Tech advice needed

Hi folks. Been having technical problems everywhere today, from rats in the roof cavity to boot problems with my PC. The rats I can handle (they’re not getting in to the house yet), but the PC I’m worried about. I’ve included in the extended entry, the symptoms and the diagnosis I have made. Any advice or assistance anyone else has on the matter would be much appreciated.

EDIT: I should add this is a motherboard that was purchased and installed last September and the chip was purchased then, too. And the bios beeps I’m getting would indicate a memory error.

I think my PC problems might be layered. I’ve been having troubles occasionally with the CDRW (not recognising disks, not opening door, etc) and it seems to be the CD spin start that has stalled startup on the occasions that the BIOS beeps have occurred. I’m also concerned about CPU and HD0 temperatures and the seating of the RAM.

But I guess I should just give you a low-down of what happened, complete with details. Any advice any of you may have on possible/likely causes would be much appreciated.


It began a week or two ago when the CDRW basically wouldn’t read anything or even open its door until I rebooted. I just thought of it as a glitch.

Then a few days later I had long beeps on cold boot. Beeps lasted about 3-4 seconds and then there was a 1-2 second break before it happened again. Nothing came up on the monitor. I allowed myself the obligatory curse, and turned the machine off, waited 10 seconds and tried again. Same thing happened. I turned it off, waited 10 minutes and tried again and it started up fine, but I got a “CMOS checksum error: Defaults loaded” message. I pressed F1 and all seemed okay. Must admit I didn’t diagnose the problem though, beyond looking at my sheet of beep explanations, which seemed to indicate a memory error (at least that’s what most BIOS beep error code reports are saying).

No problems for the next few days, so again I just hoped for the best and then this morning I got the long beeps on cold boot again. I cursed again, and then turned the machine off for a few minutes. Once again the system started up fine with the exception of the checksum error message again. I started trying to look up similar problems online and after 10 minutes of working the system simply turned itself off and tried to boot again with no warning. Only it couldn’t boot and was emitting the long beeps. I left the machine off for a few minutes and it booted fine again with the checksum error. This time in the few minutes I had, I checked the system properties and found RAID controllers without drivers. But by the time I tried to look at a few sites to conitnue diagnosis, the system had switched off and was emitting the beeps again.


So I did the next logical thing and unplugged everything and took the side off the case. All seemed to *look* okay and I had a go at just jiggling and pushing the RAM dimm to ensure it was properly seated, reconnected keyboard and mouse and restarted – fine. All fans were working (on power supply as well as CPU, but the power supply fan was running extremely quietly). So I reconnected monitor and network cable and started again – no problem.

Next I reinstalled RAID controllers from the mobo CD (in the DVDRW drive just to be safe), and checked SystemFan temperatures. Here are the readings as I type this:

Temp1 (internal): 33 degrees. Temp2: 27 degrees. Temp3 (CPU): 49 degrees. HD0: 41 degrees.

I’ve seen the HD0 temp up at 43 degrees and since reconnection of all devices, the CPU has got up to 50 degrees, but only for a few seconds before reverting to 49.

So temperatures aren’t *great* as I have the side off the pc at the moment and so air is getting to the CPU more easily.


Basic specs are as follows…
Mobo: Gigabyte K7 Triton
CPU: Athlon XP 3200+
VGA: on board (long story attached to that, but I have a very nice VGA card I’m not actually using at the moment because in spite of the fact that it is also a Gigabyte brand device, the mobo won’t boot if it’s connected… and yes, I’ve tried changing the BIOS; no diff).

After all the above symptoms/activities occurred, I left the PC running an hour to see if it would shut down again and it hasn’t done so. Yet. But have checked BIOS upgrades, etc, and found I have the latest driver. Details are as follows (from eSupport BIOS agent):
Program: BIOS Agent Version 3.44
BIOS Date: 04/21/04
BIOS Type: Award Modular BIOS v6.00PG
BIOS ID: 04/21/2004-KM400A-8237-6A6LYG0WC
OEM Sign-On: GA-7VM400AM(F) F3
Chipset: VIA 82C3205 rev 0
Superio: ITE 8705/SiS 950 rev 2 found at port 2Eh
CPU: AMD Athlon(tm) XP 2171 Mhz MAX: 2800 Mhz
BIOS ROM In Socket: Yes
BIOS ROM Size: 256K
Memory Installed: 256 MB
Memory Maximum: 512 MB
Memory Slot 01: 256 MB
Memory Slot 02: 0 MB
I’ve also checked the CDRW and it seems to be working. Or at least it’s reading stuff.

(And yes, I know it’s insane I only have 256M RAM.)

So for the time being I don’t see what else I can do, other than keep an eye on things and maybe investigate new cooling for the system. And I’m pricing RAM too. I had forgotten I’m only running on 256M RAM and that appears to be Kingston PC3200 DDR RAM at that.


So. Have I missed anything? Should I turn this thing off and not reboot until I have better cooling? Should I remove the CDRW? Any advice and any diagnosis suggestions would be much appreciated. Also, FWIW, I’m speaking of a box which is running XP SP2, fully patched, firewalled and virus-protected. Not that that means jack when it comes to hardware problems (which this clearly is) but it might help in terms of driver compatibility.

Anyway – I’d be grateful for any suggestions.
