Please help me.do i need to get any additional game card? if yes then which one? dont know wats wrong with age of empires,it runs even on celeron-833 with just 64MB ram. Experts plz suggest solution to my prob Thanx in advance

"some times my PC reboots while i m palying for no reason" Obviously there's a reason, you just have to figure out what it is. Have you reinstalled or updated your drivers? BTW, you really should have a graphics card for gaming.... http://www.intel.com/design/motherb...

yeah,i hav even reinstalled windows many times and hence the drivers also.but i get the same problem.is thr some hardware related problem?
