So i have had this computer for about 2 years. Everything worked fine until a couple of weeks ago when my vid card died and later found out it was the mobo as well (i put in a different vidcard and the mobo fried that card as well. the capacitors visibly blew on the card).
So i replaced both the vidcard and the mobo. (biostar G41-M7 and MSI 9800gtx+) and everything is working fine. I can play games again with no lag or anything.
Problem is...sometimes when i push the power button to start the computer. All the lights and fans turn on, but the computer doesnt start up. Nothing is displayed on the monitor and i dont hear the harddrive working to load windows.
I have to shut it down and turn it back on and then it boots normally. (this happens about 40% of the time)
WHAT is this? is it a funny mobo setting? or is the problem actually my PSU (was that the thing that fried everything in the first place?)
ok so played around in bios...now the computer has been turning on normally for 4 days in a row. i turned off the on-board graphics card and turned on PnP OS... its working YAY
BUT! today while playing a game. it froze for a second and when it unfroze...the graphics were all messed up. textures where all over the place. structures in game totally disappeared. what might THIS problem be?
Is the driver for the graphics card up-to-date? I have a GTX-275, and on starting the computer, the graphics driver stops working on one of my programs, screen blacks out, and the graphics driver resumes exactly after 60 seconds. After that everything is fine until I shut down at the end of the day. This happens every time I start the computer. Minor inconvenience, so I don't bother about it (I did update the driver, but the situation worsened in my case, so I went back to the old driver).
This happens only on my Win 7 64-bit computer, not on my XP or Vista computers.
I don't know whether this will help in your case, but it is worth a try. Backup everything before you experiment.
Re-formatting and installing a fresh copy of windows on the machine would be the ideal way to go. Keep in mind that you will have to re-install all your programs if you decide to go this route. Yes, after you re-install the OS, you must do a complete (full system) virus check as well as spy program check.
Another option is to utilize the RESTORE function from "Backup & Restore" (Control Panel) and restore the computer to a known good configuration date. Then run the anti-virus and Spybot programs. Sometimes this may not be suitable if the computer backup and restore function does not go far enough back in time in order to obtain a 'known good date'.
the video card is messed up... in bois it is giving me random artifacts and the screen doesnt look correct
but when i go back to onboard video everything is clear and fine. ( i dont have another vid card to test in the mobo slot)
so im assuming the replacement vid card that MSI sent me is dead...yay
Your assumption is correct! It is not unusual for an entire manufacturing batch to be defective - all it takes is 1 bad component on the board. That's why they have serial numbers so that the defective product can be recalled. (Remember automotive recalls?).
Just make sure that you get a 'known good' video card and then install that card. There is also the possibility that the video slot is defective. If you have multiple slots, try a different slot.
