Ok, I consider myself pretty good with computers. I have fixed my parents, friends, strangers computers for years now. This one though is starting to worry me. I am going to go into great detail, in hopes someone can help me out. Just recently ( Nov 10, 2k5 ) when I was playing CS:S (after new steam platform update), i had been playing for about 45 minutes, then my monitor went to standby mode, and looping sounds happened for about 15-20 seconds then stopped. After nothing happened for awhile, i restarted and while in post it said my overclocking failed (2.0 to 2.2, A64 3200+ Claw), I ignored it and went into windows. Started to play CS:S again and within 30 seconds same thing happened. I tried to restart again but monitor did not come on this time, and 1 beep occured. I then shut down my comp completely then turned it back on. This time no OC'ing message and everything was going normal. I tried quake 3 for a min or two and everything was fine. (I thought all this was happening b/c of Steam, but its in almost all of my games). I then tried different games such as Painkiller, UT2004, Warhammer: Winter Assault, HL2 Lost coast etc., all made monitor go to standby (with the sound looping issue as well) when entering. So, ok must be a driver issue right? Nope. I updated my vidcard drivers for my 6600GT AGP to newest (81.85). Still no luck. I updated my videocards BIOS, no luck (and took away my temp monitoring ). Then I reinstalled DirectX 9.0c, no Luck, turned my Video card settings to default (500/900), no luck. I even set my BIOS to all default. As you guessed it, no luck. This ONLY happens when I try and enter a game. I can browse internet, use MS Office and defrag and listen to music/watch movies all day. My temperatures for my cpu/hdd/vga are all within normal temps (cpu 35C idle, vga 43C idle, HDD slightly warm to touch) I also did system restore as a last resort but of course didn't work out. I really don't want to format, as that would take a LOT of time to backup everything. Anyhelp would be REALLY APRECIATED. Thanks for taking the time to read this.
