CSL Posted January 16, 2013 Share Posted January 16, 2013 Hey Guys and Gals, Heres the story. Last week there was a power outage in my city. My pc was on at the time (plugged into a suge protector) when the power came back on and I restarted the computer. No video. Heres where it gets weird. I checked both monitors by connecting them to my laptop and they work. I replaced my graphics card and still nada. I am able to connect remotely to my pc using team viewer and everything seems to work fine. After putting back my original graphics card I even updated the drivers and still nothing. So basically I have a working PC with no video. Here are the specs for my PC cut and pasted from Speccy: Operating System MS Windows 7 Home Premium 64-bit CPU AMD Athlon II X2 250 18 °C Regor 45nm Technology RAM 4.0GB Dual-Channel DDR3 @ 535MHz (7-7-7-20) Motherboard Gigabyte Technology Co., Ltd. GA-770T-USB3 (Socket M2) Graphics @ 1024x768 Generic Non-PnP Monitor @ 1024x768 ATI Radeon HD 5570 Hard Drives 488GB Hitachi Hitachi HDP725050GLA360 ATA Device (SATA) 32 °C Optical Drives JYDEL H27WL63 SCSI CdRom Device HL-DT-ST DVDRAM GH22NS40 ATA Device Audio Realtek High Definition Audio Any help would be appreciated.

ajnl Posted January 16, 2013 Share Posted January 16, 2013 Something wrong with the motherboard maybe. Have you tried another PCI-E port for the video card? or is there only one? Quote Link to comment Share on other sites More sharing options...

I only have one PCIE slot, but I tried putting in an old graphics card into a different PCI slot and it didnt work. Quote Link to comment Share on other sites More sharing options...
Ol Smoke Posted January 16, 2013 Share Posted January 16, 2013 It is in the chipset on your motherboard. I have seen this several times. There is a chipset on your motherboard that hands off to the video card. This chipset is very subseptible to voltage spiking. There is nothing you can do except replace the motherboard. To keep WIndows from having a heart attack, try to replace with an exact duplicate. Quote Link to comment Share on other sites More sharing options...
Masa_1964 Posted January 16, 2013 Share Posted January 16, 2013 I would start from power unit. And then move to mb. U can measure also outputs from power unit while it on motherboard and power on. Check also if there is separate fuse on Power unit. Masa_1964 Quote Link to comment Share on other sites More sharing options...
General Posted January 16, 2013 Share Posted January 16, 2013 (edited) It is in the chipset on your motherboard. I have seen this several times.

To keep WIndows from having a heart attack, try to replace with an exact duplicate. This, or just do a new windows install when you change the components. Or if youve got the cash, upgrade the system cause the OP is running some old hardware. I would start from power unit. And then move to mb.

It wouldn't be turning on if the PSU went bad, or doing other flaky things. Also, if it happened to short the GPU power connector, it would have like totally blown the connector, or failed the POST test/ burnt into the GPU. Situations like these are unfortunate and why I recommend getting a UPS (Uninterruptable power supply). UPS' will save your machine, as they are like giant batteries in a sense, that, when power goes out, you will have X amount of time that the PC is still running to shut it down without it crashing. Good UPS' like the one I have, has software you can download that can shut the PC and related accessories off automaticallywhen the battery in the UPS has a certain amount of battery left.

CSL Posted January 17, 2013 Author Share Posted January 17, 2013 Thanks for the input guys. Its definitely not the power supply because the computer is actually working fine. I logged into it remotely to check. I definitely dont have the cash to upgrade at the moment. I also think it might ce the chipset on the mother board. UPS is a great idea but the surge protector should have done its job. Quote Link to comment Share on other sites More sharing options...
Narug0 Posted January 17, 2013 Share Posted January 17, 2013 Same happened to me with, my old pc, m2n68-am se + athlon x2 7750, power outage and booooon when I tried to start after energy restored no video. Think i had luck, despite worked only after change power supply and still was running like your pc, hd running, lights power, cooler video card and no video, but not connected with any remote desktop. And in this computer m2n68-am se + athlon x2 64 5200+, power outage lot of times .But I suspected from update MICR0S0FT about k3rn3I, in both computers happened after this update needing only restart. Next time u connect with team viewer check what video card is working. (onboard or your ATI Radeon HD 5570), your monitors r plugged in power supply?

I'm curious because I have one that looks pretty much like an extension cable with 2 lights on it. Still not sure if they are reliable whatsoever tho.

General Posted January 17, 2013 Share Posted January 17, 2013 Surge protectors should not be relied on to completely protect a PC as a sudden loss of power can be as damaging to components as a Spike in voltage Quote Link to comment Share on other sites More sharing options...
