I recently added a new sound card and HDD to my computer.
The sound card was only purchased because a family member tripped over the wire connected to the audio port on my motherboard and broke the connection.
So in preperation for a new motherboard I unassembled the computer.
an exact timeline of events would be:
1. come home to find computers audio port in the condition stated above.
2. i unassemble the computer in preparation for a replacement mobo.
3. i remove every part including the cpu from the mobo.
4. i bring the motherboard in to be fixed but am given a cheap soundcard to install instead of replacing it.
5. i install reassemble pc and install soundcard (in my opinion carefully, i built the original myself aswell).
6. problems begin. noticed after about 2 hours of use
p.s i did not notice any problems prior to unassembling pc but did not subject it to prolonged use.
I can't recall it happening before I installed the new components, but I did not use the computer for more than a few minutes at a time during that brief
period in which I had no sound. It always happens after about 2 hours use, but it sometime stretches longer than that.
Since installing the new sound card and HDD my computer does the following.
Randomly the screen will go black and the system becomes entirely unresponsive, the fans and lights stay on. A reset is required. Sometimes this will
not work unless the computer is left for a while. (It just boots and freezes).
Randomly the computer will freeze and become completely unresponsive and a reset is required. (screen still on).
Randomly it will reboot itself.
Sometime the i am met with this message upon booting
"please enter setup to recover BIOS setting
CMOS date/time not set
press f1 to run setup
press f2 to load default values and continue"
The date and time are then found to be wrong in the bios.
I actually sent it in to a shop to be fixed, they cleaned the entire system and reset all connections and claimed to have it running for 24 hours without a problem. I was delighted only to find the exact same problem when I got it back. i never actually dealt with them though it was my father who took it in for me and spoke to them. He does not know anything about computer he just knew the guy in the shop. So I am on my own now because I can't afford to get this fixed.
I tried the computer with a different HDD and with no soundcard in but the problem persists.
I monitored the temps with speedfan and all are normal.
Reformated to no avail so its hadrly a virus.
Tried different power outlet to no avail.
It's unlikely to be the CMOS battery as the mobo is less than a year old.
