Windows 7: Computer problems

Hi all

Recently my computer has had a few occurrences of system_service_exception bsod errors. So today I decided to format the computer.

I went into to bios to check the settings and changed hard drive type from IDE to RAID in configure sata type as option, even though I do not have raided drives currently (I thought it would be faster than ACHI).

Since then the computer comes on when I press the power switch but turns itself off again after 2 or 3 seconds.



Im guessing its that setting I changed so I have the battery out atm and am waiting the stated 1 hour before putting it back in.

Do you guys agree this is the reason for this problem?

This would be worth a read:

yeah it was set to achi mode before.

Latest is when I turn it on first time, it immediately powers down. When I try a second time it lasts 2 or 3 seconds before it powers down. So I wonder whether its the front power switch shorting or a faulty psu.

have you taken out and reinserted all ram modules and cards?

may as well replug all sata/ide cables whilst you're at it?

no bios beeping i take it?

all fans spinning ok? heatsinks not loose or wobbly?

all i can think of for now - best of luck, old chap!

*edit* sorry if i'm stating the bleeding obvious, but you never know...

You say it was set to ide and did you get the reformat complete, and can you still get into the bios if not reformatted yet. If you can get into the bios set it back to were it was tht happened to me when I changed my setting in the bios to achi or raid.

The change should not have made a difference unless you were going from RAID to IDE. The change just tells different hardware to process the requests. The drives should have still worked normally.

I have had the same issue a couple of times on one PC I built. I took out the memory chips and the Gfx card and re-inserted them and the issue went away.

I had another issue with an earlier model and it was a $5 fan which took out the Gfx card and MB. It would take ages to start continually going from on to off and not booting. It would finally boot and be okay for the day. Replacing the Gfx card and MB fixed that issue but now the power supply is failing. heaps of continuous beeps at start up but once I finall manage to get it started it goes well. New PS on its way tomorrow.

Has not been a good month for me.

It does appear like its some fault with the psu. I shall take the case back to the repair shop and Im hoping that the work they did 2 years ago is still under guarantee.

Ive had the computer back from the repair shop yesterday. They suspected that the cpu cooler was shorting the mobo so they have replaced the Tuniq Tower with a Scythe Mugen II.

I formatted windows when I got it home but unfortunately Im still getting the same bsod error on files win32k.sys and cdd.dll. I have ran memtest86 and the ram passed all the tests. What other tests can I do to eliminate other hardware?

Did you do a full clean on the HD?
