Ok.. so about a year back, I bought this Acer Aspire as a computer for doing my school work and playing low demanding games. It came with a fairly good CPU (3.5 GHz i7 2600k) and a 3TB harddrive. Back then I thought that that would be great for games especially if I decided to upgrade the graphics card from the terrible nvidia 520 to a mid-range card. I ended up buying a Sapphire 6870 and an Ultra LSP 650w psu to run it.
A few months after installing it, the display would start shutting off then turning on with a message "Display driver has stopped working but has recovered" (or somthing like that). I found somewhere online that my BIOs may need to be updated, so I checked the Acer site and flashed the BIOs. The problem stopped.
Then a few months later, when turning the computer on. The display would not start and the monitor would act as if nothing was plugged in. I would turn off the computer then start it several times before it would start the display properly. After about a month of doing this... the problem stopped.
Months after that (starting a few weeks ago) both problems started. First I had problems with the display starting with the computer, then the display drivers started crashing. Along with those problems... my computer began blue screening every once and a while telling me to remove any new hardware or software dispite having the card for nearly a year before this happened. The other day, the display driver failed and restarted 3 times with in about 5 min before shutting down and not recovering causing me to have to turn off the whole thing. Recently, to get the display on, I have had to turn the computer on, leave it on without display for about 10-15 min after I woke up and had breakfast etc. then turning it on and off again. Of course I got tired of it and opened up my computer and replaced the PSU and Graphics card with the original, terrible hardware that came with the original computer. ( no more isssues are had with these peices so the problem is not from the CPU, motherboard etc.
These are the only causes to the issue that I can think of:
1. Could the PSU or GPU be broken or damaged
2. The case for the computer is not that big so some wires for the PSU could have been cramped. The computer was well vented enough to keep a good temperature but is it possible that a cord being damaged could cause such issues.
3. Could one of the latest Catalyst Drivers be the cause of the issues (seeing as how this only happens months apart, as updates tend to happen.
If you think that one of my theories my be correct or have your own with a solution, it would be helpful to know
PS. I live in a small city in Northern Ontario so there are only a few small computer stores that do not have any hardware that is useful or people who know what they are talking about... if I took my computer there, they would just try to sell me a new computer instead of offering solutions.
