Here is the deal... about a month ago my computer started acting weird, I press the power button and the monitor (AOC 22f 1080p) will stay with no signal and the button orange and if I restart or turn off and back on several times it worked dunno how... then it got to a point that it was not even starting after trying many times, and at some point I decided to remove the ram and put it back in, hoping it wasn't properly hooked into the slot and when I did, and powered on, it beeped with a long beep then powered off by itself and repeated the thing about three times, i.e. turn on, beep...off beep...off beep...off all by itself then again with the orange button all the time, I thought it was a ram issue so I ordered a new set of ram memories (Corsair XMS2 4 GB (2 X 2 GB) PC2-6400 800 MHz 240-PIN DDR2 Dual-Channel) I opened and inserted the new set of RAM and it started working just fine for two days...then I wanted to do a backup of my files on DVD´s and noticed that my cd/dvd burner was opening as usual but not being recognized by the OS(windows 7 Ultimate) so I turned it off, went into the BIOS and checked that it was there and it was, couldn't make it work from windows device manager so I turned it off and decided to change the SATA port to see if that would get it fixed, turned back on and guess what??? no signal and orange button again...I have checked the ram with another pc and they work, I have checked the video card (Radeon 5770 - ATI HD 5770 GPU - High Speed 1024MB DDR5 - Microsoft® DirectX®11) with another PC and it works too, the processor(Intel Core 2 Duo E7500 2.93GHz, 3MB Cache, 1066MHz FSB, Wolfdale-3M, Dual-Core) as well and nothing...
I have turned it on while opened to check the inside and the processor fan works fine, the HD sounds normal, the only thing is that sometimes when I power it on I get long beeps and short beeps at some point (I´ve tried looking what does long and short beeps means for the Board: MSI P45T-C51 and couldn't find it, maybe that's my problem) I have even thought that it could be an electric problem other than a hardware issue, I got it to a technician and the dumb [bleep] told me that the video card is not working and that he tested it and didn't work and I have tried it on almost all of my friend´s PCs and it works... so what else could be?... there is no dirt inside my pc, is even cleaner than my room...aaaaaaaahhhhhhhhh.... I don´t know what to do. please help!!!
