate in all my games and it crashes QUITE frequently. I had a very busy year and was not able to hound the company as much as I should have. I did end up sending it in once, and they held onto it for about 5 weeks and all they did was replace the hard drive and video card. This didn't make any difference. Now my warranty is up and they wont help me, so I'm hoping some experts can give me an idea of what's wrong or how to find out what's wrong.

As FAR as specs go, I don't remember it all but I'll post them if I can find my order summary. I do know I have 16 gigs of RAM and the video card is a Nvidia GTX 770. Also the power supply is 850 watts and my tower is not overclocked. Yes, my drivers are up to date. Lowering the in game graphics also does not improve my FPS. The FPS starts off kind of smooth, around 40-50, but if anything exciting happens in a game (attack animations, a second or third person on screen) it just falls to around 10-15 and stays there until things settle down. I've experienced this problem in ALMOST every game I've played, most are multiplayer. This includes Guild Wars 2, LoL, Heroes of the Storm, Dota 2, Serious Sam, The Old Republic, Neverwinter, Borderlands 2, Neotokyo, Diablo 3 and Gary's Mod.

When the PC crashes, it does not auto-power down. My screen and mouse cursor simply freeze, with the computer still running, and my keyboard locks up so I can't do anything other than hold down the power button and force a shut down. There isn't really a pattern to the crashes, but I deal with at least 2-3 on a DAILY basis. Sometimes the crashes are immediately after a previous crash, and sometimes they are hours and hours in between.

The FPS drops are, for whatever reason, not present at all in: Dark Souls 2, Smite, Hearthstone, and single-player steam games like Bastion and Valdis Story. However I have still have to deal with the crashing in all of these games (except for Hearthstone, which shows no sign of either problem). So please, if anybody has an idea of what's wrong, tell me. Help me out here. I'm exhausted of this computer, and it's barely lasted a year. These issues are ongoing from the day it arrived at my doorstep, and I received virtually no help from the ones who "expertly" built it for me. And if this topic is in the wrong forum, please tell me and I can take my question somewhere else. Thank you for reading all this, please help me, I'm desperate.Without specific details from the event log, it is just guess work.
Check the event log and see if there are recent reports of failures.

The above is for Windows 7. So I'm not entirely sure what all this stuff means but I did check the event log. There are over 3,200 errors/warnings listed since my PC was turned on for the first time. Anything in the log listed as "critical" I'm assuming is a crash, and the source for all of these "criticals" is "Kernel-power". The source for virtually all of the "errors" are either "Load Perf", "Application failure", or "Service control manager", with some other various things peppered in. Again, I have no idea what to make of this information.
