So last night I was watching a video. Just as it was about to end, everything froze. The video stopped playing, there was no audio, I couldn't exit out of fullscreen, couldn't exit out of the program, couldn't open task manager, ctrl-alt-del did nothing, alt-f4 did nothing. So I held the power down until it turned off. Turning it back on, the screen said no signal detected. There was no red laser light at the bottom of the mouse, but the blue light on top means that it's on and connected. I waited a couple minutes, long enough for the computer to startup and reach the log-in screen. I typed in my password to see if it was my monitor, but the login sound didn't come on. So I'm almost certain that the problem is somewhere inside the tower.
After googling a while on a different computer, none of the solutions worked for me (I didn't try some, like taking out the RAM, restarting the cmos jumpers, etc, since I'm worried about making matters worse).
I've had no problems for the past few months since I bought a new graphics card. Everything has been working wonderfully. Just all of a sudden, it froze and stopped working. I have a computing assignment due in a couple of days and I'm really freaking out.
Also, on the computer I'm using now, I was using Codeblocks to code. But then Codeblocks crashed, and every time I try to open it it says that it encountered an error. A couple other programs are also experiencing the same problem. Am I cursed? For some reason it works again :/
Edit: I opened it up when I turned it on and everything was spinning, all the lights were on as normal. I turned it off and took out the video card and put it back in, cleaning out some of the dust from inside the comp and on fans and stuff, but didn't do anything.
Also, sorry for the long post, figured that the more information I gave, the higher the chance someone would know what was wrong.
