Such as wipe off the heat sink compound, apply new and check the fans?
Well my friend baught a new pc for about a year ago. And he baught it in parts, so he could get the parts he wanted. Well and after he got the parts he assempled the pc and installed windows 7
In the start everything went well with playing games, with no lag at all. (He mostly played Skyrim) But after a while he got tired of Skyrim and wanted to play something else. Here is where the problem come. Almost every game except from a few, makes his pc either crash, freeze or lag. Me that had a worse pc could run the same games with higher setting with no problems, what so ever. And so i started discussing this problem with my dad.( which helped him pick the parts our, and also we build a lot computer and helps when someone got a problem) and so we discussed and found some selutions. But when i tried them, they didn't do any difference.
We tried:
Increasing fan speed.
Reinstalling windows 7
Running the game from another hard drive
Installing Winows 7 on another hard drive
Testing his videocard in my pc. And than i could still run games better than him.
And also restarting the CMOS.
And so i come here and post this for more expreienced people to read and to hopefully help us out. And if anyone could have a selution, we could then finally play together in other games than minecraft. And he also has no problem buying new parts, but he doesn't want to but new parts in vein
His specs:
Nvidia Geforce GTX 560 Ti
AMD FX (tm)/4100 Quad-Core prossesor 3.60 GHz
8 Gb ram
Gigabyte ga-970a-ud3
