PC virus affecting motherboard/bios?

By mommeeof10 ·
I took my daughter's hp s5713w to the shop for repair, as it will not display anything on the monitor. They thought it had a virus, stated I could pay them $170 to save her data and reinstall windows 7. I chose to reinstall windows myself, but could not get her pc to display anything to be able to access dvd. I used another pc for imaging (Dell Inspiron running vista home premium). Afterwards, HD seemed to be working fine on the imaging pc. Her pc still does not have a display after reinstalling hd, pc used for imaging has developd similar issues- interested speckles of color blink on monitor, problems follows both pcs if connecting to another working monitor. ARGH! Help! Can't afford to have a "professional" repair these pcs, still have 9 kids at home.

I'm having a little trouble following along, but I think basically:
* Your first PC stopped displaying anything on the screen
* Your second PC has starting having monitor issues after you plugged the hard drive from PC #1 into it

Is that correct?

This sounds like hardware problems to me. You stated the problems are the same for both PCs when testing with a known-good monitor. That means the fault is with the computer. Something is really shot with the first PC that gives no image at all. Do you hear the normal 'beep' a couple of seconds after booting this computer? If so then yeah, it's probably a video card issue. If you don't hear any beeps (and you used to) then it is going to be a CPU/power supply or maybe motherboard issue. You can try swapping things out if you know how and have spares. If not, you may be better off putting your money towards a new (or second-hand) replacement. If you hear multiple beeps after turning the PC on it means something is wrong with the hardware, and the number and sequence of beeps tells you what is wrong. You can look up the beep codes in your motherboard manual to find out what the issue is, although you may be better off taking it to a good computer store as it needs a little knowledge, and probably some spare parts to test with.

The second PC sounds like it has a video RAM issue. This will often manifest itself with dots or squares on the screen (and these may move around). Double-check that the cable going from your PC to your monitor is plugged in firmly and replace it with a spare it you can. Next, I'd probably update your video card driver. If you have a dedicated video card then open up the PC case and ensure it is pushed in firmly.

I doubt the above steps will fix the issue. As mentioned earlier I suspect you have a video RAM problem. So if the above don't help buy yourself a dedicated video card. They are cheap - see You will need to plug it in inside your case, then boot into Windows and install the driver software to make it work. This (and most of the above troubleshooting steps) can be hard for someone that doesn't know computers much, but do not need a professional. If your kids go to school with a kid that is good with computers then they should be able to get it done.

Whether you do it yourself or get help, I suggest do a little homework first. Make sure your computer can accept an addin PCI express video card. And if your PC does not already have one it means the video card is using system RAM, so the system RAM may be faulty. You can try removing sticks one at a time to see if the problem disappears. There is software you can use to test (Memtest 86 for system RAM, I can't remember the name of the tool I use to test video RAM).

I'm wondering if the power surge we had during a thunder storm a few months ago could have started the problems? The kids plugged everything back in during a lull in the storm. Lightening hit the phone line coming into my house from the street. The kids were facinated to see the sparks travel down the phone line. The surge took out my dsl modem, router, a motherboard, the motherboard integrated network cards on both these pcs and an 8 port hub.

We have no graphics displayed on either pc currently, can not see what I am choosing when going into set up/bios, so would I be able to add a graphics card? A friend suggested if I had a virus on first pc, the only thing he thought it could do to affect the motherboard is to maybe have overclocked something, causing something to burn out?

I may take her pc back to microcenter, as it has an extended warrantee on it, which would not cover viruses and reinstalling os. Other pc is almost 4 years old, it is probably not worth my time to troubleshoot it further?

I can usually figure out pc problems, but this one has me stumped. Time to get out my How PC's Work book?

After unplugging both SATA drives, second pc will boot off vista dvd and get into the restore options on dvd. I then plugged in both sata drives with pc on. If I mess it up, no worries, as it already does not work...

I think I have identified issue with pc used to image harddrive. When booting off vista dvd and running recovery, sometimes the motherboard does not see the hard drive. I wonder if the motherboard or hard drive are going? After multiple reboots from dvd, finally saw the hard drive, and ran a restore. Now, each boot gets me to the screen where you can choose safe mode, safe mode with command prompt, etc. I can choose start windows normally, get to the log in screen and log in.

Lightning. Protection

Yes there could be a corelation with both PCs failing shortly after a strike entered the home. I had the same thing happen although the strike didn't get past the UPS, surge protection saved the peripherals but the PCs exhibited flaky operation. One a DuoCore home build and the other an HP unit from a car dealer(P4). The home build failed to recognize any hard drive and the HP went nuts with the onboard NIC and tied up the router. Both hard drives were recovered intact and data was easily moved to a new PC(WIN7) with an external enclosure and USB interface. Surge suppression is important but when a strike enters the home, especially the phone lines, as few suppressors include them in a filter or pass through connection.
