It has been 2 years im using this PC of mine... My configuration's are:- MSI 945GCM7 (mother board), Intel DUEL CORE(2.20) (processor), 80GB SATA HDD, 1GB RAM, And 1 GIGABYTE GEFORCE 8400 series PCI express. when i added this graphics card 2 my PC. I'hv faced many problems while playing any high/low graphics games. I'hv already asked 4 help about this matter here at TOMS HARDWARE forum but nothing helped me solve that problem.......... So what i did was i removed my PCI and tried to play low graphics games using my built-in VGA drive......... but sigh............ now when ever i try to play something it runs for a while but after about 10-15 my PC restarts automatically........................ i just don't know what 2 do..................... PLZ who ever gets to read this Message please give me a solution to my problem.......... i will w8 for your reply...................... Thank you....
