Pc keeps freezing

So I have a fresh build with a new install of windows7 ultimate. I'm using a xfx 750i sli mono, an e8400 processor, evga gtx460se video card, 4 gigs of corsair xms2 ddr2 ram, raidmax rx500s power supply, and a 250gb Sara hard drive. When I first built the system, I could go into windows and do whatever I wanted. Two days later, it freezes at the windows is stArting screen. I've removed a stick of ram, switched the sticks around, doubl checked the wiring, it still freezes. The fans keep running and the hd light feels flashing. I really need some advice. Thanx in advance

 

So you can't boot in to Windows properly at all? What about safe mode?

What sort of "freeze" is it - does the computer BSOD, kind of stutter and freeze, etc?

Go into BIOS when you boot up and see how hot the CPU is running.

 

The hottest the CPU has gotten was 43c after a while of use. No bsod just a locked screen. The fans all still run, just can't do anything except a hard reset. I can't even turn caps lock on. Every once in a while it will load into windows, but when I start downloading something, it just freezes.. No stuttering, just a locked screen. The CPU I running at 34c

 

Anyone? Please help me. I'm at my wits end.

 

Have you tried scanning with malwarebytes or Superantispyware.maybe it is infected with something.

 

I'm not sure to be honest. If you have your Windows discs, perhaps try repairing the install? Something might have become corrupted. You could also try booting off the install disc to run 'chkdsk' in the recovery console (I think that's possible).

I'd be inclined to suggest faulty hardware somewhere along the way though, potentially HDD or RAM.

So you experience this freeze up with both sticks of RAM used independently of one another?

 

I've tried in every dimm slot and indipendent with each stick. I knew the hdd was good, I had it in another build I had. I formatted the hdd an did a clean install of windows7 ultimate. I cant runn any tests, because the pc almost never gets to windows. I tried running memtest yesterday and it got to 15 min and it froze at 87% wint no errors. I'll try to use the install disk to repair. If that don't work I'll try a new install of windows. If that doesn't work I'll buy some new ram tomorrow. Thanx for the help.

 

So you had memtest on a CD, booted from it, ran to 87% and your PC locked up even then?

I'm running out of suggestions off-hand, sorry. Let us know how you get on.

 

Ripper- exactly. It just locked up. No button on the key oars would do anything and the timer froze. Ddp- ill give it a try. I tried to repair wi does with my windows 7 disc. Startup repair didn't fix anything. So I reinstalled window with a reformating. It let me log in to wi does and get online for ten mInutes and froze again. Restart and licks back uP at the windows starting screen. I'll try like you said n see what happens. Thanx

 

So today started messing with the pc again. Got it to boot into safe mode a couple of times after I switched the Sata port. Tried 5 times boot in safe mode. Even played a couple if vids on YouTube after I dl flash player. It still will not load regular windows. I'm going to change the CMOS battery just because I have one. Any ideas on what I need to do or what's wrong. Any advice is appreciated. Thanx again for all the help guys

 

When you're in safe mode temporarily, can you get in to device manager and see if it reports any errors with the SATA channels (yellow error triangles)?

Have you managed to try with an IDE drive? Perhaps you could use a converter to hook your SATA drive/cable up to one of the IDE channels - it would be easier, if you're certain the HDD/cable aren't to blame.

 

Nothing has an error. I used the h/d and cable in a older build I did and it worked fine.. I started the pc with a fresh copy of windows. I can buy an adapter. Take a couple of days to get here. I just don't understand what the problem is. Never had this problem before.

 

Perhaps you got a faulty motherboard. Have you tried another PSU, just because?

Presumably replacing the CMOS battery and consequently resetting the BIOS didn't fix anything?

 

Replacing the battery didn't fix it. I've got another power supply, but it's older and doesnt have any 6 or 8 pin power plugs and I need both. I'm thinking it the mobo, but I need to try everything before I try n return it

 

The thing that I don't understand is why I can go into safe mode n everything works fine, but I can't load windows

 

I'm going to pick up an IDE h/d today. I'll let u guys know how it goes later
