Here is the problem. Every time I turn on my PC, it boots up but after a few seconds my monitor turns black and then I will see this message "NO VIDEO OUTPUT (below that) ENTERING SLEEP MODE". The PC seems to be running, but the monitor is off and the video card's fan (basing from my observation) seems to spin at 100% then halts back to like its usual slow spin. Without this problem before, my video card doesn't seem to do that. Another thing is the system is running normally, cpu fan, and other fans working. The only thing lacking is I cannot see anything.
What seems to be the problem? Just a back story, prior to this, I never had this problem. This started happening after I cleaned my PC. By cleaning I only mean doing a blower thing and removed the parts. Nothing more than that.
Heres's my specs for reference:
intel e7500
asus p5kpl am se
9800 gt sonic ed.
fsp 550w
OS: windows ultimate 32 bit
Here's what I have done so far:
1. Retraced my steps to check where I did wrong. I only touched the hard disk and video card. I used the blower which was sold from tech mall.
2. One time, I was able to get past the NO VIDEO OUTPUT message and I went straight to safe mode and did a factory reset. Problem solved, but now... its back.
Please give me some other advice as to why this happened or what could be causing this? Any tips on how to prevent this from happening again will be really appreciated. Luckily, just now, I kept rebooting the PC and I was able to post here.
