a friend of mine was vacumming the dust from the computer insides and it suddenly wont start. what i mean is that the computer does have power, has lights but it wont go to post or wont even give a signal on the monitor. Actually the lights keep staying on e.g. the HDD is running, cdrom is reading..but the catch is...ALL of the lights are on at the same time and stay that way. What is wrong with the computer you think? i think the motherboard is dead. Well first i thought it was the power supply but then we went out and bought a new one already and it still the same. mobo is K7T TUrbo2 with a 2400+. Is it dead?
