After 2 weeks of tweaking things on this system I have to ask for help.
My system: Acer Aspire X3400 (It's a stock computer no custom parts added)
Processor / Chipset -AMD Athlon II X4 635 / 2.9 GHz
graphics card(onboard) NVIDIA GeForce 8200
RAM - 4 GB
Hard Drive - WD 1TB
power supply: liteon ps-5221-06
OS: Win 7 64-bit
Here's the backstory I bought this 3 or 4 years ago for my parents to replace their old gateway from 2001. After a couple months it started to BSOD once in awhile. I figured out that it was overheating because it was set up against the wall. I decided to take it apart to clean out the dust. At the time I didn't really know anything about computers so please forgive me for my ignorance and the cardinal sins I committed. I opened up the case, removed the heat sink, looked at the processor and thought, "damn look at all that dust thats caked on the processor" Of course this wasn't dust but thermal paste. So I wiped it off put everything back together and it started to BSOD again. I assumed it was junk and we bought another pc but my curiosity got the better of me. I thought what if i put the heatsink fan on backwards? sure enough I switched it around and the computer started working again. So for the last 2 or 3 years I've been using this pc for streaming movies and tv over my LAN. About a month ago I decided to change it up. I decided to install linux ubuntu 12.04 it worked fine for 2 days then I updated the video drivers and all hell broke loose. I would turn it on and the video would start to go out the screen would freeze and the image would be cut in half discoloerd blurred and glitchy. Since then I uninstalled ubuntu and went back to Win 7 I still was having the same problems except it occurred less. so i decided its about dam time I put some thermal paste on it. it went from running at 55 to 60C when idle down to 35 to 40C when idle. After that it ran fine for a week no problems what so ever. then the other day it wouldn't start up right. After pressing the power button there would be no beeps meaning it failed POST. It would keep going in a loop restarting and never getting past POST. I started looking at it again the last 2 days and both times in the morning it wouldn't start up. It kept looping off, I would take it apart and put it back together it would start looping again and eventually it would get past POST. Then it would crash a few times during windows startup, reset and eventually work fine. I've currently had it on and have been using it for the last few hours watching movies and browsing the internet.
So what do you guys think? is it the video, processor, motherboard, PSU, that is causing the problem.
here's a link to video of one of the crashes
