About 4 months ago i built a pc for my brother and it has proved to be a nightmare from the word go. After a few initial problems I managed to get the computer to work perfectly until last friday. He said his computer was going into sleep mode after 5 mins (another matter) and he also opened the case and found the fan and heatsink had dropped onto the graphics card, he was able to reinsert the heatsink (standard intel LGA 775 heatsink) but only the exhaust fan was working.
I took his computer home to fix it and install a new heatsink (Thermaltake Golden Orb II), during which i accidently dropped the heatsink onto the motherboard where it landed on the pci slots D:. I finished installing the heatsink i reconnected all of the power and hardware i turned on the computer only to find myself back at where my brother was on friday. I noticed the following as well:
-HDD Light on but not blinking
-No BIOS beep code
-Intel E4400 cpu
-MSI G33 Neo
-Coolermaster Centurion5 case(430w PSU)
edit: forgot some information.
