Hi guys, I'm new here. Having a bad CPU problem so decided to ask around to see if I can actually solve the problem. Any form of help will be greatly appreciated, I'm at my wits' end! Thanks! =]
The situation is this:
About 6 months ago, I started having this weird problem in which my CPU will sometimes not boot up. What happened was that whenever I powerup, the power will come on, everything will start whirring (CPU fan, my 8800 GTS fan, casing fan and everything else that should whir), this will go on for about 2-3 seconds before the CPU then shuts off itself. Without me touching anything, the CPU will come on again by itself and the process repeats itself until I actually turn off the power supply. Strangely, this does not happen all the time. Sometimes, when I leave it alone for some time and trying powering up again, my computer boots and I'll regain normal function. One day, I got fed up and opened up the case. I ensured that all the connections were properly connected and voila, for 6 months, the problem did not happen again.
Recently however, the problem resurfaced itself. I did what I did previously but I was not successful in resolving the problem. (I wasn't even sure that what I did solved the problem) In rare cases, the CPU will power up and stay powered, but there isn't any POST and my monitor is left in standby mode. Sometimes when it did boot up, the computer would hang within minutes (sometimes hours, if I'm lucky). I noticed that when it hanged, all my USB devices powered down, except for a wireless network adapter (Linksys WUSB54G). And sometimes when I'm really lucky, I would be able to use the computer normally. I'm not sure if it's because of overheating because RealTemp would show my Core1 Temp as 60deg and my Core2 deg as 37-40+ deg. I have no idea why my Core1 temp is ALWAYS constant at 60deg and never ever changes. Additionally, RealTemp shows my system temperature as 30+ - 40+ so I'm really not sure which means what. My ASUS 8800 GTS 512MB is OC-ed and has temperatures ranging from 60 - early 70s, which at first I took to be rather high but upon further enquiries, I was told that early 70s is still acceptable.
My specs are as follows:
Intel Core 2 Duo E8400 3.0 Ghz @ 7.5 x 400 Mhz (I had to because of my RAM settings)
Kingston HyperX 4x1 GB sticks at 4-4-4-12, 800 Mhz
CoolerMaster Real Power M520 @ 520W
ASUS 8800GTS 512MB TOP Edition
2x250 Seagate HDD on RAID0
If needed : 1x Razer Tarantula Keyboard using 2 USB ports
1x Razer Diamondback 3G using 1 USB port
1x WUSB54G (linksys wireless network adapter using 1 USB port)
Sorry for the long post, I'd like to be as detailed as possible.
Any help will be greatly, greatly appreciated!
Thanks in advance!
