The computer would turn on but no signal going to the monitor. Sometimes, the computer would turn on and there was no signal going to the monitor, keyboard and mouse. I run a FULL SCAN with Kapersky antivirus an there was no virus in any of the 3 hard drives. Finally, the other day everything was fine until I tried to connect a pair of headphones to the back of my desktop. When I was connecting the headphone I kind of push the desktop with my elbow and I lost the signal to the monitor. I adjusted the cable monitor but still no signal. I have not been able to use my desktop for 2 weeks. What could be the problem? What should I do?
This are my components:
1) GPU : PowerColor PCS+ AMD Radeon HD 7870 Myst. Edition 2 GB GDDR5 DVI/HDMI/2Mini DisplayPort PCI-Express Video Card AX7870 2GBD5-2DHPPV3E
2) PSU: EVGA SuperNOVA 750 G3, 80 Plus Gold 750W (New, I changed the old one because I thought it was the problem)
3) Processor: Intel Core-i5 3350P Quad-Core Processor 3.1 Ghz 6 MB Cache LGA 1155 - BX80637i53350P
4) RAM: 16 GB
5) Motherboard: Gigabyte LGA 1155 Intel B75 SATA 6Gb/s USB 3.0 Micro ATX DDR3 1600 Motherboards GA-B75M-D3H
I had it check by 2 people, one is a friend that used to build computers a long time ago and the other one is my gamer friend that build computers as a hobby:
Friend .- Said the PSU was faulty. Then he also said there was a problem either with the processor or the connection of the motherboard to the processor.
Gamer Friend.- I gave him my computer. Told me connected his PSU and the machine worked. Dediced to buy the new PSU you guys see up there. He reinstalled Windows 10 Pro. When I took the computer to my house, it immediatly started presenting the same problem (it did not work even once). He came back to my house and proceded to disconnect and reconnect the GPU. Then he disconnected GPU, Sound Card, RAM. Nothing, the computer would turn on and off, sometimes it would stay on just a little bit longer. Long enough to see the BIOS screen. Then it would turn off. The he tried to reset the bios with a paper clip. For a while it worked, the machine stayed on. We left the machine on for 10 minutes and turned it off. Again the problem of turning on and off. He does not know where the problem lies because apparently my motherboard does not have the small speaker that emits sound to tell you what the problem is (the guy I mentioned previously said the same thing). In the end he told me "Man, I do not know what happened. In my house it worked with a new PSU, everything was fine. I reinstalled everything. The only thing that I can tell you is that I was lucky and you need to change motherboard, CPU and new RAM." He recommended me buying this
16 GB RAM - The cheapest I can find DDR4.
Kind of bum out the computer only felt short of 5 years. It only lasted 49 months. When I built it, I was planning for it to last 10 years, and keep update with only a new GPU. Getting married right now, paying for a house, honey moon etc. Did no want to spend money on my hobby.... I am not a big PC gamers. Only play on PC for certain firs person shooters (was planning on buying Wolfenstein 2, Prey, Rage 2 and Doom Eternal) and any RTS released by Paradox. However, I did love working on my 27" ASUS led monitor instead of my 14" Lenovo laptop. I do not know what to do now. Maybe just buy an ultra dock to connect the laptop to the monitor? I mean, even if I fix my desktop right now, I will not be buying a new GPU right away, I would be using the old one. The GPU right now are really expensive.
