Question (URGENT HELP) PC does not detects monitor...

[themisPlayer]

Hello there! I was using my PC as always and while I was searching something on a browser my Computer bugged/crashed and restarted. I expected it to just to turn on and continue normally but no luck... I heared the Windows 7 opening sound effect but the Monitor didn't detect any device.
My Monitor doesn't have any problems and I check and changed the cable (and also tried my mac book) and everything with the monitor is working smoothly [Monitor : LG 25UM58-P]
I tried more that 20 different ways of fixing this.
Disconnect all cables and press the start button for ~60s
Removing the graphics card and cleaning it and pluggin it again
Relocating the RAM
Change the small battery of the MOBO
And most of the ways I found online..

-CPU : Intel i7 870
-PSU : Thermaltake 700
-GPU : Gigabyte GeForce GTX 650 Ti Boost OC WindForce 2GB
-RAM : 4x4GB 1600
-SSD : Samsung 250GB
-HDD : Seagate 2TB



(The wrost part for me is that I have all my files that I need for this Thursday on it for my Uni..)
If anyone could help I would appreciate a lot!
Thank you!

Can you boot without the gpu?

Yes the PC seems to Boot normally (also with sound effects of windows),
BUT some times when I press the power button it is just Booting (opening the fans etc) and at the first second everything shuts down and restarts after 2 secs
ALSO some times when I Boot the PC it "seems" to boot normally and after 1-3 minutes It shutsdown and restart..
Unfortunately my MotherBoard doesn't have any Internal GPU so I can't really test it.

Your Monitor has 2 HDMI inputs - Have you tried both of them?
- I am sure you would have tried by now but doesn't hurt to confirm.

Which motherboard do you have - are there any diagnostic LED's or 2 Char code display on it?

If you monitor is working fine with macbook then
1. Boot into safe mode by pressing F8 every 1 sec

• if display turns on then graphics driver is a problem
• if not then u need a new gpu card

Your best bet would be borrow a monitor n cable from a friend to test.
