I built my computer about a month and a half ago. The build went fine with no problems. The computer was working until this Saturday 4/9/11.
Part 1: The Storm
This past Saturday there was a pretty serious electrical storm. My computer is plugged in along with my TV, router, and modem to a very old power surge protected power strip. I do not know if the power surge protection is in working order. I weathered the massive storm and attempted to turn on my computer…
Part 2: The beeping
Once I pushed the power button to my rig it gave a post code that I had never heard before.
1. Long Beep
3. 3 Short beeps
5. 8-12 very short beeps.
(From what I can tell this a memory failure post code)
I kept turning the computer on and off in an attempt to record the post code.
Part 3: The silence.
After about 5 times turning the computer on and off it stopped making the post code. The computer would not post at all. All the fans would turn on and run. The HDD would spin. Everything would appear to be normal but no image on the monitor and no post.
Part 4: The RAM
I called my friend and told him about the problem. He said 9 times out of 10 it’s the RAM. My ram is two sticks two gigs.
I have four slots on my MOBO. The mem was originally in slot 1 and 2.
1. Took RAM out of slot one = would not power up (no fan spinning)
2. Returned RAM to slot one and removed ram from slot 2 = would not power up.
3. Returned RAM to slot one and two = would not power up.
4. Put RAM in slot three and four = computer turned on but no post.
5. Took RAM out of slot four = turned on but no post
6. Returned RAM to slot four and removed from slot three = turned on but no post.
7. Took RAM out of slots three and four (no ram in comp) = turned on but no post
Currently the ram is in slot three and four.
Part 5: The video card.
Because no image was displaying I thought “perhaps the video card is f’d”
I removed the GPU. The computer once again turned on but would not post.
Part 6: CMOS
Per the MOBO manual I removed the CMOS battery for 5 seconds and returned it. The computer would turn on but still not post. I then took the jumper and moved it to the reset position for 5 seconds then returned it. The computer would turn on but still not post.
PSU: Antec 650 green.
CPU: AMD Phenom II x 4 955
MOBO: Asrock 770 extreme 3
MEM: A-DATA XPG Gaming Series 4GB (2 x 2GB) 240-Pin DDR3 1600
GPU: Sapphire 5870
1. Its probably not the RAM
a. I took the RAM to my friends house and plugged both sticks into his computer. The computer posted with no problems.
b. I think the MEM is fine.
2. The storm could have fried something.
a. The MOBO could be fried from the electrical storm but I do not see any scorching on any of the cards or RAM.
b. The other components that were plugged into the power strip seem to be fine.
c. My router was messing up a little bit (turning itself on and off) on Saturday night but it is no longer doing that and is working.
3. Could be the MOBO
a. Because I got no response with the CMOS changes I may need to replace the MOBO.
4. Could be the PSU
a. Have not tested the PSU yet. Maybe this is the problem?
5. Could be the CPU
a. Have not removed the heat sink to look at the CPU yet.
6. Could be the HDD?
a. Probably not: why would the HDD cause the rig not to post?
If anyone has any ideas as to what I should do next. Please let me know.
