I recently repaired an old computer I had for quite some time, I had maybe 4 problems with it, One was that the computer wouldn't boot up, I swapped the old PSU for a known good one, this fixed issue 1 , issue was that There was faulty ram, I replaced the ram and didn't get the beeps, issue 3 was the cpu fan, I't didnt spin at all so I replaced it with a known good one, I booted the computer for the first 3 times and it worked perfectly fine, It showed the post screen, went to the windows xp screen, and was a little slow but I was able to fix the problem, but then 3 weeks later, I turned it on and the monitor didn't show anything, I tried it on a new monitor and it didn't work I tried again and it worked just fine, for like 5 minutes then the monitor went off again, I made sure everything was seated properly and that all cables were hooked up properly but still no results, I kept trying and it worked sometimes but then it didn't so I tried a vga card but still nothing and I tried this on another computer and it worked, then I tried one more time and the onboard vga worked but then out of the blue it went out again
, Ive tried allot of things but this seems to be getting out of hand for me and im trying to avoif buying a new mother board cuz im certain that can't be the problem, unless it's barely starting to get faulty...
any ideas ?
