Ok so i have 4 computers in my house, My desktop was running fine, Me and my buddy wanted to start playing Hellgate london, So i had to upgrade the desktop so it meet the minum requirments, So i went and bought a 512MB Vid Card, (/VisionTek/Radeon HD 2400 Pro) Installed in got the drivers, Got the game up and running, Played for 12hrs, On and off and had my computer freeze up on me 3 times, I went and got Speedfan, And it showed me that my 3rd sensor was running at 57-59C when i got to 60c it would shut off, My first 2 sensors where in the 33 C range, The third sensor was only getting hot when i was playing the game, And i noticed there was alot of dust in the CPU fan and front and rear exit fans, So i thought mabe if i cleaned the fans would cool it down a little bit, So i turn off the PC clean out the fans Pull the heat sink and CPU fan off the Prossor cleaned all that out and the other 2 fans, pluged it all back in and when i tryed starting the computer would start up and the immidelty shut down, I figured that i put the Heatsink on wronge and it was apply to my forse to the CPU, When i took it off the computer would come on, Not sure if all the way on but i no it would shut off imideitly like befor i finaly figured out how to get it on there where it would function properly,and come on, So i plug every thing back in, And turn on the computer and Now i get NOTHING, Expect a really loud screech comeing from the CPU area, Kinda like the sound a bomb would make falling from the sky,Just really high pitch, Mabe more like a Tea pot on the stove when the steam starts comeing out of it, Just really high pitch contuinsly getting louder, If i leave it on The Compastiors around the CPU start getting really hot and u can feel the heat coming off of them.Theres also a Burn smell comeing from the same area as the screech, So i took the heatsink off the cpu and that chaged nothing, so i started troubleshooting the problem to see if i could figure it out, Took the PSU out of the case to see if it was makeing the screeching noise, It waznt i took the new vid card out and used the On-bord Vid card to see if that was the problem and stil when i turn the computer on i get the screech and a amber light,And the amber light gose off after about 15secs,every thing seems to power on, Just get no signal to the monitor, no nothing, I unpluged the Fans from the MB to see if a fan was makeing the screeching noise, But after unpluging i still get the screech from the CPU area, (Kinda hard to get exact location of the screcch) so after i have unpluged the fans, and rulled out the PSU, I swaed out ram sticks and slots, Still no Signal/Loud screech and steal the smell of somthing burning,I then took out the CPU and fliped it over to find a Black spot about a inch wide in the center of the CPU, Not sure what the problem is, Never came across anything like this, The specs of my COmp are
Its a Hp pavilion 744v desktop
