Hey guys. Recently - just over 1 week ago, out of the blue, my pc started playing up (whats new lol). Problem: the Taskbar would freeze, as well as all of the icons on desktop. Also the programs in startup bar wouldnt load and every time i hovered my mouse over the taskbar a "hourglass" would appear. I restarted my pc thinking that the OS (Win XP SP2) just didnt load correctly, but this problem kept happening. Now every so often my pc would load perfectly, no problems, tho most of the time it would *uck up, like i explained above. Seeing that this problem was eratic, i decided id format **simple solution**. Once formatted and win xp installed, everything worked fine. I was happy again lol. Tho after a few restarts/shutdowns the problems started again! same symptoms!. After stuffing around with windows for a bit, i ended up formatting 6 times in total, and loading up 3 Different Windows. - Win XP SP2 - Win XP - Win 2000 The only thing i could do on my pc (when it froze up) was CTRL+ALT+DEL and run a new process. So i loaded CMD and opened up firefox. thankfully it worked. I got on the net and after a few hrs of searching around google i found that its either some Embedded Virus :S - which i doubt; or an I/O Error.....thus Hardware Now here's my pc Config AMD Athlon 64 3200+ (Stock cooling) ASUS A8N-SLI Premium mobo 2 x 512MB Corsair Value RAM 400Mhz 1 x 120GIG WD 7.2k rpm 8MB Cache HDD (Win XP Boot) 1 x 200GIG (same specs) ... (File Storage drive) 2 x Nvidia 6600GT 128MB (SLI) 1 x DVD-ROM ( its old and i dont remember the brand) 1 x Sony DVD/CD-RW combo 450W PSU Thermaltake So, I started taking out drives 1 by 1. I took out the 2 Optical drives; no change. I removed the RAM and put in a 256stick; no change. I took out the 200gig HDD; no change. I took out 1 Video card; no change. The only thing i could see that was the problem now was either the Mobo, or HDD - i dont think its the cpu, but i havent tested it with another pc. I took out the 120 gig Windows Drive and put in an old 40gig Samsung. I formatted it and loaded Windows. I installed all my other drives inc. SLI and BAM!!!! IT WORKED !!! .......for about 3 days, till the same problems occured again. After yelling and screaming for a few hrs, i realized that it HAD to be my mobo. The next day i called up my local pc store (centrecom.com.au) and talked to the tech. After explaining all this to him, we was convinced it was my IDE controller or Chipset. So since it was/and still is under warranty he just said to bring it back and they'll fix it up for me (sweet ) Now that day as i de-assembled my pc to repackage my mobo, i thought id test out the HDD's (120 & 40gig) on a seperate PC. This PC is older but still not too bad AMD Athlon XP 2800+ Gigabyte mobo 256 mb some **** Geforce So i loaded each HDD up on this pc as The boot drive. I tried the 40Gig first and THE SAME PROBLEM HAPPENED!!! I tried the 120gig next and the SAME **** HAPPENED AGAIN!! WTF!!! This is now on a completely Different mobo, Including a different chipset. Bahh!!! lol This means its BOTH HDD's that are stuffed, since they were the only 2 devices that i used on the old pc that came off the good pc 2 HDD's stuffed @ the same time????? possible? ultra-rare? my pc hates me? Im ready to go out and buy new equipment, but im not that rich, so i wanna make sure i know what exactly is broken before i buy it. Does anyone have any ideas/suggestions or anything to this problem???? Any help what so ever would be extremely appreciated!!! Thanks for your time guys email me @ firstname.lastname@example.org or post here if u need any more info on my pc or what i have tested.
