Long story.. My PC is 4years old HP Slimline 3505. I was trying to install a clean version of Windows 7 from an actual registered Windows 7 DVD. It would hang at the completion of Install (for 12 hours) I did a hard restart and tried to install again. This time I got a "Missing Boot mgr" error. After a day of many attempts of re-installing and different methods of booting no luck. I performed a hardware diagnostic. The results were that I had a bad or faulty memory stick. i then open the case up to see if i was capable of removing the RAM myself. I decided that i wasnt tech savy enough to remove the RAM. So i put the case back together and plugged it back in.
Now i have no video output or sound. the power supply still functions because the fans and lights still power on.
So do i need a new motherbboard?
Did i do something wrong when i opened it? Was there something i might have touch and fried it?
If any one could give me some direction that would be awesome.
P.S. I have tried to power on the PC with a single stick of RAM. Same results.
I used the windows compatibility software and it said it was ok. But a month after upgrading to Windows 7 my PC would go into comas instead of sleep mode. That is why i was trying to install Windows 7 Clean.
But I am trying to execute every option with in budget before i give up and buy a new PC. I mostly used it for google-ing and youtube-ing.
