Bad mobo, or...?
Ok folks let me give you a run down of what has been going on with my other computer. I opened an email from my sister that was time stamped at like 3am. Very odd since she works at like 7am, but i opened it and it was a link to a page that couldnt be opened. No red flags were thrown up yet, but a few days later my mouse started to give me fits. It would lag intermittently and finally lock up and only a restart would remedy this problem.
Then my monitor came up with a no signal display and has not showed any kind of graphics from windows. Neither the vga port on the motherboard or in the aftermarket graphics card installed in a pci slot work either.
Thinking I might have a virus or other "attack" on the computer, I updated and ran the following programs: AVG, Avira, Malwarebytes, Spysweeper, and Hijack this. These turned up nothing.
My mouse and keyboard are wired ps/2. I uninstalled the driver and let windows reload them. Nothing.
Swapped the power supply with a 100 watt lower rating( had a 450-swapped to an extra 350 I had laying around) also to no avail.
Finally I pulled the hard drive out and plugged it into the computer im typing this from and formatted it. Sata to usb cord was used for this. Reinstalled the hard drive and put in my recovery disc only to find out this did nothing as well.
I'm at a loss here and my next guess is that the motherboard is bad, but i have never had one go out and aren't sure of any telltale signs.
Any input would be greatly appreciated. Thanks!
