What Jakg said. Just unplug your PC and pop open the case. Unhook the power supply cables that go to the mobo and CPU, remove the little battery located on the board, wait about 10 minutes, put the battery back on, and plug everything back in.
Since I saw that Alien is wanting to base his system on a much higher end in another thread, I'd suggest going for an EVGA 780i, 2 9800GTX's (They scale in SLi MUCH better than 8 series cards) or a single card if SLi isn't wanted, a 700W+ PSU (SLI, 600 will do fine with no SLI), a Q9550 if you want a quad, and a WD Raptor to go along with the 500GB Seagate drive I suggested.
It was a while back in an LFSCAR race at Aston Club, driving an XRR. I had a pretty rubbish start, nailed the wall coming out of the chicane a few times. Got spun by another driver, had a hell of a time getting my car back onto the track, blew a tire around lap 45, and coming out of the final turn on the last lap, a tire gave out again and sent me into the sand, but luckily my car had enough momentum to make it through the kitty litter and made it to the line, finished 5th.
I should win an award for cramming the most crap into one sentence
Hehe, I love how it keeps the comedic style with radio commercials in previous GTA installments. Every scene has something bad happening to someone and/or the car
If you want extra cooling on an 8800GT, you'd be better off with an 8800GTS 512. The extra $40 or so for a cooler for an 8800GT would equal the price out with the GTS in most cases.
