Hey guys im new to the forums although I've been a visitor for ages now. Anyway , Every time i play a game such as Call of Duty 4 (multilayer) my PC sometimes will get some Fps drop occasionally and / or just do a Warm Boot Restart. Now Ive put in new power supplies its a new gfx card ive tested a lot of the hardware and no matter what i do it wont work for me. These Random restarts are starting to get very aggravating and i was hoping that someone on this forum could be kind enough to hopefully shed some light on my problem. Now My suspicion is that my pc could be overheating, however i have a temperature gauge and its all in 30's-40's idle and 50's under load. Despite this its the kind of re boot that would occur because of overheating. Anyway I no some of you guys have experience with this sorta thing so i will upload my miniDumps from after the Restarts and will also post my system specs below. Really appriciate any help .
